'Nana' is a spreading, dwarf coreopsis with mat-like foliage 6 to 9" tall consisting of dense, bushy, slowly-spreading clumps of broad-oval, shiny deep green leaves (to 1-3" long). Bright orange-yellow daisy-like flowers (1-2" diameter) with yellow rays (toothed at the tip) and yellow center disks appear singly on naked stems above the foliage in late spring to early summer. May sparsely rebloom throughout the summer into fall if spent flowers are regularly deadheaded. Good small area ground cover. Also effective as an edger for borders or walks and paths.
Grow in well-drained, slightly loamy soil in full to part sun. Plants tolerate some dry conditions, but are not as drought tolerant as most other species of Coreopsis. Prompt deadheading of spent flower stalks can be tedious for a large planting, but does tend to encourage additional bloom. In optimum growing conditions, plants will spread in the garden over time by stolons to form an attractive ground cover, but spread is easy to check.
