Eating Weeds: Chicory

Over the course of human history, plant species once esteemed or considered useful have been recategorized into something less desirable. For one reason or another, plants fall out of favor or wear out their welcome, and, in come cases, are found to be downright obnoxious, ultimately losing their place in our yards and gardens. The particularly troublesome ones are branded as weeds, and put on our “do not plant” lists. These plants are not only unfavored, they’re despised. But being distinguished as a weed doesn’t necessary negate a plant’s usefulness. It’s likely that the plant still has some redeeming characteristics. We’ve just chosen instead to pay more attention its less redeeming ones.

Chicory is a good example of a plant like this. At one point in time, Cichorium intybus had a more prominent place in our gardens, right alongside dandelions in fact. European colonizers first introduced chicory to North America in the late 1700’s. Its leaves were harvested for use as a salad green and its roots were used to make a coffee additive or substitute. Before that, cultivation of chicory for these and other purposes had been going on across Europe for thousands of years, and it still goes on today to a certain extent. Along with other chicory varieties, a red-leafed form known as radicchio and a close cousin known as endive (Chicorium endivia) are grown as specialty crops, occassionally finding their way into our fanciest of salads.

Chicory’s tough, adaptable nature and proclivity to escape cultivation have helped it become widespread, making itself at home in natural areas as well as urban and rural settings. Its perennial life history helps make it a fixture in the landscape. It sends down a long, sturdy taproot and settles in for the long haul. It tolerates dry, compacted soils with poor fertility and doesn’t shy away from roadside soils frequently scoured with salts. It’s as though it was designed to be a city weed.

Unlike many other perennial weeds, chicory doesn’t spread vegetatively. It starts its life as a seed, blown in from a nearby plant. After sprouting, it forms a dandelion-esque rosette of leaves during its first year. Wiry, branched stems rise up from the rosette in following years, reaching heights of anywhere from about a foot to 5 or 6 feet. When broken, leaves, stems, and roots ooze a milky sap. Abundant flowers form along the gangly stems. Like other plants in the aster family, each flower head is composed of multiple flowers. Chicory flower heads are all ray flowers, lacking the disc flowers found in the center of other plants in this family. The petals are a brilliant blue – sometimes pink or white. Individual flowers last less than a day and are largely pollinated by bees. The fruits lack the large pappus found on dandelions and other close relatives, but the seeds are still dispersed readily with the help of wind, animals, and human activity.

The most commonly consumed portions of chicory are its leaves and roots. Its flowers and flower buds are also edible. Young leaves and blanched leaves are favored because they are the least bitter. Excluding the leaves from light by burying or covering them up keeps them pale and reduces their bitter flavor. This is standard practice in the commercial production of certain chicory varieties. The taproots of chicory are dried, roasted, and ground for use as a coffee substitute. They are also harvested commercially for use as a natural sweetener due to their high concentration of inulin.

my puny chicory root

I harvested a single puny chicory root in order to make tea. On my bike ride to work there is a small, sad patch of chicory growing in the shade of large trees along the bike path. I was only able to pull one plant up by the roots. The others snapped off at the base. So, I took my tiny root, dried and roasted it in the oven, and ground it up in a coffee grinder. I followed instructions for roasting found on this website, but there are many other sources out there. I had just enough to make one small cup of tea, which reminded me of dandelion root teas I have had. Sierra found it to be very bitter, and I agreed but still enjoyed it. I figure that wild plants, especially those growing in stressful conditions like mine was, are likely to be more bitter and strong tasting compared to coddled, cultivated ones found in a garden.

When I find a larger patch of feral chicory, I hope to try one of several recipes included in Luigi Ballerini’s book, A Feast of Weeds, as well as other recipes out there. I’ll be sure to let you know how it goes.

