Learning how the fruit grows is very interesting. The tree produces flowers on long, woody stalks. These flowers have thick, yellowish petals. The fruit itself starts out as a dark green oval. It has a thick, leathery skin that you cannot eat. As the fruit matures, the skin turns yellow-green. The inside has white, juicy flesh. This pulp has a creamy texture like a banana. It smells like a pineapple. The taste is a mix of strawberry, apple, and sour citrus.
