Coreopsis

This appears to be one of the threadleaf coreopsis. Continuous blooming from early summer right into fall with full sun and well drained soil. Coreopsis verticillata are great cut flowers with its unusual narrow tapered foliage. Free flowering-continuously in bloom from early summer into fall. Spreads readily and can be used on a sunny bank, in a naturalized planting, or in a traditional border. Long blooming and easy to grow, they come in various heights and many shades of yellow, reds, pink, and white. Prefers a nice sunny well drained spot. Very easy to grow. Remove top one-third of plant with hedge shears after flowering to freshen foliage, if needed. Spreads reliably, so division every 2-3 years may be needed to restrain girth, but only if desired.
