Comments

Ethnobotany:The Seminole Indians used this plant to make a cleaning product and as a food source (fruits). Seeds are said to be toxic. The fruits have been used to make jelly and custard. Major pond apple forests along the southern rim of Lake Okeechobee were destroyed for agriculture early in the 20th century.
General Comments:In Australia, pond apple is a Weed of National Significance. It is regarded as one of the worst weeds in Australia because of invasiveness, potential for spread, and economic and environmental impacts.
