Manyflower Marshpennywort

Hydrocotyle umbellata

native · Hill Country

Manyflower Marshpennywort is a perennial wildflower native to the Texas Hill Country that grows 0.5–1 ft tall and 20 ft wide. It wants full sun or part shade and medium water, and handles clay soil. Blooms white in Apr–Oct. Evergreen — it holds its leaves through winter. Good for aquatic wildlife.

Wet ground only. A wetland plant: it needs standing water or saturated soil — a pond edge, creek bank or rain garden, not a dry upland bed.
