“7 Types of Giant Watermelons – Minneopa Or

Watermelons are such a delightful and refreshing summer staple – it seems almost too good to be true that we can grow these fruits in our own backyards.

Of course, there are so many incredible varieties to choose from, it can be very difficult to know which ones to pick.

I’ve made a list of 25 of the best watermelon cultivars – including picnic, icebox, personal-sized, and seedless varieties, as well as some with unexpected flesh colors.

Whether you’re in the mood for seed-spitting contests, juicy giants, sweet yellow babies, or something else entirely, I can practically guarantee that you’ll find exactly the watermelon variety you’re looking for in this roundup.

25 of the Best Watermelon Varieties

Picnic type cultivars are what most of us think of when we think of watermelon.

Whether oblong or round, the fruits weigh at least 15 pounds, but often more – enough to feed a small crowd during a summer gathering.

The big fruits on these cultivars mean they tend to require more growing time than others before they’ll be ready to harvest.

If you have a long growing season you can sow the seeds directly into your garden soil.

But if, like me, your summer gardening fun is typically foreshortened by early autumn frosts, you’ll probably need to start picnic type watermelons indoors and transplant them out to your garden after your last spring frost.

Read more about how to determine whether you should start seeds indoors or plant them directly in the garden.

Ready to dig into all the sweet and juicy details?

‘Allsweet’ has the classic look of a picnic watermelon variety.

With good disease resistance, it’s well-suited to long growing seasons.

With sweet, bright red, firm flesh, fruits will reach 17-19 inches long and seven inches in diameter at maturity.

Seeds are dark brown.

Also called ‘All Sweet’ this is an open-pollinated variety, so you can save the seeds from this year’s crop to grow next year’s melons.

Plants have a height of 15-24 inches, with vines spreading to 72-96 inches, and are resistant to fusarium wilt and anthracnose.

‘Charleston Gray’ is a distinguished heirloom variety producing large cylindrical fruit that have uniform greenish-gray skin.

Also sometimes referred to as ‘Charleston Grey,’ this open-pollinated picnic cultivar’s sweet red flesh is crisp and fiberless.

These often top out at 28 to 35 pounds each when they’re ready to harvest, so you better be ready to eat some watermelon this summer if you choose this type!

Plants reach a height of 15-24 inches and should be thinned to 36 inches apart, to allow for a spread of 72 to 96 inches.

This cultivar is resistant to fusarium wilt and anthracnose as well as sunburn.

Moving on from picnic to icebox type watermelons, we are moving down in size.

Icebox types grow to six to 15 pounds at full ripeness and can generally fit in the fridge, aka the “icebox.”

If you’re concerned about not being able to finish a whole picnic watermelon once you cut it open, these make a good alternative.

Another advantage to icebox types is that they tend to mature earlier than most picnic cultivars, so these are generally better choices for gardeners with a shorter growing season.

Or they can be grown alongside picnic varieties by gardeners who want to make sure they have an earlier crop to enjoy, as well as an abundance of fruit throughout the season.

Some of them also make better candidates for growing in raised beds since their vines can be (but aren’t always) shorter than those of picnic varieties.

If your climate tends to feel like an icebox at night, even in midsummer, ‘Blacktail Mountain’ may be your answer if you want to grow watermelons.

Developed in Northern Idaho, this is a short season open-pollinated cultivar that will tolerate cool nighttime temperatures.

‘Blacktail Mountain’ produces fruit that weigh six to 15 pounds, just the right size for storing in your fridge.

Fruits are round with a dark green rind and sweet scarlet-hued flesh.

And if your first frost comes early, fruits can be picked a little before full ripeness and ripened in storage, where they can keep for up to two months.

Wonderful for northern areas with cool nights and short growing seasons, this variety comes to maturity in just 70-75 days.

You’ll find certified organic and biodynamic ‘Blacktail Mountain’ seeds available for purchase in one-gram packets from Territorial Seeds via Arbico Organics.

Looking for a bush type watermelon that’s perfect for smaller gardens – or even for growing in containers?

‘Bush Sugar Baby’ produces an average of two 12-pound melons per plant, on “space-saving” vines.

This icebox type is small enough to store in the fridge, producing round dark green fruit with sweet scarlet flesh.

Plants grow to a height of 15-24 inches, with vines growing to be 3 1/2 feet long.

This variety has good resistance to cool weather, cracking, drought, and sunburn.

‘Bush Sugar Baby’ will be ready to harvest in around 80 days.

This space-saving icebox variety is available in packets of 40 seeds from Burpee.

‘Sweet Beauty’ is a hybrid variety with superior eating quality that was the All-America Selections winner in 2004.

A smaller icebox variety, these fruits weigh in at six to seven pounds.

Small oblong watermelons are striped with dark and light green.

Flesh is deep red with a sweet flavor and crisp texture.

The vines on this variety will spread eight to 10 feet and bear harvestable fruit in just 77-80 days.

You’ll find ‘Sweet Beauty’ seeds available for purchase in a choice of package sizes at True Leaf Market.

If you love watermelon but really wish you could harvest single-serving fruits, then personal type melons are going to make your day.

These cultivars weigh between three to six pounds, and are a delight to cut in half and eat with a spoon in one sitting.

Personal type watermelons are also a boon for those of us with short seasons and a risk of early frosts – they are the earliest to ripen.