Party Time for Puncture Vine, Year Two

Party Time for Puncture Vine, Year Two

A noxious weed brought Boiseans together for the second year in a row. After a successful inaugural year, the Boise Goathead Fest returned to downtown Boise, Idaho on the 2nd and 3rd of August. The festival’s namesake comes from a particularly destructive weed whose spiky fruits are notorious for puncturing bike tires. Known commonly as goathead or puncture vine, Tribulus terrestris is abundant in the Treasure Valley and the bane of area bicyclists. Organized by the Boise Bicycle Project and other bike-centric non-profits, Boise Goathead Fest is a celebration of bike culture, as well as an opportunity to spread awareness about this problematic plant.

For the two months leading up to Goathead Fest, Treasure Valley residents were encouraged to pull as many goatheads as they could get their hands on. Those who took on the challenge were rewarded with tokens to be redeemed at the Fest for drinks or ice cream. Trophies and prizes were also presented to those who pulled the most goatheads over the two month period. This effort resulted in thousands of pounds of goatheads being removed from the area, saving bicyclists from countless flat tires and slimming down puncture vine’s extensive seed bank.

After two months of collecting goatheads, it was time to celebrate. The two day long party consisted of live music and DJs, a huge bike parade around downtown Boise (for which participants were encouraged to decorate their bikes and wear costumes), and a variety of other bike-themed and non bike-themed activities. Goathead education continued during the Fest with the help of folks from Ada County, City of Boise, Idaho Botanical Garden, and others.

With all of this attention and awareness focused on a single noxious weed, might it be possible to eliminate it from our community and free ourselves from ruined rides and trashed tires? The seeds of puncture vine are relatively short lived, and as an annual plant, seeds are its only method of reproduction. Even if we can’t altogether eliminate it, we could certainly see a dramatic reduction in its abundance and distribution. Perhaps in the future we will spend less time pulling it and more time celebrating its rarity, reflecting back on the time when punctures permeated our pedal-powered lives. Whatever the result, puncture vine has brought our community together once again. If such a loathsome weed can bring people together in celebration like this, perhaps it’s not entirely bad.

Selections from the Boise Biophilia Archives

For a little over a year now, I’ve been doing a tiny radio show with a friend of mine named Casey O’leary. The show is called Boise Biophilia and airs weekly on Radio Boise. On the show we each take about a minute to talk about something biology or ecology related that listeners in our local area can relate to. Our goal is to encourage listeners to get outside and explore the natural world. It’s fascinating after all! After the shows air, I post them on our website and Soundcloud page for all to hear.

We are not professional broadcasters by any means. Heck, I’m not a huge fan of talking in general, much less when a microphone is involved and a recording is being made. But Casey and I both love spreading the word about nerdy nature topics, and Casey’s enthusiasm for the project helps keep me involved. We’ve recorded nearly 70 episodes so far and are thrilled to know that they are out there in the world for people to experience. What follows is a sampling of some of the episodes we have recorded over the last 16 months. Some of our topics and comments are inside baseball for people living in the Treasure Valley, but there’s plenty there for outsiders to enjoy as well.

Something you will surely note upon your first listen is the scattering of interesting sound effects and off the wall edits in each of the episodes. Those come thanks to Speedy of Radio Boise who helps us edit our show. Without Speedy, the show wouldn’t be nearly as fun to listen to, so we are grateful for the work he does.

In this episode, Casey and I explore the world of leaf litter. Where do all the leaves go after they fall? Who are the players involved in decomposition, and what are they up to out there?

 

In this episode, Casey gets into our region’s complicated system of water rights, while I dive into something equally complex and intense – life inside of a sagebrush gall.

 

In this episode, I talk about dead bees and other insects trapped and dangling from milkweed flowers, and Casey discusses goatheads (a.k.a. puncture vine or Tribulus terrestris) in honor of Boise’s nascent summer celebration, Goathead Fest.

 

As much as I love plants, I have to admit that some of our best episodes are insect themed. Their lives are so dramatic, and this episode illustrates that.

