American plum is not classified according to the maturity groups adopted for field crops. Agronomists focus on individual flowering times and the actual harvest period, which, depending on the ecotype and climate, spans from the second half of summer to early autumn.
Fruit maturity is determined organoleptically: by the ease of fruit detachment from the pedicel, a characteristic change in skin color to bright red or purple, and the appearance of slight shriveling. The prolonged ripening process often requires multiple harvests in commercial cultivation.
