Tea Time: Linden Flower Tea

Lindens make great trees for urban areas. A few species and hybrids in particular are commonly planted in parks, yards, and along the streets of cities across the northern hemisphere and have been for decades – centuries even. They cast dense shade, are tolerant of a variety of climates and soil conditions, and are generally easy to maintain. For much of the year as you move throughout the city you live in, you likely pass by dozens of lindens without thinking twice about them. They are ubiquitous, conventional, ordinary, common. Unless they’re in bloom. For a few weeks in early to mid-summer, flowering lindens produce an impossibly sweet fragrance that can’t be ignored. Along with the scent comes the sound of hundreds of buzzing bees collecting pollen and nectar from the pendulous blooms.

Lindens are trees and shrubs in the family Malvaceae and genus Tilia. Around 30 or so species are found in temperate regions across the northern hemisphere, mostly in Europe and Asia. Depending on who you ask, there are between one and three species native to North America. Tilia caroliniana and Tilia heterophylla are considered by some to be varieties of Tilia americana, or American basswood, which is distributed across central and eastern United States and north into parts of Canada. Another common name for linden is lime because words used to refer to the tree in older languages were similar to the word lime. The name basswood comes from the tree’s fibrous inner bark, known as bast.

Linden leaves are generally heart-shaped and asymmetrical with serrate margins. Small clusters of little yellow to white flowers form at the end of a slender stem attached to a narrow, ribbon-like, yellow-green bract. The bract aids in seed dispersal by helping the fruits float on the wind away from the parent tree in a manner similar to the samaras of maple trees. The fruits are small, round, hardened drupes that resemble little peas. The fragrant, nectar-rich flowers are not only favored by beekeepers for honey production, but also have a long history of being harvested for making tea (i.e. tisane). Linden flower tea is said to have a number of medicinal uses and health benefits, all of which I take with a grain of salt. This series of posts isn’t meant to be an investigation into the health claims of plants, but instead an opportunity for me – out of sheer curiosity – to try making tea out of a variety of different plants . If medicinal uses interest you, I encourage you to seek out credible, peer-reviewed sources.

I made linden flower tea from flowers I collected from Tilia cordata, commonly known as littleleaf linden. It was an easy one to find due to its popularity as an urban tree. The natural distribution of littleleaf linden extends from Britain across Europe and into western Asia. Its triangular-ovate shaped leaves are 4-10 centimeters long, glossy green on top, and pale green on the bottom with tufts of orange hairs along the leaf veins, concentrated at the base of the leaf where the leaf blade meets the petiole. The tree can reach up to 21 meters tall and has an oval or rounded-pyramidal shape, though many trees in urban areas are cultivars and can be smaller and more compact.

I harvested the flowers – bracts and all – in late June. It’s advised that they not be harvested directly after a rain (or after being hit by sprinklers), and that they are harvested when the flowers are newly opened. I presume this is because the flowers are at their freshest at this point and will be the best for making tea. I layed the flowers out to dry on a clean kitchen towel on top of a metal cake rack. It only takes 2 or 3 days for them to dry. After drying I removed and saved all the flowers and threw out the bracts and stems, but apparently you can use the entire inflorescence if you’d like.

There are several linden flower tea recipes online. I went with 3 cups of boiling water poured over 1 tablespoon dried linden flowers, covered and steeped for 15 minutes. The resulting tea was an appealing pastel yellow color. I tried it plain as well as sweetened with a little bit of honey. I preferred it sweetened, but unsweetened wasn’t too bad, just a little bitter. It has a floral taste and pleasant smell. Sierra said it tasted earthy, like something she wasn’t supposed to be drinking. Despite that odd review, she said she liked it. Since several sources discussed the calming, sleep-inducing effects of the tea, I made sure to drink it in the evening when it would be normal for me to be feeling sleepy. I suggest you do the same.

Eating Weeds: Japanese Knotweed

When I first learned that Japanese knotweed was edible, I had my doubts. Sure, lots of plants may be edible, but are they really something you’d want to eat? I know Japanese knotweed as one of the most notorious weeds on the planet. Its destructive, relentless, and prolific nature has landed it on the world’s 100 worst invasive species list, right up there with black rats, Dutch elm disease, and killer algae. Having encountered a fair number of Japanese knotweed stands, the first thing to come to mind has never been, “that looks delicious.” Mature stalks stand as tall as 3 meters with broad, leathery leaves and hollow, bamboo-like stems. Their late summer flowers – a mess of tiny white florets on sprawling flower stalks – are a pollinator’s delight and favored by beekeepers for their abundant nectar. I don’t doubt that the honey produced from such an encounter is tasty, but the plant itself? I needed convincing.

