With large, canary-yellow shining petals, these globe-shaped flowers glow in the mid-spring garden perched over glossy, divided leaves. Plant in a boggy spot, or near a stream or water feature that has a damp edge. The more sun, the more water it will need and heavy soils are okay. 16" T, clumping.
Minimum temperature: -40° F
