IdentificationCutleaf Coneflower can grow to 10 feet high (!), but in NC it is most often 4-7 feet. Leaves are large and cut into 5-11 lobes (or even twice cut). The heads are numerous in some plants but only a handful in others; rays are bright yellow and held horizontally to somewhat downward; the disk is green and over time becomes dome-shaped or conical. This is one of our most beautiful wildflowers, especially notable for the many flowers on such a tall herb and the strongly dissected leaves. Horticultural forms (mostly "double-flowered") are commonly planted in gardens, campuses, etc.
Taxonomic CommentsWeakley (2018) lists three varieties in the state -- the nominate var. laciniata, var. digitata, and var. humilis.

Other Common Name(s)Goldenglow is used for the horticultural forms. Green-headed Coneflower.
