Hello, fellow adventurers of the soil! It’s Patricia here.
There’s a certain magic that comes with gardening, a connection to the earth that’s both grounding and thrilling. For me, the biggest thrill comes from discovering weird vegetables to grow that push the boundaries of the typical vegetable patch.
While I have a deep love for a classic, sun-ripened tomato, my heart truly sings when I discover a plant that makes me stop and say, “What in the world is that?”
If you’ve ever felt that pull towards the peculiar, you’re in the right place. We’re about to go on a journey beyond the familiar rows of carrots and lettuce into a world of fractal-patterned florets, watermelon imposters, and beans that defy belief.
These aren’t just botanical oddities; they are delicious, nutritious, and surprisingly achievable for the home gardener. This guide is your invitation to experiment and add a splash of unexpected color and flavor to your plots and plates.
We'll cover everything you need to know—from what they are to how to grow them and, most importantly, how to enjoy them. So, grab your trowel, and let’s get weird!
1. Romanesco: The Mind-Bending Fractal Vegetable
The first time you see a Romanesco, it feels like you’re looking at something not of this world. Its florets grow in a perfect, mesmerizing spiral—a natural example of a fractal.
This stunning chartreuse vegetable isn't a modern creation; it’s a treasured Italian heirloom vegetable dating back to the 16th century.
What Does Romanesco Taste Like?
The flavor is a delightful surprise! It’s much milder and sweeter than a typical cauliflower, with a nutty, almost earthy taste. The texture is another win; it’s incredibly tender with a satisfying crunch. It completely lacks the slight bitterness that can sometimes accompany its more common cousins.
How to Grow Romanesco
This cool-weather crop thrives in conditions similar to broccoli and cauliflower.
- Soil: Use rich, well-draining soil with plenty of compost mixed in. A pH between 6.0 and 7.0 is ideal.
- Sun: Full sun is best, but it will tolerate a little afternoon shade, especially in warmer zones.
- Care: Consistent watering is key. Give them about an inch to an inch and a half of water per week to prevent premature heading.
Start seeds indoors about 4-6 weeks before your last spring frost, or plant them for a fall harvest. Give each plant about 18-24 inches of space.
Cooking with Romanesco
Don't overcomplicate this beauty. My favorite way to prepare Romanesco is to roast it with olive oil, garlic, salt, and pepper at 400°F (200°C) until the edges are golden. It’s also fantastic lightly steamed or even shaved raw into a winter salad.
2. Cucamelons: Tiny Watermelon Lookalikes
Prepare to be utterly charmed. Cucamelons (Melothria scabra) are grape-sized fruits that look exactly like miniature watermelons but taste nothing like them.
These prolific climbers are native to Mexico and Central America and are a joy to grow, especially if you have children who love to forage in the garden.
What Do Cucamelons Taste Like?
Pop one in your mouth for a burst of fresh, cucumber-like flavor with a distinct, tangy, lime-like finish. The skin provides a pleasant snap, making them incredibly refreshing on a hot summer day.
How to Grow Cucamelons
Don’t let their exotic nature fool you; these unique garden plants are surprisingly easy to grow and are more pest-resistant than many cucumber varieties.
- Soil: They aren’t too fussy but prefer well-draining, fertile soil.
- Sun: Give them a spot with at least six hours of direct sunlight.
- Care: As vigorous vines, they need a trellis, cage, or fence to climb. This keeps the fruit off the ground and makes harvesting a breeze.
You can harvest them when they are firm and about the size of a grape. Don't let them get too big, or they can become seedy and sour.
How to Use Cucamelons
Cucamelons are a perfect snack straight off the vine. They also add a surprising crunch to salads, can be dropped into a gin and tonic, and make fantastic pickles.
3. Purple Carrots: The Antioxidant-Rich Ancient Root
Before the Dutch famously cultivated the orange carrot, carrots came in a rainbow of colors—most commonly purple and yellow. Are purple carrots natural? Absolutely! They are the original model.
Growing these striking roots is like planting a piece of history in your garden bed.
What Do Purple Carrots Taste Like?
Purple carrots often have a similar sweetness to their orange counterparts but with a subtle, peppery, almost spicy undertone that is incredibly satisfying.
How to Grow Purple Carrots
Growing purple carrots is identical to growing any other carrot. The key is loose, obstruction-free soil.
- Soil: Deep, loose, sandy loam is the holy grail. Avoid rocky or heavy clay soil.
- Sun: Full sun is necessary for strong root development.
- Care: Keep the soil consistently moist. Thin your seedlings diligently to give each root enough room to bulk up—about 2-3 inches apart.
