Discussion

Asimina pygmaea hybridizes with A. longifolia var. longifolia and A. reticulata, with backcrosses introducing various heights, larger and variously paler flowers, and degrees of fragrance grading from fetid in the maroon types to progressively more fragrant in the larger-flowered swarm components.
