Like its sibling, coreopsis Moonbeam, rosea is a first rate plant for gardens across the country, developing scads of pink daisy blossoms on willow stems, bobbing gently in the breeze. Unlike Moonbean, rosea resides on the cool side of the color wheel, making it a fine companion for deep purples, blues and icy whites. Plant in groups of three or more and wonder how you did without it up to this point.
