A watermelon is a large, oval fruit with green skin; sweet, juicy pulp; and seeds. Although red watermelons are the most common ones we see, they come in other colors, too, like orange, yellow and white. Watermelons are 92% water and related to cucumbers, squash and pumpkins.

The fruit is a round or oval watermelon with a firm, smooth rind that's typically green with darker marks or stripes. Depending on the cultivar, the fruit can range anywhere between 6 to 50 pounds, and in some rare instances, as much as 200 pounds. Each melon has sweet, juicy pulp that is red, pink, or even yellow.

Watermelons grow on vines that spread along the ground. The leaves are large with deeply notched edges. The small flowers are yellow and grow in the crook between the leaf and the stem. Each flower on a watermelon vine produces either pollen or fruit.