Finally, I looked into it. I came across recipes of Japanese knotweed pickles and learned that it was the young, early emerging shoots that were sought after. That changed my perspective. Certainly you wouldn’t want to gnaw on a woody, 4 foot tall Japanese knotweed stalk, but the tender stems as they’re just beginning to re-emerge from the ground in the spring? Now those might be worth trying.

emerging stems of Japanese knotweed (Reynoutria japonica)

Japanese knotweed (Reynoutria japonica) was introduced to Europe from Japan in the 1800’s, arriving at Royal Botanic Gardens Kew by 1850. At that point, it was a prized ornamental. Its thick stems spotted with reds and purples, its broad, shiny leaves, and its showy flower heads all gave it garden appeal. It was also found to be useful for stabilizing hillsides and reducing erosion, honey production, and as a rhubarb substitute (it’s in the same plant family as rhubarb after all). Not long after that, it made its way to North America. Certainly people must have been aware of its propagative prowess as they moved the plant around. It readily roots from root and stem fragments, plus it produces extensive rhizomes, working their way as deep as 3 meters into the soil and as far as 7 meters away from the parent plant. Perhaps that should have been cause for alarm, but how could anyone have predicted just how aggressive and widespread it would soon become?

Thanks to the plant’s rhizomes, Japanese knotweed grows in thick, many-stemmed stands, pushing out, shading out, and leaving very little room for other plants. The rhizomes are also tough and can push up through gravel, cement, and asphalt. They are notorious for damaging foundations, pipes, and even pushing their way through floorboards. If that’s not enough, Japanese knotweed is pretty much impossible to kill. Herbicides may set it back, but they generally don’t take it out. Cutting it down repeatedly can slow it down, but it may also encourage it to grow more thickly and spread out more widely. Smothering it can work, but you have to be prepared to keep it smothered for quite a while. The deep rhizomes are slow to die, and they may eventually find their way outside of the smothered area, popping up to destroy your efforts to contain it. You can try to dig it out, but the amount of dirt you’d have to dig to get every last root and rhizome really isn’t feasible in most circumstances.

But hey, you can eat it, and perhaps you should. A quick internet search reveals a number of ways the plant can be consumed – purees, chutneys, compotes, sorbets. I chose to go with pickled Japanese knotweed. It seemed simple and approachable enough and a good way to determine if I was going to like it or not. Room temperature brine fermentation is pretty easy. You basically put whatever you’re wanting to pickle in a jar, add whatever spices and things you’d like, fill the jar with salty water, then seal it shut and let it sit there for a few days. Before you know it, you’ve got pickles.

There are several recipes for pickled Japanese knotweed to choose from. I went with this one. The seasonings I used were a bit different, and the stalks I had weren’t as “chubby” as recommended, but otherwise my approach was the same. After a few days, I gave them a try. I was pleasantly surprised. I thought they tasted a little like nopales. Sierra reluctantly tried them and was also surprised by how good they were. They reminded her of pickled asparagus. Other sources describe them as lemony, crunchy, tart and suggest serving them with fish, ramen, or even adding them to a cocktail made with purslane. Many of the weeds I’ve tried have been a fun experience, but not necessarily something I need to repeat. Japanese knotweed pickles, on the other hand, could become a spring tradition for me, and since we’re pretty much stuck with this plant, I’m sure to have a steady supply.

