As drought and threats of drought continue in the western half of the United States, as well as in many other parts of the world, people are increasingly looking for ways to use less water in their landscapes. For many it is a change they are reluctant to make, worried that they will have to sacrifice lush and colorful yards and gardens for drab, dry, gray, and seemingly lifeless ones. Not so, though. The palette of plants that can survive in low water environments is actually quite diverse and contains numerous plants that are just as lush and colorful as some water hogging ones. If planned, planted, and maintained well, a water efficient garden can be incredibly attractive and can even consist of some plants that are comparatively more heavy water users. So, for those who are apprehensive about getting down with brown, don’t fret – there is a better way.
How does one go about creating such a garden? The answer to that is a book on its own – much too long for a single blog post. It also depends who is asking the question, or more specifically, where they are asking it from. Luckily, demonstrations of water-wise gardens are becoming more common. These gardens, planted with regionally appropriate plants and showcasing various water-saving techniques, are great places to start when looking for ideas and motivation. Such gardens can be found at public parks, city and state government buildings, botanical gardens, nurseries and nursery centers, and water company offices. If you are looking to transform your landscape into a more water efficient one, seek out a demonstration garden in your area. It’s a great place to start.
There are several such gardens where I live, one of which is the Water Efficient Garden at the Idaho State Capitol Building in Boise, Idaho. This garden began in 2010 as a partnership between United Water Idaho and the Idaho Capitol Commission. Its mission is to introduce visitors to “low-water native and adaptive plants that thrive in Idaho’s climate.” The plants that were selected for the garden are commonly found at local garden centers and nurseries – an important objective when introducing people to water-wise gardening. The ultimate goal of this garden is to “show homeowners that they can maintain attractive landscaping while conserving water.”
I have my criticisms of this garden regarding plant selection, design, etc., but I’ll spare you those details. I also don’t know the specifics about how this garden is maintained or how often it is watered. All that aside, I am just happy that it exists, and I encourage you to seek out similar gardens in your area. There are numerous approaches to designing and constructing water efficient gardens – again, a book on its own – but demonstration gardens like this are an excellent place to get ideas and learn what other people in your area are doing to conserve water and create landscapes that better reflect the ecology of your region.
United Water Idaho offers a brief introduction to low water gardening here, as well as a list of plants that are in the capitol building garden here.
Blanket flower (Gaillardia x grandiflora ‘Goblin’). Plants in the garden are accompanied by a sign with a number on it. The sign corresponds to a plant list that is provided at the entrances to the garden.
A drift of pearly everlasting (Anaphalis margaritacea)
Purple coneflower (Echinacea purpurea)
Yellow ice plant (Delosperma nubiginum)
