Black Diamond watermelons are not seedless.
They’re a classic seeded variety, known for their sweet, crisp flesh and those familiar black seeds scattered throughout.
So if you’ve been asking, “are Black Diamond watermelons seedless,” the short answer is no.
These melons have been around for decades and are prized for their old-school flavor, not for being seedless.
In this post, we’ll dig into why Black Diamond watermelons aren’t seedless, what makes them special, and how to handle those seeds if you decide to grow or buy one.
Let’s get into it.
Why Black Diamond Watermelons Are Not Seedless
Black Diamond watermelons are not seedless, and here’s why:
1. They’re an Heirloom Variety
Black Diamond watermelons are an heirloom variety that dates back to the early 1900s.
Heirloom melons are open-pollinated, which means they produce seeds naturally.
Seedless watermelons, on the other hand, are a modern hybrid that requires special breeding techniques.
So because Black Diamond watermelons come from traditional seeds, they’ll always have seeds inside.
That’s just part of their genetic makeup.
2. Seedless Watermelons Are a Different Type Entirely
Seedless watermelons are created by crossing a diploid watermelon with a tetraploid one.
The result is a triploid plant that produces sterile fruit with tiny, white, undeveloped seeds.
Black Diamond watermelons don’t go through that process.
They’re a diploid variety, meaning they have two sets of chromosomes and produce fully formed black seeds.
So when you cut into a Black Diamond, you’ll see those seeds staring back at you.
3. The Seeds Are Part of the Experience
For many people, the seeds in a Black Diamond watermelon are part of the charm.
Spitting seeds on a hot summer day is a nostalgic tradition.
And those seeds are also what allow you to grow more Black Diamond watermelons year after year.
So while seedless melons are convenient, seeded ones like Black Diamond have their own appeal.
4. You Can Still Enjoy Them Without Eating the Seeds
Just because Black Diamond watermelons aren’t seedless doesn’t mean you can’t enjoy them.
You can easily scoop out the seeds with a spoon or cut around them.
Many people also blend the flesh and strain out the seeds for juice or smoothies.
So the seeds are there, but they’re not a dealbreaker.
What Makes Black Diamond Watermelons Special
Black Diamond watermelons are not seedless, but they’re still one of the most beloved varieties out there.
Here’s what sets them apart:
1. Exceptional Sweetness
Black Diamond watermelons are known for their deep, sugary flavor.
The flesh is firm, crisp, and bright red, with a sweetness that rivals any modern hybrid.
That’s why they’ve remained a favorite among gardeners and melon lovers for over a century.
2. Large Size
These melons can grow up to 50 pounds or more.
They’re not your average personal-sized watermelon.
A single Black Diamond can feed a crowd at a summer cookout.
So if you’re looking for a big, impressive melon, this is it.
3. Thick, Tough Rind
Black Diamond watermelons have a dark green rind that’s thick and durable.
That tough exterior makes them great for shipping and storing.
It also helps protect the fruit from pests and sunburn while it’s growing.
4. Great for Home Gardens
If you’re growing Black Diamond watermelons, you’ll get plenty of seeds to save for next season.
They’re open-pollinated, so the seeds will grow true to type.
That means you can keep planting them year after year without buying new seeds.
How to Deal With Seeds in Black Diamond Watermelons
Since Black Diamond watermelons are not seedless, you’ll need to deal with the seeds.
Here are a few easy ways to handle them:
1. Cut Around the Seeds
Slice the melon into wedges and use a knife to trim out the seed clusters.
The seeds tend to concentrate in the center, so it’s easy to avoid them.
2. Scoop Them Out
Cut the watermelon in half and use a spoon to scoop out the seeds.
This works well if you’re planning to cube the flesh for fruit salad.
3. Strain for Juice
Blend the flesh and pour it through a fine mesh strainer.
The juice will pass through, leaving the seeds behind.
4. Spit and Enjoy
Honestly, the simplest way is to just eat around them and spit the seeds out.
It’s messy, fun, and totally part of the experience.
So, Are Black Diamond Watermelons Seedless?
Black Diamond watermelons are not seedless.
They’re a seeded heirloom variety with a rich history and incredible flavor.
If you want a seedless watermelon, you’ll need to look for a hybrid variety instead.
But if you appreciate old-school taste, giant fruit, and the joy of spitting seeds, Black Diamond watermelons are hard to beat.
