A classic perennial, 'Moonbeam' is an excellent performer with bright lemon-yellow flowers produced in profusion from early through late summer. The airy clumps of fine, needle-like foliage on upright stems provide a  stong contrast to coarser leaved perennials. The colour of 'Moonbeam' compliments nearly every other plant in the garden. Coreopsis is one of the easiest perennials to maintain and is a good choice for beginners. The verticillata species is particularly long-lived, has a longer flowering time, and demonstrates better drought tolerance than others in the genus.