Winter Trees and Shrubs: Northern Catalpa

The names of plants often contain clues that can either help with identification or that tell something about the plant’s history or use. The name, catalpa, is said to be derived from the Muscogee word, katałpa, meaning “winged head,” presumably referring to the tree’s winged seeds. Or maybe, as one writer speculates, it refers to the large, heart-shaped, floppy leaves that can make it look like the tree is “ready to take flight.” Or perhaps it’s a reference to the fluted, fused petals of the tree’s large, tubular flowers. I suppose it could mean any number of things, but I’m sticking with its seeds, which are packed by the dozens in the tree’s long, slender, bean-like fruits. The seeds are flat, pale brown, and equipped with paper thin, fringed appendages on either side that assist in wind dispersal – wings, in other words.

winged seeds of northern catalpa (Catalpa speciosa)

Catalpa speciosa, or northern catalpa, is a relatively fast growing, short-lived tree native to the Midwest and one of only two species in the genus Catalpa found in the United States. Its distribution prior to the arrival of Europeans appears to have been restricted to a portion of the central Mississippi River valley, extending west into Arkansas, east into Tennessee, and north into Illinois and Indiana. It has since been widely planted outside of its native range, naturalizing in areas across the Midwest and eastern US. Early colonizers planted northern catalpa for use as fence posts, railroad ties, and firewood. Its popularity as an ornamental tree is not what it once was a century ago, but it is still occasionally planted in urban areas as a shade tree. Its messiness – littering the ground below with large leaves, flowers, and seed capsules – and its tendency to spread outside of cultivation into natural areas are reasons why it has fallen out of favor with some people.

The oval to heart-shaped, 8 to 12 inch long leaves with long petioles rotting on the ground below the tree are one sure sign that you’ve encountered a catalpa in the winter time. The leaves are some of the first to fall at the end of the growing season, briefly turning an unmemorable yellow before dropping.

The leaf arrangement on northern catalpa is whorled and sometimes opposite. The twigs are easy to identify due to several unique features. They are stout, round, and grayish brown with prominent lenticels. The leaf scars are large, rounded, and raised up on the twig, looking a bit like little suction cups. They are arranged in whorls of three, with one scar considerably smaller than the other two. A series of bundle traces inside the scar form an ellipse. The leaf buds are tiny compared to the scar and are protected by loose, pointed, brown bud scales. Northern catalpa twigs lack a terminal bud. In the winter, seed capsules or the stalk of an old inflorescence often remain attached to the terminal end of the twig. The pith inside of the twig is thick, white, and solid.

Another common name for Catalpa speciosa is cigar tree, a name that comes from its up to 18 inch long, cigar-like seed capsules that hang from the otherwise naked tree throughout the winter. The sturdy, cylindrical pod starts out green in the summer and turns dark brown by late fall. Seed pods that haven’t fallen or already split open will dehisce in the spring time, releasing their papery seeds to the wind.

The young bark of northern catalpa is thin and easily damaged. As it matures, it becomes furrowed with either scaly ridges or blocky plates. Mature trees are generally twisted at the base but otherwise grow straight, reaching 30 to 60 feet tall (sometimes taller) with an open-rounded to narrow-oval crown.

maturing bark of northern catalpa (Catalpa speciosa)

Northern catalpa is one of the last trees to leaf out in the spring. In late spring or early summer, 10 inch long clusters of white, tubular flowers are produced at the tips of stems. Before the flowers open, they look a bit like popped popcorn, reminding me of a song from my childhood (which I will reluctantly leave right here). The margins of its trumpet-shaped petals are ruffled and there is yellow, orange, and/or purple spotting or streaking on the inside of the tubes.

Winter Trees and Shrubs: Netleaf Hackberry

Boise, Idaho is frequently referred to as the City of Trees despite being located in a semiarid region of the Intermountain West known as the sagebrush steppe where few trees naturally grow. It earns this moniker partly because the name Boise is derived from the river that runs through it (the Boise River), which was named La Rivere Boisse, or The Wooded River, by early French trappers. Although it flows through a largely treeless landscape, The Wooded River was an apt name on account of the wide expanse of cottonwoods and willows that grew along its banks. The fervent efforts of early colonizers to plant trees in large numbers across their new city also helped Boise earn the title, City of Trees. Today, residents continue the legacy of planting trees, ensuring that the city will remain wooded for decades to come.

As is likely the case for most urban areas, the majority of trees being planted in Boise are not native to the region. After all, very few tree species are. However, apart from the trees that flank the Boise River, there is one tree in particular that naturally occurs in the area. Celtis reticulata, commonly known as netleaf hackberry, can be found scattered across the Boise Foothills amongst shrubs, bunchgrasses, and wildflowers, taking advantage of deep pockets of moisture found in rocky outcrops and draws.

