Coreopsis 'Mercury Rising'
A very long-blooming perennial for sunny areas, forming a narrow, upright mound of medium-textured leaves. The exceptionally large velvety-wine daisies have a contrasting gold-orange button centre, appearing in succession from mid summer to mid autumn. Some flowers may appear frosted in creamy-white.
The flower backs are creamy-white with a purple stripe. Excellent towards the middle of a sunny border, also good in containers.
Plants may require some support if grown in very rich garden soil, or simply shear by half in July if they begin to flop open. Possibly hardy in Zone 4 or colder, with reliable winter snowcover.