 

The insect drama continues in this episode in which I describe how ant lions capture and consume their prey. Since we recorded this around Halloween, Casey offers a particularly spooky bit about garlic.

 

If you follow Awkward Botany, you know that one of my favorite topics is weeds. In this episode, I cover tumbleweeds, an iconic western weed that has been known to do some real damage. Casey introduces us to Canada geese, which are similar to weeds in their, at times, overabundance and ability to spawn strong opinions in the people they share space with.

 

In this episode, I explain the phenomenon of marcescence, and Casey gives some great advice about growing onions from seed.

 

And finally, in the spring you can’t get by without talking about bulbs at some point. This episode is an introduction to geophytes. Casey breaks down the basics, while I list some specific geophytes native to our Boise Foothills.

 

Field Trip: Orton Botanical Garden

In the inaugural year of this blog, I wrote a short post about a visit to Plantasia Cactus Gardens, a botanical garden in Twin Falls, Idaho that specializes in cold hardy cactus and other succulents. I finally made a return visit all these years later (thanks to a co-worker who organized the trip). Back in 2013, the garden was private but open to the public by appointment. Today, the garden is still open by appointment but is now a 501(c)(3) non-profit organization with a new name: Orton Botanical Garden.

With the name change and non-profit status comes a new mission statement. The garden has been an impressive display of cold hardy cactus and succulents along with native and drought-tolerant plants for many years now. It has also long been a resource for educating visitors on the importance of these plants, as well as the importance of water conservation through water efficient landscaping. So the mission statement isn’t necessarily a new direction, but rather an affirmation of what this garden has done so well for years. Few gardens are doing cold hardy, drought-tolerant plants at the level that Orton Botanical Garden is.

Many of the plants at Orton Botanical Garden are made available to the public for purchase through an annual plant sale in May, as well as through an online store. This is another great service because sourcing some of these plants is not easy, and this one of the few places they can be found for sale.

Wherever you live in the world, this is a garden that should be on your bucket list. Even at a mere 5 acres in size, one could easily spend hours exploring it, and each visit reveals something new. What follows is just a small sampling of the things you will find there.

Several species of buckwheats were in bloom, including this Railroad Canyon buckwheat (Eriogonum soliceps).

There were also quite a few penstemon species blooming, like this sidebells penstemon (Penstemon secundiflorus).

Podcast Review: Botanical Mystery Tour

My interest is piqued any time plants are featured or plugged in popular culture. Hence my ongoing series of posts, Botany in Popular Culture, featuring Futurama, Saga of the Swamp Thing, etc. Plants just don’t get enough airtime, so it must be celebrated when they do. Which is why I was excited to learn about Chicago Botanic Garden‘s new podcast, Botanical Mystery Tour, in which the plants referenced in pop culture take center stage.

The hosts, as they state in each episode’s introduction, “dive into the botany hidden in our favorite stories.” To help with the discussion, they bring in experts that work at Chicago Botanic Garden to explore the science (and fiction) behind the plant references. In addition to discussing pop culture and the related science, the guests share details about the work they do at the Garden and some of the research they are working on.

In the first episode, Jasmine and Erica ask Paul CaraDonna about the drone bees featured in an episode of Black Mirror. Since many bee species are in decline, will we have to resort to employing robot bees to pollinate plants that rely on bee-assisted pollination? A great discussion about native bees and colony collapse disorder ensues.

(But maybe the idea of autonomous drone insects isn’t too far-fetched…)

In episode two, the hosts ask why humans are so obsessed with corpse flowers. Thousands of people flock to botanical gardens to see these humongous, stinky flowers on the rare occasions they are in bloom, so what is so appealing about Amorphophallus titanum? Patti Vitt joins the discussion to share details about this fascinating plant.

A corpse flower in bloom is a brief and uncommon occurrence, reminiscent of the Sumatran Century Flower in The Simpsons and the 40 Year Orchid in Dennis the Menace.

