The flowers of 'Solar Moon' are a lovely soft yellow with dark red eyes. Best grown in full sun, where it grows 20" tall and 18" wide. Blooms last a long time, beginning in early summer and lasting into the fall. A single specimen looks great, but a mass planting really puts on a show. It's a drought tolerant plant that is loved by pollinators. Hardy to Zone 4.
Pruning after flowering encourages a second flush of blooms.
