Coreopsis tinctoria Plains coreopsis

Have you ever seen a field of bright yellow flowers along a highway or water bank? At first glance, you might think you’re looking at dandelions — but look again. If you see a bright maroon center surrounded by vibrant yellow petals, you’re looking at Plains Coreopsis.

The Plain Coreopsis flowers are popular for pasture beautification and pollinator gardens. These plants can thrive in different soil types and are moderately drought resistant. So, these hearty flowers can withstand a variety of climates.

If you’re interested in planting Plains Coreopsis in your wildflower garden, here’s everything you’ll need to know about the plant and how it grows.

What is Plains Coreopsis (Coreopsis tinctoria)?

Plains Coreopsis, also known as Golden Tickseed and Calliopsis, is a member of the Asteraceae family of flowers. Asteraceae flowers are known for their star-shaped flowering heads, giving Plains Coreopsis a striking similarity to other species like daisies. 

Plains Coreopsis thrives in disturbed land areas such as roadsides and ditches. It is widely cultivated in meadows, prairies, pastures, and pond banks. 

These beautiful wildflowers have red centers that expand outward into yellow petals, creating a stunning colorful blossom. It’s important to note that the red flower color displayed on Plains Coreopsis can vary. Some blooms may appear all yellow, and some may be distinctly maroon with a hint of yellow on the petals. 

Plains Coreopsis features long stalks that divide into multi-branching stems that will each bloom a flower head. The leaves grow up to one-fourth inch wide, six inches long, and have a pointed tip at the end. 

Coreopsis petals are notched-tipped, which means Plains Coreopsis has divots within the petal instead of a smooth round petal. This effect creates the appearance of “teeth” along the edge.

Growing Conditions for Plains Coreopsis

The Plains Coreopsis prefers full sun for optimal growth but can tolerate partial shade. These plants are native to the Great Plains but have adapted to other regions, such as the southern United States and Canada. 

You’ll want to plant Plains Coreopsis in the spring or fall season. This timing allows the seeds to germinate quickly and sprout with ample sun exposure before the summer and winter months. The vibrant yellow flowers will bloom from June to September. 

Plains Coreopsis can tolerate a wide variety of soil types, including moist soil and sandy soil. Where other plants may struggle in this sod, Calliopsis will thrive.

Benefits of Planting Plains Coreopsis

If you’re hoping to avoid deer and other wildlife entering your wildflower gardens, Plains Coreopsis is an excellent option for your fields. These plants are deer resistant, so animals will avoid them if they come looking for a snack. 

In the past, these native plants made yellow and red dyes. When the flowers are boiled, they produce a red beverage that soothes digestional discomfort. Additionally, Plains Coreopsis can be used to make root tea, a drink that helps upset stomachs. 

While Plains Coreopsis is deer resistant, these vibrant wildflowers will attract your local pollinators and insects. Bees, caterpillars, butterflies, and other insects will flock to your garden and feast on the nectar or foliage of the plant.

Special Considerations for Planting Plains Coreopsis

Generally speaking, Plains Coreopsis does not attract pests, deer, or other wildlife. However, the Calligrapha californica, or leaf beetle, feasts on this wildflower. This insect is sometimes called the Coreopsis beetle because of their fervent love for snacking on this plant.

Unfortunately, the leaf beetle will demolish growing Plains Coreopsis plants in an instant. The leaves will take on a skeleton-like appearance. If left untreated, the leaf beetle will continue the life cycle and lay eggs at the base of the plant. The following spring, you’ll discover that these young beetles have hatched and continued eating your Plains Coreopsis.

If you find leaf beetles or their larvae on your plants, immediately treat your flowers with an insecticide that kills pests. The sooner you treat your flowers, the better their chance of fighting back against the leaf beetle
