Appearance

Paw paws have long, pear-shaped leaves with pointed tips. Leaves have fine, white hairs on top and rusty-colored hairs on the bottom. The leaves turn yellow in autumn. Small, maroon flowers with velvety petals bloom in April to May. Yellowish-green, mango-like fruits grow in September to October. The paw paw grows to 35 feet tall.

Reproduction and life cycle

Paw paws usually reproduce asexually when roots bud and form new shoots, which is why they often form small colonies. They can also reproduce sexually with fruits containing 10 to 14 brown, lima bean-shaped seeds that are spread by animals.
