The leaves can grow up to 200 mm long, and up to 150 mm wide. Mature stems sprout flowers with petals with yellow tones on top and green underneath.

Watermelons have an unfortunate legacy when it comes to race relations.
In a form of bitter irony, watermelons once symbolized an end to slavery before the American Civil War. The symbolism comes from how many free black people grew and sold watermelons as a source of income. After the war, white supremacist propaganda turned such symbolism into a racial stereotype.

Some farmers would also graft watermelons onto disease-resistant rootstocks for an increased protection against pests and diseases.
Bees can help watermelons grow better.
The US Department of Agriculture (USDA) recommends farmers to keep at least one beehive for every 4 km².

Watermelons with this condition have a symmetrical hole in place of the seeds at the center of their fruits. That said, hollow heart watermelons remain perfectly safe to eat.
Some Japanese farmers grow cube-shaped watermelons.
While you’d know watermelons as round fruits, they can also grow in many shapes and forms. In Japan, farmers grow different varieties of pyramidal, heart, or even face-shaped watermelons. To achieve this effect, growers would encase early sprouts into glass or metal boxes. As they grow, they assume the shape of the surrounding container.
Originally, the Japanese farmers came up with this method so they could stack and move the watermelons easier. However, the cost of growing watermelons in such a way turned their crop into a luxury good. Generally, cube-shaped watermelons can cost up to around $80 per kilo, compared to just around 60 cents for a kilo of regular watermelons. How’s that for neat watermelon facts?
