Bigflower Pawpaw

Asimina obovata (Willd.) Nash

Comments

provided by eFloras
Taller strains of Asimina obovata , particularly those with pink or red inner petals, have great horticultural potential. W.Bartram figured this species adequately, but subsequent authors tended to confuse it and his somewhat similar Annona incana , with which it is sympatric in northern peninsular Florida.

Asimina obovata

provided by wikipedia EN

Asimina obovata, the bigflower pawpaw, is a shrub or small tree in the custard apple family. It is an endemic native[1] to Florida, where it is found on open sandy hammocks and in dry woods.[2] Showy white flowers in late winter to early summer are followed by large green edible fruit. Its pollen is shed as permanent tetrads.[3] Along with the other members of the genus, it serves as a host plant for zebra swallowtail butterfly and pawpaw sphinx moth[4]
