Plains Coreopsis

Plains coreopsis (Coreopsis tinctoria), also known as golden tickseed or calliopsis, is a species of flowering plant in the Asteraceae family, native to the United States and Canada. It is a popular plant in gardens and landscapes due to its vibrant colors and ease of care. This annual or short-lived perennial is known for its striking yellow and maroon flowers, which bloom from early summer to fall, attracting pollinators such as bees, butterflies, and other beneficial insects.

Description

Plains coreopsis grows to a height of 1 to 3 feet and features slender, branched stems. Its leaves are opposite, lanceolate to linear, and sometimes lobed. The flowers are typically 1 to 2 inches in diameter, with yellow rays and maroon to brownish centers. These are borne on long peduncles and form a showy, daisy-like inflorescence.

Habitat and Distribution

Originally from the plains and open prairies of North America, Coreopsis tinctoria has adapted to a wide range of habitats. It prefers full sun and can thrive in various soil types, from moist to dry conditions, making it a versatile plant for different garden settings. Its native range extends from the southern United States to northern Mexico, but it has been widely naturalized in other parts of the world due to its ornamental value.

Cultivation and Uses

Plains coreopsis is easy to grow from seed and often used in wildflower mixes, borders, and as a cut flower due to its long vase life. It is drought-tolerant once established, making it a suitable choice for xeriscaping and low-maintenance gardens. In addition to its ornamental use, Coreopsis tinctoria is also planted for soil erosion control and as a cover crop in agricultural settings.

Varieties and Hybrids

There are several cultivars and hybrids of Coreopsis tinctoria that vary in height, flower color, and bloom time. Some popular varieties include 'Roulette', which has mahogany-red flowers with a golden edge, and 'Mahogany Midget', a dwarf variety that grows only about a foot tall.

Conservation

While Plains coreopsis is not currently listed as endangered, its habitat is threatened by urbanization, agriculture, and climate change. Conservation efforts are focused on preserving natural habitats and promoting the use of native plants in landscaping to support biodiversity.
