  • Approximate Mature Size: 24-60 in (61-152 cm) tall
  • Bloom Time: Summer
  • Sun Exposure: Full Sun to Full Shade

As you might have guessed from its name, Spreading Dogbane is a prolific grower, which is why you’ll find it widespread across both North America and Europe. It’s called “dogbane” because it is highly poisonous to dogs (and humans too).

Spreading Dogbane has small, pink bell-shaped flowers and a scent similar to lilac. Look for this pink wildflower in Wyoming in the sandy soil of streambanks.

Even though the large, pink clover-like blooms of Crown Vetch are beautiful, this plant is invasive in North America. Native to Europe, Asia, and Africa, Crown Vetch was introduced locally to be used as a groundcover in controlling soil erosion.

This pink wildflower grows in Wyoming on sunny, sandy banks where it can push out less hardy plants.

If you plant Crown Vetch on your property, choose an isolated location far away from flower gardens. Don’t forget to control its growth so it doesn’t spread to other areas and invade native species and ecosystems.

You’ve probably found Large Beardtongue if you see large, lavender tubular flowers growing on short upright stalks. Native bees, bumblebees, hummingbirds, and birds like to visit the showy blooms of this plant.

Large Beardtongue is a native pink wildflower in Wyoming and is also endemic, which means it only grows here.

True to its name, Fireweed is a resilient plant that will be the first to grow in clearings recently devastated by forest fires. In fact, Fireweed was seen growing throughout Washington State one year after Mount St. Helens erupted in 1980.

To find Fireweed, look for striking spikes of purplish-pink flowers covering a landscape. Hummingbirds, moths, and butterflies like to feed on this pink wildflower in Wyoming.

Deptford Pink is native to Europe, but this pink wildflower is a naturalized species in Wyoming. It grows so well that it can take over roadsides, ditches, and fields.

Although the nectar is attractive to butterflies, skippers, and bees, Deptford Pink is a self-pollinating plant that doesn’t rely much on these insects.

The Everlasting Pea is a frost-hardy vine that requires little care and grows like a weed when not controlled. It is native to Europe but has been naturalized in North America since the 1700s. Look for this pink wildflower in Wyoming on sunny banks with clay-rich soil.

The long tendrils and purplish-pink flowers of the Everlasting Pea look beautiful when climbing trellises or fences in your garden. You can also use it as a sprawling groundcover for banks and slopes.

Prairie Onion blooms look like floating balls of pink and white. Their flower clusters form on the end of long stalks that grow from tufts of leaves. Butterflies, in particular, are attracted to this pink wildflower in Wyoming.

Look for Prairie Onion where plants typically don’t grow, like sandy, rocky, and dry soils and limestone cliffs.

Like other allium varieties, you can eat the Prairie Onion! With a strong flavor, the bulbs and the flower stems can be eaten raw, boiled, pickled, or used as a seasoning for salads and soups. Native Americans and early settlers also used the bulbs to repel insects.
