13 Watermelon Varieties (Different Types and Varieties)

Sliced watermelon, close up.

Horticulturists and farmers in this country have generated hundreds of watermelon cultivars throughout the years. As a result, there are over 50 different types of watermelon, the bulk of which you may never have seen before. They differ substantially in color, texture, and flavor.

You’ve come to the right site if you’re seeking the best kinds of watermelon to grow in your yard. We’ll go over the best watermelon varietals in this guide. We’ll go over the four different watermelon classifications and give brief descriptions of the most common watermelon types under each one to make things easier.

Seedless Watermelons

For those of you who don’t enjoy spitting melon seed, seedless watermelons were developed in the 1990s. Successive breeding has finally produced a melon that is as delicious as seeded varieties, although it hasn’t improved poor seed germination significantly. It’s a little more difficult to grow seedless varieties than it is to simply plant a seed and wait for it to sprout. The seed must be kept at a steady temperature of 90 degrees F (32 degrees C) until it emerges.

Seedless watermelons have been around for almost 50 years and have few or no seeds. We’re talking about developed seeds, the black ones when we say seeds. White seed coatings that have not matured are frequently mistaken for seeds. This, however, is not the case! They’re absolutely safe to ingest while eating, and there’s no need to worry about seeds growing in your stomach.

Chromosomes are the genetic building elements that give living things like plants and watermelons their characteristics or attributes. Watermelon breeders discovered that crossing a diploid (two sets of chromosomes) plant with a tetraploid (four sets of chromosomes) plant creates a fruit that generates a triploid seed. (It does, after all, have three sets of chromosomes.) The triploid seed that yields seedless watermelons is this one!

In other terms, seedless watermelon is a sterile hybrid generated by mixing male watermelon pollen (which has 22 chromosomes per cell) with female watermelon blossom pollen (which has 44 chromosomes per cell). The little, white seed coats inside this seeded fruit contain 33 chromosomes, rendering it sterile and incapable of generating seeds when it grows. This is related to the mule, which is created when a horse and a donkey are crossed. This procedure does not entail any genetic tinkering.

Seedless watermelon varieties include:

Big Tasty

This seedless hybrid packs a lot of flavor into a small container. When ready for harvest, ‘Big Tasty’ melons attain a diameter of about 10-12 inches and weigh up to six to eight pounds each. Fruits are round or oval in shape, with pale gray-green skins and crisp, firm, brilliant red flesh that has a delicious flavor. In fact, when compared to over 50 other types, this variety won Burpee’s taste test.

This watermelon cultivar is noted for keeping its excellent flavor after cutting into it for longer than other sorts, making it ideal for individuals with small households who know they won’t be able to devour the entire melon at once.

Because ‘Big Tasty’ is a seedless variety, it will need to be pollinated with a seeded pollinator cultivar like ‘Gold in Gold.’ Plants grow to be 15-24 inches tall with a 60-72 inch spread. In 85 days, you can expect a harvest.

Triple Crown

‘Triple Crown’ watermelons are large enough for a picnic. The word “triple” in the name of this cultivar refers to the fact that it is a triploid or seedless hybrid.

Fruits are oval in shape and weigh 18-20 pounds, with light green rinds and dark green stripes. This variety’s fruits have a fine-grained texture and a rich crimson, luscious, firm flesh.

Remember that this seedless variety will necessitate the use of a pollinator variety. The pollinator for ‘Triple Crown’ is ‘Bush Sugar Baby.’ Fruit from high-yielding plants will be ready to harvest in 80 days.

Mini Piccolo

The seedless hybrid variety ‘Mini Piccolo’ comes in a single-serving size. Green rinds with darker green patterning cover round fruits that weigh two to four pounds. The flesh of these small watermelons is thick red and extremely tasty.

Plants grow 14 inches tall with a 10-foot spread and produce up to six fruits per plant. Plant ‘Mini Piccolo’ with a seeded pollinator variety like ‘Crimson Sweet.’ In 80-83 days, these melons will be ready to harvest.

Icebox Watermelons

Icebox watermelons are smaller than their counterparts, weighing 5 to 15 pounds, and are bred to feed one person or a small family (2-7 kg.). This category includes the following watermelon plant varieties:

Bush Sugar Baby

Looking for a bush watermelon that’s ideal for compact areas or even container gardening?

We’ve got your back. On “space-saving” vines, ‘Bush Sugar Baby’ produces an average of two 12-pound melons per plant. This icebox variety produces oval dark green fruits with sweet crimson flesh that can be stored in the refrigerator.

Blacktail Mountain

This short-season open-pollinated cultivar was developed in Northern Idaho and can withstand low nighttime temperatures.

Fruit from ‘Blacktail Mountain’ weighs six to fifteen pounds, making it ideal for storage in the refrigerator. The spherical fruits have a dark green exterior and tasty scarlet-colored flesh.

Plants reach a height of 15-24 inches, with vines reaching a length of 3 1/2 feet. Cool temperatures, cracking, drought, and sunburn are all resistant to this cultivar. In about 80 days, ‘Bush Sugar Baby’ will be ready to harvest.

