Mayhaw common in wetlands throughout the southern United States. Mayhaws grow in moist soil in river and creek bottoms under hardwood trees. The fruit ripens in late April through May, thus the name may-haw. The fruit is also found in bayous surrounding lakes, such as Caddo Lake on the Texas/Louisiana border. Mayhaws are often collected out of the water from boats, and the fruit is used to make jelly.
