The species, Coreopsis verticillata – (a.k.a Threadleaf coreopsis) pictured here, is an excellent choice for the sunny garden. Its foliage, like the common name Threadleaf coreopsis implies, is finely divided, bright green and forms a lacy backdrop for those happy brilliant yellow flowers.I love this plant because it’s easy, bright, and flowers over a long period of time if you give it a haircut mid-summer. To get the prolific flowering – plant this Coreopsis full sun (6 hours or more). You can go with part shade, but don’t expect to get the same flowering results. In the winter, even in our Mediterranean climate, Coreopsis verticillata tends to die back and resurface again in late winter/early spring. It’s a hardy plant, standing up to NYC winters.
