Summary

Coreopsis grandiflora, commonly known as large-flowered tickseed, is a perennial herb native to the open woodlands, prairies, and roadside areas of the South Central and Southeastern USA. It typically grows to a height of 2-3 feet and a width of 1-2 feet, featuring bright yellow, daisy-like flowers with a darker central disk. The flowers bloom from early summer to fall, adding a long-lasting splash of color to the garden. Its upright stems and finely textured leaves add to its visual appeal.

Large-flowered tickseed is valued for its vibrant flowers and extended blooming period, making it a popular choice for borders, wildflower gardens, and as a cut flower. It is drought-tolerant once established, making it suitable for xeriscaping. This species thrives in full sun and requires well-drained soil. While it is generally easy to maintain, it can be susceptible to powdery mildew and root rot if overwatered or planted in poorly drained soils. Deadheading spent flowers can encourage reblooming and prevent excessive self-seeding.CC BY-SA 4.0