The western edge of netleaf hackberry’s range extends to the northwest of Boise into Washington, west into Oregon, and down into California. The majority of its range is found south of Idaho, across the Southwest and into northern Mexico, then east into the prairie regions of Kansas and Oklahoma. Previously placed in the elm family, it is now considered a member of the family Cannabaceae (along with hemp and hops). It’s a relatively small, broad tree (sometimes a shrub) with a semi-rounded crown. It grows slowly, is long-lived, and generally has a gnarled, hardened, twisted look to it. It’s a tough tree that has clearly been through a lot.

The leaves of Celtis reticulata are rough, leathery, and oval to lance shaped with serrate or entire leaf margins. Their undersides have a distinct net-like pattern that gives the tree its common name. A very small insect called a hackberry psyllid lays its eggs inside the leaf buds of netleaf hackberries in the spring. Its larvae develop inside the leaf, feeding on the sugars produced during photosynthesis, and causing nipple galls to form in the leaves. It’s not uncommon to see a netleaf hackberry with warty-looking galls on just about every leaf. Luckily, the tree doesn’t seem to be bothered by this.

The fruit of netleaf hackberry is a pea-sized drupe that hangs at the end of a pedicel that is 1/4 to 1/2 inch long. Its skin is red-orange to purple-brown, and its flesh is thin with a large seed in the center. The fruits, along with a few random leaves, persist on the tree throughout the winter and provide food for dozens of species of birds and a variety of mammals.

persistent fruit of netleaf hackberry (Celtis reticulata)

Celtis reticulata is alternately branched. Its twigs are slender, zig-zagging, and often curved back towards the trunk. They are reddish-brown with several pale lenticels and have sparse, fine, short hairs that are hard to see without a hand lens. The leaf scars are small, half-round, and raised up from the twig. They have three bundle scars that form a triangle. The buds are triangle-shaped with fuzzy bud scales that are slightly lighter in color than the twig. The twigs are topped with a subterminal bud, and the pith (the inner portion of the twig) is either chambered or diaphragmed and difficult to see clearly without a hand lens. 

twigs of netleaf hackberry (Celtis reticulata)

The young bark of netleaf hackberry is generally smooth and grey, developing shallow, orange-tinged furrows as it gets older. Mature bark is warty like its cousin, Celtis occidentals, and develops thick, grey, corky ridges. Due to its slow growth, the bark can be retained long enough that it becomes habitat for extensive lichen colonies.

Netleaf hackberry is one of the last trees to leaf out in the spring, presumably preserving as much moisture as possible as it prepares to enter another scorching hot, bone-dry summer typical of the western states. Its flowers open around the same time and are miniscule and without petals. Their oversized mustache-shaped, fuzzy, white stigmas provide some entertainment for those of us who take the time to lean in for a closer look.

Winter Trees and Shrubs: Eastern Redbud

Botanizing doesn’t have to end when the leaves fall off the trees and the ground goes frozen. Plants may stop actively growing during this time, but they are still there. Some die back to the soil level and spend the entire winter underground, leaving behind brown, brittle shells of their former selves. Others, particularly those with woody stems, maintain their form (although many of them leafless) as they bide their time while daylength dips and rises again, bringing with it the promise of warmer weather. Plants that leave us with something to look at during the winter can still be identified. Without foliage or flowers to offer us clues, we rely instead on branches, bark, and buds to identify woody species. In some cases, such features may even be more helpful in determining a certain species than their flowers and foliage ever were. Either way, it’s a fun challenge and one worth accepting if you’re willing to brave the cold, hand lens and field guides in tow.

In this series of posts I’ll be looking closely at woody plants in winter, examining the twigs, buds, bark, and any other features I come across that can help us identify them. Species by species, I will learn the ropes of winter plant identification and then pass my findings along to you. We’ll begin with Cercis canadensis, an understory tree commonly known as eastern redbud.

