"Thread-Leaf Coreopsis is a native perennial in the daisy family that grows in dense bushy clumps. It may grow 2-3 feet tall with a similar spread. Plants thrive in infertile sandy and rocky soils and tolerate drought, low levels of salt, infertile soil, heat, and humidity.  If the soil is too rich or moist, stems become weak and plants tend to flop. The clumps will spread by rhizomes and can be divided every 2-3 years. It will also self-seed. Shearing the plant after blooming will sometimes produce fall flowers.

"This plant provides an airy appearance to the sunny border, naturalized area, native garden, or mass plantings. Its long bloom season provides a profusion of daisy-like yellow flowers. It is an easy-care plant that will give you years of enjoyment."  (North Carolina Extension)
