Grow Native!

With the beginning of summer at our doorstep, many of us look out over our green grass yards and dread the coming heat that will endeavor to turn it brown and stale. One might begin to ponder if there is an alternative to these plants that fill our yards and demand so much of our water. In fact, there is.

Utah may be a desert, but not one naturally devoid of vegetation. Many plants have evolved to live within the bounds of the climate, insect pests, microbes and soil types specific to our region. Once established, many native plants need minimal irrigation beyond normal rainfall. And because they have coexisted for eons, natives have developed their own defenses against many pests and diseases, resulting in minimal pesticide use.

Backyards, gardens, parks, and roadsides planted with native plants also provide wildlife with a “bridge” to the natural areas that remain, interspersed among our heavily developed communities. As the cornerstone of biological diversity, native plants also do the best job of providing food and shelter for our local animals. Ready to get planting? Here are two natives that would be easy, attractive, and low-maintenance additions to many Utah yards or gardens.

Littleleaf Mock Orange is a compact shrub which produces clusters of wonderfully fragrant white blossoms. In the wilds of Utah, it is often found growing in rock crevices and dry, gravelly areas, so it will likely do well in those bare, difficult parts of your yard. It is browsed by mule deer and also provides shelter for native birds.

Fire Chalice, alternately known as hummingbird flower, is a low-profile plant with bright red tube-shaped flowers. The plant’s nectar is irresistible to hummingbirds and can help attract a number of native pollinators to your yard.

As with all plants, the right native must be matched with the right spot. Thankfully, there are native plants that thrive in every habitat imaginable. And the best thing is, natives include all different types of plants from mosses and ferns to wildflowers, shrubs and trees. A little bit of research should help you find the best species for your hot, dry slope, that wet swale in the back, or the dry shade under your trees.

For those interested in learning more, the Alterniscapes Garden Tour on June 25 provides an opportunity to view gardens in Millville, Nibley and Providence that feature water-wise and native plants.

Steershead & Turkeypeas

There is surprise and joy when discovering a flower peeking up at you from near the lingering snow. Long after winter weary eyes have devoured the early floral offerings of gardens here in the valley, our local natives are stirring higher up. As you wander thru mountain sagebrush and meadows, you may encounter scattered groups of two native wildflowers, Steershead and Turkeypeas. Both are a delight to the eyes, but difficult to find initially, as their diminutive nature keeps them hidden amid the surrounding plant litter.

Steershead, or Dicentra uniflora, lives up to its common name. A close cousin to the bleeding heart, it has four white to pinkish petals tinged light brown to purple, two of which are spurred. The longer pair bend back, while the shorter pair are fused at the tip, providing the “cow skull” appearance of the flower. Diminutive plants, they send forth leaves and a single flower from thickened, spindle-shaped tubers. Just a few inches tall, this small plant packs a lot of charm and a bit of poison for protection against plant eaters. Steershead occurrs singly or in small clusters, so it is easily overlooked.

Turkeypeas, Indian potato or Orogenia linearifolia, on the other hand, grows in extensive colonies, making this 4 inch tall plant a bit easier to find. A member of the carrot family, Turkeypeas produces very small whiteish flowers in umbels atop a short stem. Arising from a fleshy tuber, the leaves are divided into long linear segments (hence the name ‘linearifolia’). The starchy root is edible, though small, and historically was collected in large numbers by indigenous peoples in the spring. The tubers are avidly sought by squirrels.

So as the snow melts off the hillsides, look for these little darlings. Found only here in Western North America, I’m sure they will charm you as well.

When something is unique to a particular geographic area it is said to be endemic to that area. Not too long ago, while preparing for a lecture on Utah’s biodiversity, I was amazed to discover that Utah ranks sixth in the nation for its number of endemic species. Only Hawaii, California, Texas, Florida and Georgia have more. The Hawaiian islands are totally isolated –a factor that encourages endemics. California and Texas have enormous land area so I’m not surprised they have the space for more species to evolve. And Georgia and Florida are warm and wet states where you would expect biological richness! So what’s Utah doing so high on this list?

It turns out that our unique plants give us this high ranking. Utah has 2602 plants in all plus 393 subspecies or varieties. With 247 endemics Utah has an endemism rate of 8.2%. That’s pretty amazing.

Some areas of Utah have a lot more endemic plants than others. The Colorado Plateau in the south and east of Utah has the most. On the Plateau, erosion has exposed a long succession of different rock layers, and the rock has weathered into a patchwork of locally unique soils. Ecologists have found that isolated or peculiar soil types are like a nursery for endemics. Fine textured soils, saline soils or those that are highly alkaline are associated with highest levels of endemism.

Environmental extremes in the desert such as high temperature or low rainfall prompt evolutionary adaptations that eventually lead to speciation. For example, cushion plants are common on the Plateau—these are compact, low growing, mats often with large and deep tap roots adapted to slow growth in a nutrient- poor and water-restricted environment. In Utah deserts, many different buckwheat and milkvetch species adopted the cushion plant structure thus forming new species.

Variations in elevation can isolate species and create localized versions of widespread plants. High elevation areas can act as islands within the Colorado Plateau separating plants into distinct populations until they diverge over time. The La Sal, Abajo and Henry Mountains form mid-high elevation islands whose resident species are becoming more and more unique, forming endemics such as Chatterly onion, La Sal daisy, Cronquist’s buckwheat, Navajo Mountain penstemon, and Dwarf mountain butterweed.

We all know that Utah is a special place to live, but just knowing that our plants are so unique is another good reason to go out and explore.
