Coreopsis verticillata (Threadleaf Coreopsis, Whorled Tickseed)

Threadleaf Coreopsis, with its showy flower clusters and airy foliage, is as popular in the garden today as it was in the 19th century. Its natural habitat,* though, is mostly in Virginia and central North Carolina. If you are fond of its appearance but wary of self seeding plants, then try the sterile, compact cultivar ‘Moonbeam’ that spreads by rhizomes.

*It also is native to DC and to areas in MD. It is unreported in DE and PA.