Eastern redbud is distributed across central and eastern North America, south of southern Michigan and into central Mexico. It is also commonly grown as an ornamental tree outside of its native range, and a number of cultivars have been developed for this purpose. Mature trees reach up to 30 feet and have short trunks with wide, rounded crowns. Its leaves are entire, round or heart-shaped, and turn golden-yellow in the fall. Gathered below the tree in winter, the leaves maintain their shape and are a light orange-brown color.

fallen leaf of eastern redbud (Cercis canadensis)

Eastern redbud is alternately branched with slender, zig-zagging twigs that are dark reddish-brown scattered with several tiny, light-colored lenticels. Older sections of branches are more grey in color. Leaf scars (the marks left on twigs after leaves fall) are a rounded triangle shape and slightly raised with thin ridges along each side. The top edge of the leaf scar is fringed, which I found impossible to see without magnification. Leaf buds are egg-shaped and 2-3 mm in length with wine-red bud scales that are glabrous (smooth) with slightly white, ciliate margins. Descriptions say there are actually two buds – one stalked and one sessile. If the second bud is there, it’s miniscule and obscured by the leaf scar. I haven’t actually been able to see one. Twigs lack a terminal bud or have a tiny subterminal bud that points off to one side. The pith of the twigs is rounded and pale pink. Use sharp pruners or a razor blade to cut the twig in half lengthwise to see it.

Bark is helpful in identifying woody plants any time of year, but is especially worth looking at during the winter when branches have gone bare. The bark of young eastern redbud is grey with orange, furrowed streaks running lengthwise along the trunk. In mature trees, the bark is gray, scaly, and peels to reveal reddish-brown below.

Eastern redbud is in the bean family (Fabaceae) and its flowers and fruits are characteristic of plants in this family. Fruits can persist on the tree throughout the winter and are another way to identify the tree during the off-season. Seed pods are flat, dark red- or orange-brown, and up to 2.5 inches long with four to ten seeds inside. The seeds are flat, round, about 5 millimeters long, and ranging in color from orange-brown to black.

persistent fruits of eastern redbud (Cercis canadensis)

seeds of eastern redbud (Cercis canadensis)

Eastern redbud flowers in early spring before it has leafed out. Clusters of bright pink flowers form on old branches rather than new stems and twigs. Sometimes flowers even burst right out of the main trunk. This unique trait is called cauliflory.

Tea Time: Lemon Balm Tea

Cooler weather has me thinking about hot tea again. This time around I decided to go with something I’ve already tried and know that I like. Despite the fact that lemon balm can be quite abundant and readily available, I don’t really drink it that often. Yet, considering claims made regarding its calming nature, this is definitely the year to have it.

lemon balm (Melissa officinalis)

Melissa officinalis is an herbaceous perennial native to the Mediterranean Basin and beyond. It has been widely planted outside of its native range and has become naturalized – some might say weedy – in many parts of the world. It self-sows easily and also spreads readily via stolons and/or rhizomes. It isn’t picky about soil type and grows well in both sun and part shade. Lemon balm is in the mint family and acts in a similarly aggresive way to some of its relatives, but luckily isn’t nearly as tenacious as mint in its tendency to dominate a garden bed.

The leaves of lemon balm have a wrinkled appearance, are triangular or wedge-shaped with toothed margins, and are arranged oppositely on square stems up to three feet tall. Small, white or pale yellow (sometimes pale pink) flowers are inconspicuous and produced in the axils of leaves. They are often sparse enough to be hardly noticeable. This plant’s aesthetic appeal is all about its pleasant and prolific green foliage. Yet, despite the simplicity of its flowers, lemon balm is known for being attractive to bees and is often propagated specifically to feed honeybees. In fact, the genus name Melissa apparently means honeybee in Ancient Greek.

lemon balm flower

The leaves of lemon balm can be consumed fresh or dried and have a number of other uses besides tea. They have a sweet, lemon-like scent and, like so many other herbs with a long history of human use, have a wide array of medicinal claims associated with them. Many sources agree on lemon balm’s ability to calm the nerves, reduce stress and anxiety, and fight off insomnia. According to The Herb Society of America’s Essential Guide to Growing and Cooking with Herbs, lemon balm “has been used as a relaxing agent and as an aid to restful, nightmare-free sleep.” Sounds like I could use more lemon balm in my life.

dried lemon balm leaves

Lemon balm tea can be made with either fresh or dried leaves, but fresh leaves seem to make a more flavorful tea. I had only tried tea made from dried leaves until recently and have decided that I prefer fresh leaves. Simply harvest a few leaves, cut or tear them apart to release the lemony flavor, place them in a cup, and cover them in hot water. Some recipes (like this one) suggest adding honey, while others mix lemon balm with additional herbs known for their lemon-like flavor or relaxing nature (lemon thyme and lemon verbena, for example). Sierra was immediately taken by lemon balm tea when she tried it – in contrast to her experience with violet leaf tea – and even said it was right up there with her preferred black teas. I’m not surprised, as it is one of my favorite teas as well.

