26 Watermelon Varieties You Didn't Know Existed

If you've lived your life only eating classic striped watermelons with red flesh, you've been missing out on so many varieties. While you may not find out-of-the-ordinary watermelon types at your local grocery store, you should watch for them at the farmer's market. If all else fails, you can buy a package of seeds and plant a breed that intrigues you in your backyard. While we've included a 200-pound melon on our list, some are small enough to plant running up a trellis off the ground.

We've found 26 types of watermelon that you've likely never seen or heard of before. Their exteriors come in unusual shades from black to yellow and orange, with curious insides that range from white to yellow and orange. While most of these are easy to obtain as seeds, you may have to take a road trip to experience others at their natural source.

Although Black Diamond watermelons aren't a true black color on the outside, they're extremely dark green, which makes a striking contrast with their bright red flesh. These heirloom watermelons first came on the scene when Melville Dillon created them in Arkansas in the 1940s.

Black Diamonds tend to weigh somewhere between 35 and 100 pounds. So, you'll potentially need a lot of garden space and a few extra mouths to finish one off. The trick is to pick them the moment they're sweet without waiting until the middle is overripe. You'll know they're ripe when the bottom is pale yellow and the rest is dark green.

Bush Sugar Baby watermelons only grow to about 12 pounds on a 3.5-foot vine, which makes them a good candidate for small gardens and refrigerators. This variety is one of the sweetest watermelons around and has a delightfully crisp, smooth flesh. It only takes about 75 days for the fruit to ripen, so you can eat it only a couple of months after planting.

If you end up turning these into a dessert like watermelon sorbet or watermelon pie, it's probably not a bad idea to adjust the overall sugar content of the recipe since the fruit is so sweet. However, it's so tasty alone that you may not want to waste it on dessert.

Did you know some fruits can get sunburned? Luckily, Charleston Gray watermelons never have to worry about that because their grayish-green coloring protects them from the sun. As you may be able to guess from their name, they originated in Charleston, South Carolina. Charles Andrus developed this variety in 1954 while trying to create melons that were resistant to certain types of fungus and disease. So, these are tenacious fruits in more ways than one.

Charleston Grays are bright red on the inside, contrasting beautifully with their gray interiors. They weigh 25 to 35 pounds and delight watermelon lovers with their sweet flavor and crisp, fiberless texture.

Clay County Yellow Meat watermelons have their own festival. If you're anywhere near Ashland, Alabama, in August, you'll want to head down to the annual Clay County Alabama Yellow Meated Watermelon Festival. It features lots of these yellow beauties straight from the field, along with plenty of yellow-water-melon-themed goods.

These sweet melons first started delighting Alabama residents in the early 1900s. While they look like ordinary red-fleshed melons on the outside, a surprising orange-yellow-colored flesh and tan seeds await you on the inside. Despite being a different color, the taste is very similar to a classic red variety.

The Willhite Seed Watermelon breeders developed the Desert King watermelon in the 1960s. Being in Texas, they were trying to create a variety that could withstand the state's blistering sun and heat. While it does need water, the Desert King is more drought-tolerant than other types. Its light-colored rind is also sunburn resistant, and it prefers to grow in warmer soil (around 70 to 95 degrees Fahrenheit).

This mighty melon weighs in at 20 to 30 pounds and has a yellow-colored flesh that's nearly orange. Despite the light-colored skin and flesh, you can expect a juicy flavor that is reminiscent of your best memory of the fruit.

Golden midgets remind us of small yellow pumpkins on the outside. But, once you cut into them, you'll find a surprising salmon-colored interior that looks almost red against the gold. Golden Midget watermelons are only likely to get up to 3 pounds, so they're usually among the first ripe melons available.

Growing these can be a little difficult, as you have to watch that other animals don't plunder them before they're ready to pick. Sometimes, these end up nearly flavorless, while other times they end up sweet with a classic flavor. Regardless, they're juicy, crisp, and quite tasty.

Kaho watermelons are odd-looking and have small, elongated bodies and bright or light orange flesh that sets them apart. They only weigh 2 to 4 pounds each, so they're fun to split with a friend. This variety originated in China and made its way to Japan around 1912.

While Kahos are juicy, they're not overly sweet, except in hotter temperatures when the fruit sugars are especially high. They're a good candidate to grow on a trellis since they're only slightly larger than a big cucumber. Since they're so small and the skin is so thin, growing them off the ground will help protect them from hungry animals and pests.

You're not likely to find Lemon Drops for sale anywhere except at farmer's markets since the thin skins make them too fragile for shipping. In fact, they often split open on the vine, so they're quite finicky to grow.

Their name refers both to their bright yellow, lemon-like color and their flavor, which is sweet with a slight citrus undercurrent. One unique attribute of Lemon Drop watermelons is that their flavor extends from the yellow flesh through to the white of the inner rind. They're also only 1 to 2 pounds, so they're practically pre-portioned for an individual serving.

We love Moon and Stars watermelons because of their unique exterior. The overall coloring is dark (closer to blue than green), with a bright yellow spot like a full moon along with smaller yellow dots like stars. Peter Henderson & Co. sold the first Moon and Stars in 1926, and they have been delighting watermelon enthusiasts for almost 100 years. Although they appeared to be extinct in the 1970s, someone came across them near Macon, Missouri, in 1981. 

Beyond their gimmicky night sky exterior, they're also sweet and delicious. While the average size of these beauties is 20 pounds, they can reach over 40 pounds, giving consumer plenty to enjoy.

Orangeglo watermelons have a unique tropical flavor, which gives them the distinction of being one of the best-tasting orange-fleshed watermelons. Willhite Seed Co. first sold these beautiful wilt-and-insect-resistant watermelons sometime before 1965.

The exterior is light-green with dark green markings, and the name tells you what to expect when you cut open the fruit: glowing orange flesh. While they're usually a medium orange color, they range all the way to a fiery orange bordering on red. Orangeglos are crisp and sweet like Orange Crisps, but they contain a fair amount of white-colored seeds inside. Once fully grown, they reach a weight of about 25 pounds.

The Willhite Seed Co. created Royal Golden watermelons from the now-extinct Pumpkin Rind watermelon species. If we had been allowed to name this variety, we would have made sure the word "pumpkin" was in the name because of its resemblance to a glowing, yellowish-orange pumpkin. You probably couldn't turn these into jack-o'-lanterns, but they could easily fool you.

Imagine everyone's surprise when the lookalike turns out not to be a pumpkin! With its bright red flesh making a striking contrast against the golden outer shell, this is one special watermelon. These strange-looking fruits are sweet and filled with plenty of seeds, which can be annoying if you're used to seedless varieties.

Sugartown watermelon enthusiasts swear they're the best watermelons in existence, and people visit a small fruit stand in Sugartown, Louisiana, to snag them. Fans come from across the U.S. with some even buying large amounts to resell, and they even have been counterfeited. The stand tends to close for the season in mid-July after running out of melons, so don't make a long trek without knowing if it's open.

In an interview with WVUE, stand owner Jason Green says that one of the secrets to the success of the watermelon is that it grows in deep sand. The original stand owner, Corbett Gibson, remarks, "If you like honey, it's just as good as honey."

Yamato Silver watermelons are another variety from Japan, coming from the Nara Prefecture. If you have a chance to taste them, you're likely to detect citrus and pear notes with a hint of cream and may also find they remind you of honeydew melons.

Like most Japanese varieties, these are small, not overly sweet, and the perfect treat for a summer's day. Since they only weigh between 6 and 10 pounds, they're easy to store in your refrigerator to chill before you slice into them. However, you'll want to treat the fruit with care since the thin skin easily splits.