Sow seeds directly into the garden from mid-spring. The deep purple color comes from anthocyanins, the same powerful antioxidant found in blueberries.
How to Use Purple Carrots in the Kitchen
Roasting brings out their sweetness beautifully. They are also fantastic shredded raw into slaws and salads. Be aware that boiling them can cause the purple color to bleed, so steaming or roasting is usually a better bet.
4. Kohlrabi: An Easy-to-Grow Alien Vegetable
Kohlrabi looks like a spaceship landed in your garden. This odd-looking orb from the brassica family is actually a swollen stem, not a root. It's a staple in German cuisine and is one of the most beginner-friendly weird vegetables to grow.
What Does Kohlrabi Taste Like?
When eaten raw, Kohlrabi is magnificently crisp, juicy, and mildly sweet, with a texture similar to a broccoli stem. Cooked, it becomes tender and takes on a delicate, sweet flavor. It's arguably at its best when eaten raw.
How to Grow Kohlrabi
This is a fast-growing, cool-season vegetable perfect for both spring and fall gardens.
- Soil: It does best in fertile, well-drained soil.
- Sun: Provide at least six hours of full sun.
- Care: Consistent moisture is vital to prevent the bulb from becoming woody. Harvest them when the bulbs are about 2-3 inches in diameter.
Plant seeds directly in the garden a few weeks before your last frost date. The leaves are also edible and can be cooked like kale or collard greens!
Ways to Eat Kohlrabi
For a refreshing snack, peel the bulb and slice it into sticks to eat raw with hummus. It also makes a fantastic, crunchy slaw or can be roasted with other root vegetables.
5. Yardlong Beans: Impressive Three-Foot-Long Pods
If you're looking for a garden showstopper, look no further. Yardlong beans, also known as asparagus beans, are a tropical vine that produces pods that can reach up to three feet in length.
What Do Yardlong Beans Taste Like?
Despite their name, they don't taste much like asparagus. Their flavor is less "beany" than a typical green bean and has a slightly nutty, complex taste. Their texture holds up well when cooked.
How to Grow Yardlong Beans
As a subtropical plant, these beans absolutely adore heat. Don't plant them until the soil is thoroughly warm.
- Soil: They thrive in average to fertile, well-draining soil.
- Sun: Full, blistering sun is their best friend.
- Care: You must provide a very sturdy, tall trellis—at least 6-7 feet high. Harvest the pods when they are about 12-18 inches long for the best flavor.
How to Cook Yardlong Beans
Yardlong beans are a star in Asian cuisine. They are fantastic chopped into segments and thrown into a high-heat stir-fry with garlic, ginger, and soy sauce.
6. Mouse Melons: A Quirky Vine for Small Gardens
If cucamelons are charming, mouse melons are downright adorable. These are one of the most unique vegetables for container gardens due to their delicate vines.
A Word of Caution: The ripe, dark-black fruits are a powerful laxative. Harvest them while they are still light green!
What Do Mouse Melons Taste Like?
The unripe green fruits have a crunchy texture and taste like a slightly tangy, "greener" cucumber. They are a fun, pop-in-your-mouth treat.
How to Grow Mouse Melons
These are wonderfully low-maintenance and are happy to scramble up a small trellis or even spill over the side of a hanging basket.
- Soil: They are not demanding and will grow in most garden soils.
- Sun: Full sun to partial shade.
- Care: Provide something for them to climb on. Water them regularly and harvest frequently.
Using Mouse Melons
Use them just as you would a cucamelon. Toss them into salads for a tiny, crunchy surprise, add them to salsas, or quick-pickle them.
7. Oca: The Tangy Potato Alternative
Let's end our tour with Oca (Oxalis tuberosa). These vibrant, wrinkled tubers are a staple crop in the Andes, second only to the potato.
What Does Oca Taste Like?
Freshly harvested Oca has a firm, crisp texture and a pronounced lemony, tangy flavor. However, if you leave the tubers out in the sun for a few days, the flavor mellows and sweetens considerably.
How to Grow Oca
Oca is a perennial that forms its tubers late in the season, triggered by shortening day length.
- Soil: Loose, fertile, well-draining soil is essential for good tuber formation.
- Sun: Full sun.
- Care: Plant certified seed tubers in the spring. Protect the plants from the first few hard frosts to give the tubers time to bulk up before you dig them up.
How to Prepare Oca
When tangy, they are fantastic sliced thinly and added raw to salads. When "cured" and sweet, they are a revelation when roasted with olive oil and herbs.