Tea Time: Violet Leaf Tea

The genus Viola is large and widespread. Its flowers are easily recognizable and obviously popular. A significant number of Viola species, hybrids, and cultivars are commercially available and commonly planted in flower beds and container gardens. Certain species have even become weeds – vicious lawn invaders in some people’s opinion. Violets (or pansies in some cases) are also edible. Their leaves and/or flowers can be used in salads, drinks, and desserts. One way to use the leaves is to make tea, so that’s what I did.

I imagine you can make tea from any Viola species, but after some searching I found that two species frequently mentioned are Viola odorata and Viola sororia – two very similar looking plants, one from the Old World and the other from the New World.

sweet violet (Viola odorata)

Viola odorata – commonly known as sweet violet, wood violet, or English violet – is distributed across Europe and into Asia and has been widely introduced outside of its natural range. It has round, oval, or heart-shaped leaves with toothed margins that grow from the base of the plant, giving it a groundcover-type habit. Its flowers range from dark purple to white and are borne atop a single stem that curves downward at the top like a shepherd’s crook. It has no leafy, upright stems, and it spreads horizontally via stolons and rhizomes. The flowers are distinctly fragrant and have a long history of being used in perfumes.

One way to get a good whiff of these flowers is to try a trick described in the book The Reason for Flowers by Stephen Buchmann:

Go into a garden or any natural area and select one or more flowers you want to investigate…. Select a small, thoroughly washed and dried glass jar with a tight-fitting lid. Place just one type of flower in the jar. Set your jar in a warm, sunny place such as a windowsill and come back in an hour or two. Carefully open the lid and sniff…. If you’ve selected a blossom with even the faintest scent, you should be able to smell it now, since the fragrance molecules have concentrated inside the jar.

Viola sororia – native to eastern North America –  is also commonly planted outside of its native range. It’s clearly a favorite, having earned the distinction of state flower in four U.S. states. Known as the common blue violet (or myriad other commons names), it looks and acts a lot like sweet violet. I distinguish them by their flowers, which are wider and rounder (chunkier, perhaps) than sweet violet flowers, and their leaves, which are generally more heart-shaped. Feel free to correct me. If, like me, you’re having trouble identifying violets, keep in mind that Viola species are highly variable and notorious hybridizers, so don’t beat yourself up over it. It’s their fault, not yours.

common blue violet (Viola sororia)

Violets bloom when the air is cool and the days are short. They are among the earliest plants to flower after the new year and among the latest plants flowering as the year comes to a close. In his entry on violets in The Book of Forest and Thicket, John Eastman refers to these early bloomers as “this low, blue flame in the woods.” They are like “a pilot light that ignites the entire burst of resurrection we call spring.” I can’t really picture spring without them. I find their unique flowers so intriguing that I fixate on them whenever I see them. And once I learned that I could make a tea out of their leaves, I had to try it.

I used the leaves of Viola odorata (or what I, with my amateur skills, identified as V. odorata). I picked several of what looked to be young leaves and left them to dry in the sun for several days. Later, I chopped them up and brewed a tea according to the instructions found on this website, which suggests using one tablespoon of dried leaves in sixteen ounces of water. Apparently, a little goes a long way, and I probably could have used fewer leaves than I did.

dried, chopped up leaves of sweet violet (Viola odorata) for making tea

The tea has a nice green color and smells a bit like grass to me. It may even taste like grass. I found it fairly bitter. Sierra didn’t like it and called it musty. I enjoyed it, but would likely enjoy it more if I hadn’t made it quite so strong. The aforementioned website also recommends combining violet leaf with other things like mint, dandelion, clover, and/or chamomile. I imagine a combination of ingredients could be better than just violet leaf on its own. Another site warns that “some of the wild violets have an unpleasant soapy flavor,” so that’s something to keep in mind when selecting your leaves for tea and other things. Either way, violet leaf tea is an experience worth having.

