The pawpaw (Asimina triloba) belongs to Annonaceae (the Custard apple family). It is a semi-tall deciduous tree that is native to the temperate deciduous forests of eastern North America. This tree is often narrowly conical and can reach about 10 m in height. The leaves are alternate and spirally arranged, entire, obovate-lanceolate and 25-30 cm long. They turn rusty yellow in fall. The flowers are rich red-purple or maroon and bloom in early spring at the same time as or slightly before the new leaves appear. The fruit of the pawpaw is a large berry, 5-15 cm long with soft, edible fruit pulp. They are initially green, maturing by September or October to yellow or brown.