And for those with long summer growing seasons or gardeners in warmer regions who have gotten their garden off to a late start, they will make a delicious early summer treat while you wait for your big picnic cultivars to ripen, or a juicy delight to enjoy come Labor Day. 10.

‘Golden Midget’ is a personal-sized watermelon variety that will really stand out in your melon patch – literally.

You’ll find ‘Golden Midget’ available for purchase in an assortment of packet sizes at Eden Brothers.

‘Little Darling’ is a small, early maturing hybrid watermelon variety that bears oblong, five to seven-pound fruit with dark green rinds.

These personal-sized fruits have a high sugar content, which means their red flesh is super sweet.

The vines of this early-maturing cultivar are compact at four to five feet long, producing melons that are ready to harvest in 65-70 days.

Expect three to four fruits per plant.

You’ll find ‘Little Darling’ seeds available for purchase in packs of 30 at Burpee.

Most of us have heard of gardeners growing giant pumpkins, but giant watermelons aren’t quite as common.

According to Guinness World Records, the largest watermelon ever grown weighed in at just over 350 pounds!

You don’t have to get quite that big for your melon to be considered a giant though.

Giant cultivars include those that weigh at least 32 pounds at full ripeness.

Keep in mind that you will certainly need a generous growing season in order for your watermelons to grow to such mammoth proportions.

If you’re going for whoppers, you’ll want to whittle down an excess of baby melons to allow the plants to focus their energies on just a couple.

Are you a fan of seedless watermelon?

Personally, I don’t mind seeds in my melons, but the seedless types do have a very useful purpose beyond the desire for a seedless slice.

When you’re using this fruit for culinary creations, such as sorbets or salads, seedless fruits are much more convenient than the seeded types since you get to skip the tedious step of removing those tiny pips from the flesh.

Growing these hybrids at home is doable, but it requires a bit more work and is a bit trickier than growing seeded types.

To start with, seedless varieties have a lower germination rate and because of this, they are often started as transplants instead of direct sowing.

In addition to lower chances of successful germination, seedless varieties must be planted with a pollinator plant (i.e. a seeded watermelon) nearby in order for seedless plants to produce fruit.

And this pollinator variety needs to bloom at the same time as the seedless cultivar.

So it’s a little extra work, but by no means a daunting gardening project.

If you’re the type of gardener who’s up for a bit of a challenge – and most importantly, one who prefers seedless watermelon – give it a try!

This seedless hybrid offers big flavor in a tiny package.

Topping out at six to eight pounds each, ‘Big Tasty’ melons reach about 10-12 inches in diameter when they’re ready for harvest.

Fruits are round or oval shaped with pale gray-green skins that hold crisp, firm, bright red flesh with stunning flavor.

This watermelon cultivar is known to keep its delicious flavor longer than other types after you cut into it, so it’s perfect for those with small households who know they might not be able to eat a whole melon all at once.

As a seedless variety, ‘Big Tasty’ will need to be planted with a seeded pollinator cultivar, such as ‘Gold in Gold.’

Plants reach a height of 15-24 inches with a spread of 60-72 inches.

Plants reach a height of 15-24 inches with a spread of 60-72 inches.

Expect a harvest in 85 days.

Expect a harvest in 85 days.

‘Mini Piccolo’ is a seedless hybrid variety that comes in a single-serving size.

These personal-sized watermelons have dense red flesh and are super sweet.

Plants are vigorous, producing up to six fruits each, and growing 14 inches tall with a 10-foot spread.

Make sure to plant ‘Mini Piccolo’ with a seeded pollinator variety, such as ‘Crimson Sweet.’

These melons will be ready to harvest in 80-83 days.

You’ll find ‘Mini Piccolo’ available for purchase in packs of 20 seeds at Burpee.

Don’t forget that this seedless type will need to be grown with a pollinator variety.

‘Bush Sugar Baby’ makes a good pollinator for ‘Triple Crown.’

High yielding plants will produce fruit that’s ready to harvest in 80 days.

You’ll find ‘Triple Crown’ seeds available for purchase in packs of 10 at Eden Brothers.

Orange, Yellow, and White Flesh

Orange, Yellow, and White Flesh

History of the Giant Watermelon

Gibson Sr. began holding a competition offering small prizes for the largest local fruits and vegetables.

In 1925, brothers Huge and Edgar Laseter sought to grow the largest watermelon, and Hugh brought home the title with a giant watermelon weighing in at 136 pounds.

The impressive watermelon was shipped to President Calvin Coolidge, where the presentation ceremony was broadcast on radio.

The giant watermelon brought lots of excitement to the area where the watermelon came from.

The first Hope Watermelon Festival took place the following year in 1926.

However, Hope was a small town, and the effects of the Great Depression directly impacted Hope’s ability to support such a large gathering each year and 1930 would be the last watermelon festival for nearly five decades.

Although it’s less show than before – the festival still draws plenty of competitors, eager to show off their own giant watermelon.

Many record-breaking watermelons have been displayed during the Hope Watermelon Festival, including a 268-pound giant watermelon that was recognized by the Guinness Book of Records in 2005.

Giant watermelon festivals have grown in popularity throughout the last century, with competitions often held at local state fairs or farms across the United States.

The current world record for the largest watermelon was set by Tennessee resident Chris Kent in 2013 – weighing in at a whopping 350.5 pounds!

So now that you know the history of giant watermelon contests, let’s get into some of the varieties of melons that you’ll find competing for first prize!
