Yellow Waterlily

Nymphaea mexicana
native · Central Texas

Yellow Waterlily is a wildflower native to Central Texas that grows 0.5–1 ft tall and 2 ft wide. It wants full sun and high water. Blooms yellow in spring. Good for aquatic wildlife, birds and small mammals.

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.