 

The third episode features the sarlaccs of Star Wars. It turns out, sarlaccs are carnivorous plants. This discovery spawns an interesting discussion with horticulturist Tom Weaver about what defines a carnivorous plant and the various ways that different carnivorous plant species capture and kill their prey.

The fourth (and latest) episode is an exploration into the magical world of mushrooms. In Alice in Wonderland, Alice encounters a large, hookah-smoking caterpillar sitting atop a giant mushroom. Are there mushrooms big enough that a person could actually sit on them like Alice does? Greg Mueller joins the podcast to address this and many other mycology-based questions. The conversation includes a great discussion about why a botanical garden (whose main focus is plants) would be interested in fungus.

The discussions in this podcast are fun and enlightening. The hosts shine the spotlight on often overlooked characters in popular media, and with the help of their guests, lead captivating conversations about the science related to these characters. With only a handful of episodes available so far, it will be easy to get caught up. And then you, like me, will find yourself anxiously looking forward to embarking on another Botanical Mystery Tour.

The Dragon of Yankee Fork: Spalding Viaduct

This is a guest post by Martha Dalke Hindman. It is an excerpt from her upcoming book, The Dragon of Yankee Fork. This is the final of three posts. See also: Devil’s Washbasins and Grave Markers.

Travel with my Dad was always an adventure. However, the Spalding Viaduct on U.S. Highway 95, was the scariest stretch of concrete highway, we ever encountered.

Dad slowed to a stop as we approached the Spalding Viaduct. A semi tractor-trailer rig was traveling north and in the center of the viaduct, leaving no room for any other vehicles. I watched as the driver carefully drove his rig down the narrow span. The driver slowed, saluted his “thanks” to us, and continued his journey. Normal traffic, backed up at either end of the viaduct, continued to their destinations. Dad and I were on our way to Boise – Idaho’s Capitol City.

Dad continued the story about how the Spalding Viaduct on U.S. Highway 95 connects the State of Idaho, North to South and South to North.

“The Spalding Viaduct is the vital link for travelers to stay within the geographical boundaries of the State of Idaho. Otherwise, to reach Boise from Lewiston, travel west and south on U. S. Highway 12 to Walla Walla, Washington, cross the Columbia River south to Umatilla, Oregon Highway 82. Outside Umatilla, connect with U.S. Highway 84 east through Southeast Oregon, across the Snake River at Ontario, Oregon and into Boise. The only other way to reach Boise from our home in Moscow, is to travel south on U.S. Highway 95 to Lewiston, turn east on U.S. Highway 12 into Hamilton, Montana. From Hamilton, south on U.S. Highway 93 through the magnificent Bitterroot Valley, to the Montana, Idaho border. U.S. Highway 15 takes you to Idaho Falls and U.S. Highway 86 into Boise. Coming from our home in Moscow, travel time to Boise would be two days. That is why the Spalding Viaduct is so vital to North-South and South-North traffic.”

“Dad, do we change time zones before we reach Boise??”

“Yes, Martha Lee. Time zones change from Pacific Standard Time, to Mountain Standard Time when we cross the Salmon River Bridge at Riggins. Because we are traveling south, we lose one hour. Watch for a roadside park with a picnic table. Mother packed a lunch full of sandwiches, goodies and a thermos full of ice cold water. We should arrive in Boise about 7 pm. Mountain Standard Time. In the meantime, enjoy the scenery.”

“Dad, there is JUST the place for our picnic, under the shade of the black locust trees.”

We parked our car at the picnic area next to the Spalding Viaduct. The black locust trees in bloom, a gentle breeze brought “fishy” smells from the Clearwater River, the water still high and rapid from the spring rains. The log drive was finished, only a few pieces of debris floated by.

