What Is a Yellow Watermelon Called?
Watermelon with yellow fruit is called "Yellow Crimson Watermelon," although the scientific name, Citrullus lanatus, is the same as the red watermelon.
Ripen A Watermelon
Sweet, juicy watermelon (Citrullus lanatus) is pretty much synonymous with summer, though in warmer parts of the country it can be enjoyed year-round. Whether you're growing the fruit yourself or picking one up at your local grocery store or farmer's market, the key to getting the most out of this lusciously refreshing treat lies in choosing a watermelon at its peak of sweetness. Unlike cantaloupes and certain other fruits, watermelons do not continue to ripen after they are picked. It should be a creamy yellow instead of light green. The skin should be a little dull rather than glossy, bumpy rather than smooth and difficult or impervious to puncture with your thumbnail. Pick several melons up in your hands, one at a time. You can also thump the watermelon to see if it sounds ripe, but unless you are very familiar with how a ripe watermelon sounds, this probably won't tell you anything. Any longer and it will start to break down, developing an unpleasant texture.
