Growing Zones
The lacy and finely-textured native Threadleaf Coreopsis (Coreopsis verticillata) is a perennial powerhouse known for its airy texture, golden yellow daisy-like blooms, and nonstop summer performance. Often called Whorled Tickseed or Thread-leaf Tickseed, this fine-foliaged beauty brightens borders, butterfly gardens, and rock gardens with masses of cheerful flowers from early to late summer.
This native perennial features slender, thread-like leaves that give the plant a light, feathery presence even when not in bloom. Its upright, clumping form stays tidy, typically reaching 1 to 3 feet tall and wide depending on the cultivar. The wiry stems hold abundant flower heads above the foliage, creating a floating effect that's simply enchanting.
In fall, the leaves may turn bronze-green or red, adding seasonal interest. Seed heads persist after blooming, feeding songbirds and adding winter texture.
It belongs to the Aster family and is native to the southeastern U.S. Threadleaf Coreopsis is a tough-as-nails prairie and meadow plant long cherished for its hardiness and cheerful blooms.