Several families were finishing their noon meal, as we sat down at the long wooden table and unpacked our lunch. Mother had prepared peanut butter and honey sandwiches, potato salad, liverwurst slices, cheddar cheese, carrots and strawberries from our garden, chocolate chip cookies, and a large Coleman thermos of cold water. What a feast!

The afternoon sun was warm, the breeze calm, just the recipe for a game of softball. Dad batted first. A gentle swing to left field. Home Run!!

My turn to bat! I swung, missing the first ball. The second pitch, I hit, but it flew straight into the Clearwater River. The strong current carried my softball downstream. I could not catch it. End of Game!

I cried. Dad put his strong arms around my sagging shoulders. “It’s OK, Martha Lee. I’ll see to it that you have another softball. We will never know how far your old ball will travel. It may get stuck in debris along the river banks, or it may end up in the Pacific Ocean, riding the ocean currents to the shores of the Hawaiian Islands, or maybe even into Shanghai Harbor, China!”

Several days later, Dad came home with a package under his arm. With a twinkle in his eye, Dad gave me the box. I opened the shiny, square box. Inside was a new softball ready to be played with and loved just as much as the old one.

Thanks, Dad.

Additional Information:

The Spalding Viaduct is falling apart, literally. Large pieces of the concrete columns become loose and fall to the ground. This once vital link on U.S. Highway 95 is closed with steel gates and a chain link fence. Moss grows where semi trucks carrying goods and produce South to North and North to South, passenger cars and buses, traveling South to Boise and North to Canada, watched out for each other on the narrow roadway.

Modern day travelers and truck traffic continues to travel North-South and South-North on U.S. Highway 95, over a new bridge (built in 1962) across the Clearwater River to the East of the Spalding Viaduct. A new stretch of highway was constructed from the river bridge, over the railroad tracks, up the hill, and onto the Camas Prairie. U.S. Highway 95 continues south to Grangeville, Riggins, and ends at Middleton, Idaho. U.S. Highway 44 connects with U.S. Highway 84 into Boise.

Updates were made to the current bridge in 2014. Click here for more information.

Introducing Herbology Hunt

This is a guest post by Jane Wilson.

———————

Many people are “plant blind”. They walk through areas of fantastic wildlife or just down their street without noticing what grows there. Even plants growing in the gutter have an interesting backstory.

The term “Plant Blindness” was first put forth by Wandersee and Schlusser in 1998. Without an appreciation of plants in the ecosystem, people will be less likely to support plant research and conservation.

Herbology Hunt was born out of a love of plants and wild places and a determination to get kids outdoors and really looking at their environment. One of the founders started Wildflower Hour on Twitter – a place for people to share photos of wildflowers found in Britain and Ireland – and from this was stemmed a children’s version, which became Herbology Hunt. The Herbology Hunt team put together spotter sheets for each month of the year. Each sheet includes five plants that can be found throughout the month. They were made available as a free download, so schools and individuals can print them for use on a plant hunt.

By the end of 2018, we had created a year’s worth of spotter sheets. We are now looking to promote their use throughout Great Britain. Eventually we want to reward children who find 50 of the plants with a free T-shirt, and we will be looking for sponsors to support this. We have been supported by the Botanical Society of Britain and Ireland and the Wild Flower Society who have made the monthly spotter sheets available. They can be downloaded here or here.

Herbology Hunt Spotter Sheet for January

The Wild Flower Society has a great offer for Juniors interested in plants – it costs £3 to join and you get a diary to record your finds.

Going outdoors and noticing wildlife has been shown in some scientific studies to improve cardio-vascular health and mental health. A herbology hunt must surely be a good thing to do with children to help them get into a better lifestyle that will benefit their future health. We hope that many families and schools will use our spotter sheets as a way to help children become more passionate about the environment and enjoy the benefits of being outdoors.

Check out the Wildflower Hour website for more information about Herbology Hunt, along with instructions on how to get involved in #wildflowerhour, plus links to social media accounts and the Wild Flower (Half) Hour podcast.
