Citrullus Vulgaris

Watermelon fruit is very large, smooth, and oval to round. The skin can be solid green or green striped with yellow. The edible flesh is usually pink with many flat, oval, black seeds throughout. Seedless varieties also exist, as well as types with orange, yellow, or white flesh.

 

Watermelon grows as a vine that sends long runners along the ground. Watermelon leaves are dark green with prominent veins. They have three large lobes, each further divided into smaller lobes. Watermelon flowers are yellow, five-petaled flowers about an inch in diameter (smaller than some of the other vine fruits).  Watermelon vines, like squash, pumpkin, and cucumber, have separate male and female flowers on the same plant.
