Taxonomy

Subspecies

Cullen ''et al.'' (1995) recognises three subspecies, though scientific studies favor a more fine-grained separation: The subspecies cross easily, so that numerous intermediate forms can be found: their sweetness and tartness may vary, their colors varying from bluish-purple to red, orange, yellow or light green.
