Blisterwort is a low-growing woodland wildflower that produces small yellow buttercup-like flowers from April through June. This shade-tolerant perennial forms modest clumps with deeply lobed leaves and thrives in partially shaded areas with average moisture.
In an HOA neighborhood

Works well in: backyard only.
