Asimina parviflora, the smallflower pawpaw, is a small to medium shrub in the custard apple family.

Distribution

It is native to the Southeastern United States, where it is found from Texas to Virginia. It is found most often in sandy areas, alluvial areas, and dry woods.[2]

Description

Asimina parviflora has maroon, fleshy flowers in the spring. It produces an edible fruit, although the fruit is smaller than of its relative Asimina triloba, the pawpaw tree.[3]

Its pollen is shed as permanent tetrads. Small-flower pawpaws are found further south than common pawpaws, and form shrubs rather than trees, with most plants ranging in height from one to three feet, with only a few getting taller. The flowers are usually smaller than two centimeters in size. The flowers begin as brown buds, then swell to green immature flowers, and turn burgundy or brown when fully mature.

The leaves are usually a dark green, and smooth in texture.[4]

A. parviflora hybridizes readily with A. triloba to form Asimina ×piedmontana.[5]