Awkward Botanical Sketches #3: The Ginkgo Edition

For most of my life, ginkgo has been a meaningful tree to me. I remember first learning about it as a fourth grader. Our teacher had assigned us each to make a leaf collection. My grandparents heard about my assignment and sent me a ginkgo leaf from a tree growing in their front yard. It was unlike any other leaf in my collection, and it had a fascinating back story. Not only is it the only living tree in its genus and family, it’s also the only extant species in its division (Ginkgophyta). It was around during the time of the dinosaurs, and is considered a living fossil. I felt honored to have it, especially when I learned that I was the only kid in the class that had one.

Since then I’ve considered Ginkgo biloba to be one of the best trees. It continues to fascinate me. It’s a beautiful tree with captivating foliage, and it’s resiliency is amazing. It’s no wonder that depictions of ginkgo are so common across many cultures.

Since I love looking at ginkgo leaves, I decided to try to draw them. If you’ve been following this series of posts, you’ll remember that my drawing skills are severely lacking. A shape as simple as a ginkgo leaf should be easy to draw, but not for me. I resorted first to tracing leaves that I had pressed, and then going from there. Below are some of my results.

Finally, a freehand drawing of a cluster of ginkgo leaves in my pocket notebook in celebration of Staple Day.

Field Trip: Green Spring Gardens and Meadowlark Botanical Gardens

Last month, Sierra and I were in Washington D.C. for the American Public Gardens Association annual meeting. We didn’t get to visit nearly as many gardens as I would have liked. Time was limited, and rain spoiled things a bit. However, we did get a chance to take an all day field trip to a few gardens in nearby Virginia. A couple of the gardens we visited on that trip were Green Spring Gardens in Alexandria, VA and Meadowlark Botanical Gardens in Vienna, VA.

Both gardens are quite large – Green Spring is over 30 acres and Meadowlark covers over 90 acres – and there wasn’t time to get the full experience at either location. Thus, my photos are scant and obviously not fully representative of either place. Either way, we had a good time visiting both gardens.

Green Spring Gardens

The Fairfax County Parks Authority owns and operates Green Spring Gardens. Among other partnerships, they receive considerable support from a non-profit organization called Friends of Green Spring. Although it was the wrong time of year to see them in bloom, Green Spring Gardens has a nationally accredited witch hazel collection that I’m sure would be worth checking out in the winter months. I enjoyed walking through the native plant garden, seeing the newly planted crevice garden, and learning about magnolia bogs from a friendly and enthusiastic volunteer.

Meadowlark is owned and operated by NOVA Parks. Its immense size made it difficult to decide what to check out in the little time we had, but we were happy with our decision to stop by the wetlands (to see the knees on the Taxodium distichum) and walk through the forested nature trail. We also had fun watching all the bumblebees lumber about from flower to flower.

Awkward Botanical Sketches #2: The Dear Data Edition

In this special edition of Awkward Botanical Sketches, I took some inspiration from a book called Dear Data by Giorgia Lupi and Stefanie Posavec. In this book, two friends separated by an ocean chose something about their lives to collect data on every week for a year, then they exchanged the data they collected via weekly postcards. They did this by drawing out a representation of their data on the front of the postcard, along with a key to the drawing on the back. It seemed like a fun thing to do, so I decided to try it. Rather than mailing my postcards to someone across the sea, I am sharing them here.

My ability to creatively present the data I collected pales in comparison to Lupi and Posavec, but I had fun giving it a shot. Most importantly, it satisfied my quest to draw more. This first postcard is all about the weeds I came across in a week.

Whenever I listen to music I make a mental note of any botanical references made in the lyrics. I generally don’t do anything with these mental notes – unless, of course, I’m writing something about them (see this Botany in Popular Culture post, for example) – but this time I did. Saturday was a particularly busy day because I was listening to a lot of Ghost Mice.

My obvious obssesion with weeds and my intention to write a weeds-themed book someday – plus my career as a horticulturist – means that I frequently find myself involved in activities and conversations involving weeds. I wasn’t exactly sure how to track that, so this is my lousy attempt at doing so. In case you’re wondering what I was up to on Saturday (the big, blue circle), this tweet and Instagram post should help explain things.
