Our Top 5 Odd Vegetables to Grow (And How to Do It!)

Ready to get your hands dirty? This isn’t just a list; it’s your complete starter odd vegetables to grow guide. We’ve selected five incredible vegetables that are as rewarding to grow as they are to eat. Don’t worry—most of these are surprisingly easy, even for beginners!

1. Cucamelon (a.k.a. Mouse Melon)

These are, without a doubt, one of the most charming vegetables you can grow. They look like doll-sized watermelons but deliver a bright, crunchy flavor that’s like a cucumber soaked in lime juice. They are incredibly prolific and fun to snack on right off the vine.

How to Grow:

  1. Planting: Start seeds indoors about 4 weeks before your last frost date. Transplant them outside when the soil is warm and all danger of frost has passed.
  2. Sun & Soil: They love full sun and rich, well-draining soil. Amending your soil with compost will give them a great start.
  3. Support: Cucamelons are vigorous climbers! Give them a sturdy trellis or fence to scramble up. This keeps the fruit clean and makes harvesting a breeze.
  4. Watering: Keep the soil consistently moist, especially during hot, dry spells.

2. Romanesco Broccoli (Fractal Broccoli)

Romanesco is nature’s mathematician. Each head is a stunning example of a fractal, with smaller buds repeating in a perfect spiral. It has a milder, nuttier flavor than broccoli and a wonderful, firm texture. It’s a showstopper in the garden and on the plate.

How to Grow:

  1. Planting: Romanesco is a cool-weather crop. For a fall harvest (which is often best), start seeds indoors in mid-summer and transplant out when temperatures begin to cool.
  2. Sun & Soil: It needs at least 6 hours of full sun and fertile, well-drained soil.
  3. Watering: Consistent water is key. Uneven watering can lead to small, disappointing heads.
  4. Pest Watch: Keep an eye out for cabbage worms! Floating row covers can be a gardener’s best friend to protect them when they’re young.

3. Kohlrabi (German Turnip)

Looking like a little green or purple spaceship landed in your garden, Kohlrabi is a member of the cabbage family. The part you eat is the swollen stem, which has a crisp, juicy texture and a sweet, mild flavor reminiscent of a broccoli stem or jicama.

How to Grow:

  1. Planting: Sow seeds directly in the garden in early spring for a summer harvest, or in late summer for a fall harvest. They grow fast!
  2. Sun & Soil: Full sun and fertile soil are ideal. They aren’t too fussy but appreciate compost.
  3. Spacing: Give them room to “bulb up.” Space plants about 6-8 inches apart.
  4. Harvesting: Harvest them when the bulbs are about the size of a tennis ball (2-3 inches in diameter). If they get too big, they can become woody.

4. Glass Gem Corn

This isn’t your typical sweet corn. Glass Gem corn is an heirloom flint corn renowned for its breathtaking kernels that shimmer like colorful jewels. While not ideal for eating off the cob, it makes incredible popcorn or can be ground into a beautiful cornmeal.

How to Grow:

  1. Planting: Plant directly in the garden well after the last frost, as corn needs warm soil. Plant in a block of at least 4×4 rows, not a single long row, to ensure good wind pollination.
  2. Sun & Soil: Corn is a heavy feeder and needs full, blazing sun. Work plenty of compost or aged manure into the soil before planting.
  3. Watering: It’s a thirsty plant, especially when the tassels appear. Deep, consistent watering is crucial.
  4. Harvesting: Leave the ears on the stalk until the husks are completely dry and brown. That’s when the colors are at their peak.

5. Oca (New Zealand Yam)

For the slightly more adventurous gardener, Oca is a fascinating tuber from the Andes. It produces brightly colored, tangy tubers in shades of pink, yellow, and red. When cooked, the tangy flavor mellows into something akin to a roasted potato with a hint of lemon.

How to Grow:

  1. Planting: Plant tubers in the spring after your last frost. Oca is a bit different because it forms its tubers late in the season.
  2. Sun & Soil: Full sun and loose, well-draining soil are best.
  3. Day-Length Sensitive: Here’s the tricky part. Oca only starts forming tubers when the days get shorter in the fall. This means it needs a long growing season.
  4. Harvesting: Wait until the foliage has been killed back by a hard frost. Carefully dig up the tubers, cure them in the sun for a few days to sweeten, and then store them in a cool, dark place.

