Asimina


Pawpaw (Asimina) is a genus of eight species of small trees or shrubs with large simple leaves and large fruit, native to eastern North America. The genus includes the widespread common pawpaw Asimina triloba, which bears the largest edible fruit indigenous to the continent. Pawpaws are native to 26 states of the U.S. and to Ontario in Canada. The common pawpaw is a patch-forming (clonal) understory tree found in well-drained, deep, fertile bottomland and hilly upland habitat. Pawpaws are in the same plant family (Annonaceae) as the custard-apple, cherimoya, sweetsop, ylang-ylang and soursop; the genus is the only member of that family not confined to the tropics.