Sweet Beauty

‘Sweet Beauty’ is a high-quality hybrid cultivar that won the All-America Selections award in 2004. These fruits are a smaller icebox kind, weighing six to seven pounds.

Small oblong watermelons with dark and light green stripes. The flesh is a dark crimson color with a sweet taste and a crisp texture. This variety’s vines will extend eight to ten feet and deliver fruit in as little as 77-80 days.

Picnic Watermelons

Another watermelon variety, the Picnic, is larger, ranging from 16 to 45 pounds (7-20 kg) or more, making it ideal for a picnic. These are the classic oblong or spherical melons with a green rind and sweet, crimson flesh, which take around 85 days to mature. Here are a few examples:

Charleston Gray

The heirloom cultivar ‘Charleston Gray’ produces enormous cylindrical fruits with a consistent greenish-gray skin. The sweet red flesh of this open-pollinated picnic variety, sometimes known as ‘Charleston Grey,’ is crisp and fiberless. The firm rinds of the fruits make them excellent keepers.

When ready to harvest, they can weigh up to 35 pounds each, so be prepared to eat a lot of watermelons this summer if you choose this kind!

Plants should be trimmed to 36 inches apart when they reach a height of 15-24 inches, allowing for a spread of 72 to 96 inches. This cultivar is resistant to sunburn, fusarium wilt, and anthracnose. In 85 days, you can expect a harvest.

Allsweet

‘Allsweet’ has the traditional appearance of a picnic watermelon. It’s well-suited to long growing seasons due to its disease tolerance.

This cultivar produces enormous oblong fruits with dark and light green striped skin that weigh 25-30 pounds per. At maturity, the fruits will be 17-19 inches long and seven inches in diameter, with tasty, bright red, firm flesh. The seeds are a dark brown color.

This type, also known as ‘All Sweet,’ is open-pollinated, which means you may preserve the seeds from this year’s crop to grow next year’s melons.

Plants reach 15-24 inches in height, with vines reaching 72-96 inches in length, and are resistant to fusarium wilt and anthracnose. After seeding, ‘Allsweet’ will be available to harvest in 90-104 days.

Crimson Sweet

‘Crimson Sweet’ is a delicious, productive, and disease-resistant open-pollinated picnic-type heirloom variety that remains a favorite among many gardeners. This huge, round cultivar has pale green skin with dark green stripes and weighs roughly 25-35 pounds when harvested.

The flesh of this watermelon is dark crimson, solid, and finely textured, with little dark seeds. The high sugar content of ‘Crimson Sweet’ contributes to its delectable sweet flavor. Fruits have thick rinds that withstand handling well.

Plants are strong and resistant to anthracnose and fusarium wilt, reaching heights of 15-24 inches with a spread of six to eight feet. In 80 days, you’ll be able to harvest these luscious, juicy melons.

Yellow/Orange Watermelon

Finally, yellow/orange-skinned watermelon plant variants, which are normally round and can be seedless or seeded, are discussed. As you may expect, the color of the flesh varies depending on the variety. In around 75 days, these melons will be ready to eat. Among the varieties are:

Orangeglo

The orange flesh of ‘Orangeglo’ has the crisp, refreshing mouthfeel of a conventional watermelon, but it has a surprise, tropical flavor. The vivid orange flesh of this open-pollinated cultivar is extremely sweet with hints of exotic fruit aromas.

The seeds of ‘Orangeglo’ are also uncommon, being whitish with two brown spots at the tips. When fully ripe, the fruits are oblong, bright green with green stripes, and weigh 20-30 pounds. The rinds are pretty thin, so if you slice one of these melons with a knife, it will easily crack open.

The Willhite Seed Company in Poolville, Texas, developed this picnic variety in the 1960s, yet despite its southern roots, it thrives in northern regions and is cold tolerant. The plants produce a lot of fruit and are resistant to wilt and insect problems. On the vine, the fruits are resistant to splitting. In 90-100 days, you’ll be able to harvest ‘Orangeglo.’

Mountain Sweet Yellow

This is an open-pollinated, yellow-fleshed heirloom variety derived from ‘Mountain Sweet,’ a red-fleshed cultivar popular in the Northeast during the 1800s.

When fully mature, these oblong picnic-style watermelons weigh 20-35 pounds. The flesh is rich yellow with black seeds, and the rins are dark green with light green stripes.

The high sugar content of ‘Mountain Sweet Yellow’ will keep you going back for more of its juicy, crisp, sweet yellow flesh. The vines will grow to a height of six to ten feet, with fruit ready to harvest in 95-100 days.

Orange Crisp

If you don’t want to spit or pick off pips, this orange-fleshed picnic type has a further benefit. Orange Crisp is a watermelon hybrid with sweet, crisp, deep orange flesh that is free of bothersome seeds.

When fully ripe, the fruits are 11 inches in diameter, weigh 17-19 pounds, and are round to oval in shape. ‘Orange Crisp’ features a thick, light green rind with darker green stripes that keeps up well in storage.

Large quantities of fruits produced by plants are highly resistant to sunburn and hollow heart. Remember to pair seedless ‘Orange Crisp’ with a pollinator cultivar like ‘Charleston Gray.’ These orange-fleshed beauties should be ready to harvest in around 87 days.

Conclusion