Your Odd Vegetables to Grow Care Guide: Best Practices for Success

While each plant has its quirks, following some universal odd vegetables to grow best practices will set you up for a bountiful and bizarre harvest. Think of this as your foundational odd vegetables to grow care guide.

Soil, Sun, and Water Essentials

Most vegetables, odd or not, thrive with the big three: full sun (meaning 6-8 hours of direct sunlight per day), rich soil, and consistent water. Before planting, always amend your garden beds with a generous amount of compost or well-rotted manure. This improves soil structure, drainage, and nutrient content all at once.

Starting from Seed vs. Starts

You probably won’t find Romanesco seedlings at your local big-box garden center. For most of these unique varieties, you’ll need to buy seeds online from specialty or heirloom seed companies. Starting seeds indoors can give you a valuable head start on the growing season, which is especially important for long-season crops.

Trellising and Support

Don’t underestimate the power of vertical growth! Vining plants like cucamelons produce more fruit and are healthier when grown on a trellis. It improves air circulation (reducing disease risk) and makes finding and picking your harvest so much easier.

Troubleshooting: Common Problems with Odd Vegetables to Grow

Even the most experienced gardeners run into issues. Knowing how to spot and solve the common problems with odd vegetables to grow will keep you from getting discouraged. Here’s what to watch for.

Pest Patrol: Who’s Nibbling on My Novelties?

While some odd veggies are less targeted, they aren’t immune. Aphids can be a problem on tender new growth. A strong spray of water can often knock them off, or you can use an insecticidal soap. For Romanesco and Kohlrabi, be vigilant for cabbage worms (the little green caterpillars). Hand-picking is effective, and floating row covers are a fantastic preventative measure.

Disease Dilemmas

The best defense is a good offense. Powdery mildew can affect vining crops like cucamelons, especially in humid weather. You can prevent it by ensuring good air circulation (trellising helps!) and by watering the base of the plant, not the leaves. Crop rotation is another key practice for long-term soil health and disease prevention.

“Why Isn’t It Growing?” – Germination & Growth Issues

Patience, my friend! Some heirloom seeds can be slower to germinate than modern hybrids. Make sure your soil is warm enough for seeds like corn. If plants seem stunted, it could be a nutrient issue. A mid-season feed with a balanced organic fertilizer can often give them the boost they need.

Frequently Asked Questions About Odd Vegetables to Grow

Are these unusual vegetables hard for beginners to grow?

Not at all! I specifically chose vegetables like cucamelons and kohlrabi for this list because they are incredibly easy and rewarding. While something like Oca is a bit more advanced due to its day-length sensitivity, many odd vegetables are just as simple to grow as a standard cucumber or radish.

Where can I even buy seeds for these plants?

Your best bet is online. Look for reputable heirloom and rare seed companies. A few popular choices include Baker Creek Heirloom Seeds, Seed Savers Exchange, and Johnny’s Selected Seeds. They offer a treasure trove of unique varieties you’ll never find locally.

How do I cook with something like Kohlrabi or Oca?

Think simple! Kohlrabi is fantastic raw—just peel it and slice it into sticks for a crunchy snack or shred it into a slaw. It’s also delicious roasted with a little olive oil and salt. Oca can be roasted just like small potatoes until tender and slightly caramelized.

Can I grow these odd vegetables in containers?

Absolutely! Cucamelons are fantastic in large pots with a trellis. Kohlrabi also does very well in containers. For larger plants like Glass Gem Corn or Romanesco, you’ll need a very large container (think half-whiskey-barrel size) and be extra diligent about watering and feeding.

Ready to Embrace the Weird and Wonderful?

We’ve journeyed through the looking glass of the vegetable world, from fractal broccoli to jewel-toned corn. The biggest takeaway? Don’t be afraid to experiment. The core of these odd vegetables to grow tips is to have fun and be curious.

Growing something new is an adventure. It connects you to the food you eat, adds incredible life to your garden’s ecosystem, and provides flavors you simply can’t buy. You’ll have successes and maybe a few learning moments, but that’s what gardening is all about.

So pick one that sparked your interest, find a seed packet, and make a little space in your garden for something wonderfully weird this year. You might just discover your new favorite vegetable.
