In the same plant family as Paw Paw, although not hardy, Soursop is a tropical fruiting tree that needs warm temperatures and high humidity to thrive. It can be grown as a potted plant while its young but should be planted in the ground in a tropical zone if fruiting is desired as the tree can reach up to 25 tall. Soursop is a bushy, low-branching tree with 4 x 2 oval leaves. You can prune the central leader of the tree to create a full, dense specimen. Similar to Jaboticaba, the flowers and fruit emerge on the trunk and branches. The Soursop fruit is heart-shaped and covered with a spiny skin, and it often weighs up to 10 pounds or more. The inner pulp is soft and custard-like with a tart flavor.
