Coreopsis verticillata 'Red Satin'

Thread-leaf Coreopsis

Plant Type: Perennial

Deep wine red to ruby red flowers with an orange center measure about 1 ½” across and completely cover the deep green, threadleaf foliage. Since the flowers are sterile, they appear over a long period from early through late summer and if cut back, the plants can be encouraged to rebloom until frost.

Compared to other threadleaf types, this plant has darker green foliage and is more clump forming, producing fewer rhizomes. Compared to ‘Mercury Rising’, this plant has finer threadleaf foliage, solid red flowers that do not become “frosted” in the heat, and a tighter mounding habit.

'Red Satin' has proven to be hardy to zone 5, a permanent threadleaf form as its series name suggests.
