Plant Preference/Growing Conditions: Plains coreopsis thrives in well-drained soils and prefers full sun exposure, which is essential for optimal growth and flowering. Its drought tolerance allows it to survive in less-than-ideal moisture conditions, making it suitable for a range of environments, including sandy and loamy soils.

Growth Habit/Description: Typically reaching heights of 1 to 3 feet, Plains Coreopsis exhibits a branching growth habit that results in a dense, bushy form. This structure not only provides visual interest but also creates a habitat for various insects and small wildlife.

Bloom Season: The bloom season generally spans from late spring to early summer, with the most prolific flowering occurring in June and July. This timing aligns with the peak activity of pollinators, ensuring that the plant plays a crucial role in supporting local ecosystems during this period.

Fall and/or Winter Interest? Yes, In the fall, the plant's seed heads remain intact, providing visual texture and attracting birds that feed on the seeds during winter. The plant's bushy structure continues to stand out in the landscape, even as the foliage fades, contributing to the garden's winter aesthetics.

Host Plant for Caterpillars?

Yes.  Fragrant sumac is a host plant for the red-banded hairstreak (Calycopis cecrops) and the spring azure (Celastrina ladon).

Other Known Ecological Value?

Yes.   Plains Coreopsis is an important nectar source for pollinators, including bees and butterflies, which are essential for the pollination of many plants. By attracting these species, it helps maintain the health and diversity of local ecosystems. The extensive root system of Plains Coreopsis plays a significant role in soil stabilization, helping to prevent erosion. This characteristic is particularly beneficial in areas prone to soil degradation.

Origin of Name:   The genus name "Coreopsis" is derived from the Greek words "koreos" (bug) and "opsis" (appearance), which refers to the flower's resemblance to a bug, highlighting its unique floral structure.

Related Plant Species:   Related species include Coreopsis lanceolata (Lanceleaf Coreopsis) and Coreopsis grandiflora (Large-flowered Coreopsis), both of which share similar growing conditions and ecological benefits.

Use For Food/Medicine:

While Plains Coreopsis is not commonly used for culinary purposes, but some Native American tribes have historically utilized parts of the plant for medicinal applications, although its primary value lies in its ornamental use and ecological contributions.
