Phonetic Spelling:kor-ee-OP-sis ver-tik-il-LAY-tah

Genus:Coreopsis

Species:verticillata

Family:Asteraceae

Thread Leaf Coreopsis is a native perennial belonging to the daisy family, characterized by its dense, bushy growth habit. Typically reaching heights of 2 to 3 feet and spreading similarly, this plant flourishes in poor, sandy, and rocky soils, demonstrating resilience to drought, low salinity, heat, and humidity. However, if the soil is overly rich or moist, the stems may weaken, causing the plants to droop. The clumps can expand through rhizomes and should be divided every 2 to 3 years, while the plant also has the ability to self-seed. Pruning the plant after it blooms can occasionally encourage a second round of flowers in the fall.

This species adds a light, airy quality to sunny borders, naturalized areas, native gardens, or mass plantings. With an extended blooming period, it produces an abundance of daisy-like yellow flowers, making it a low-maintenance choice that promises years of enjoyment.
