13 Vegetables That Basically Grow Themselves (And Why Your Ancestors Never Stopped Planting Them)

Somewhere along the way, we got talked into believing that growing your own food had to be hard. Daily watering, constant weeding, replanting every single season — no wonder most people give up and reach for store-bought. But here’s what nobody told you: some vegetables were designed by nature to take care of themselves. These are the low maintenance vegetables that have fed families for centuries, and most modern gardeners have never even heard of them.

Some of these you may already be pulling out of your garden and throwing away. Others you’ve simply never thought to plant. All of them share one thing in common — once they’re in the ground, they get to work and largely don’t stop.

Here are 13 vegetables that grow with almost no help from you.


1. Jerusalem Artichoke The Set-It-and-Forget-It Tuber

Despite the name, Jerusalem artichokes have nothing to do with Jerusalem — they’re actually a Native American sunflower that indigenous peoples cultivated long before European settlers arrived. Plant the tubers once in fall or early spring and you’ll never need to replant. Each plant can yield two to five pounds of nutty-flavored tubers per season, and any small pieces left in the soil will sprout into new plants the following year. They grow eight to ten feet tall, tolerate clay or sandy soil, handle shade and drought, and attract pollinators with bright yellow blooms. During World War II, the British government actively promoted this plant specifically because it produced substantial food with almost no effort. If spreading is a concern, grow them in a dedicated bed — but for most low-effort gardeners, the fact that they multiply on their own is the whole point.

2. Lamb’s Quarters The Weed You Should Stop Pulling

Archaeologists found lamb’s quarters seeds in the stomach of a 2,000-year-old bog body — evidence that humans have been eating this plant for at least 8,000 years, predating wheat and corn. USDA nutritional data shows it outperforms spinach in protein, calcium, iron, and vitamin A. The seeds can be cooked like quinoa. And the plant asks almost nothing in return — it self-seeds every fall, comes back every spring, and thrives in poor soil conditions that would kill most garden vegetables. Harvesting the young tender leaves encourages it to keep producing. Chances are it’s already growing in your garden. You’ve just been removing it.

3. Egyptian Walking Onion The Onion That Plants Itself

This ancient allium doesn’t produce flowers — instead, it grows clusters of small bulbs at the top of its stalks. As those bulbs mature and get heavy, the stalk bends to the ground and the bulbs take root, effectively walking the plant to a new location over time. Plant Egyptian walking onions once and you’ll have a continuous harvest for years. The green tops taste like scallions year-round, the underground bulbs work like shallots, and the aerial bulbs can be pickled or shared with neighbors. Hardy down to USDA zone 3, this plant genuinely asks nothing of you beyond the initial planting.

4. Sorrel The Perennial Green That Beats Every Spring Vegetable to the Table

Sorrel has been a fixture in French kitchen gardens since medieval times, and for good reason — plant it once and harvest from the same plant for ten to fifteen years. It emerges in early spring weeks before lettuce or spinach, delivering fresh greens right when you want them most. Its tart, lemon-flavored leaves are rich in vitamin C and hold up well in salads, soups, and sauces. Sorrel tolerates partial shade, making it useful in spots under trees where other vegetables struggle. Simply remove the flower stalks as they appear to keep the plant focused on leaf production rather than going to seed.

5. Good King Henry The Medieval Green That Never Bolts

This one nearly disappeared from cultivation entirely, and that’s a shame. Good King Henry sustained European villages through harsh winters for over 400 years before modern agriculture moved on to faster-growing annuals. It functions like a perennial spinach that simply doesn’t bolt in summer heat — a problem that frustrates nearly every gardener who tries to grow traditional spinach through June and July. The young spring shoots can be harvested and cooked like asparagus. A single plant produces for twenty years or more and thrives in heavy clay soil that defeats most vegetables. Seed companies stopped carrying it largely because it only needs to be purchased once. That alone tells you something.

6. Miner’s Lettuce The Shade Garden Solution

During the California Gold Rush of 1849, many prospectors died not from injury or conflict but from scurvy — vitamin C deficiency from poor diets. The survivors learned from Native Americans about a small plant with round, distinctive leaves that grew abundantly in shaded areas. Miner’s lettuce earned its name by keeping people alive. For modern gardeners, its value is simpler: it grows in shaded spots where almost nothing else will, self-seeds prolifically once established, and provides mild, tender salad greens throughout winter in temperate climates. Scatter seeds in fall and largely forget about them. By spring you’ll have more greens than you know what to do with.

7. Watercress The Ancient Healer You Can Grow in a Container

Hippocrates reportedly built his first hospital near natural watercress springs around 400 BC, believing in the plant’s restorative properties. Roman soldiers spread it across Europe to keep their legions healthy. Modern research has caught up — watercress contains more vitamin C per calorie than oranges and more calcium per serving than milk. For gardeners, the practical magic is this: you can root cuttings from a grocery store bunch in a glass of water, transplant them into a container sitting in a tray of water, and have watercress producing indefinitely with almost no maintenance. It spreads on its own once established and keeps going for years.

8. Sea Kale The Forgotten Victorian Delicacy

Thomas Jefferson grew sea kale at Monticello after encountering it in France. Victorian English gardeners considered it among the finest vegetables available. Then refrigerated transport made cheap produce from warmer climates accessible year-round, and sea kale nearly vanished. It’s worth reviving. Sea kale evolved on rugged European coastlines, meaning it was built for poor sandy soil, drought, and neglect. A single planting produces for ten years or more. The forced spring shoots have a delicate, nutty flavor that gourmet restaurants now charge premium prices for. Its ornamental blue-green foliage is attractive enough to plant in a front yard bed. If your garden has dry, challenging soil that defeats everything else, sea kale is worth trying.

9. Horseradish The Plant That Defeated Medieval Monks

Medieval monks grew horseradish for cooking and medicine — then spent centuries trying to keep it contained. Stone walls didn’t stop it. Any root fragment left in the soil sprouted new plants regardless of their efforts. Their documented frustration is your gain as a low-effort gardener. Plant one root cutting and you’ll have horseradish indefinitely. It tolerates poor soil, drought, shade, and complete neglect. The roots actually develop better flavor after the first hard frost. Young leaves are edible as cooking greens. Researchers at the University of Illinois Extension have studied its compounds for antimicrobial properties. Just be thoughtful about where you plant it — it will stay there.

10. Scarlet Runner Beans The Flowering Vine That Feeds You for Years

Aztec farmers in the highlands of Central America relied on scarlet runner beans as a staple food for generations. The Spanish brought them to Europe in the 1600s, where they were initially grown mainly for their striking red flowers. Here’s what most gardeners don’t know: in USDA zone 7 and warmer, the roots survive winter and resprout each spring. Plant once, harvest beans for years. The brilliant red blossoms attract hummingbirds and as a legume, scarlet runner beans fix nitrogen from the air and improve your soil with each passing season. In zone 6, heavy mulching over the roots through winter often gets them through. Few plants offer this combination of beauty, food production, and soil improvement with so little ongoing effort.

11. Perpetual Spinach The Solution to Every Spinach Grower’s Frustration

If you’ve ever watched a carefully tended bed of spinach bolt into bitter uselessness the moment temperatures climb, perpetual spinach is your answer. It belongs to the chard family rather than true spinach, which means it simply doesn’t bolt in summer heat. One planting can yield harvests for three to five years. It overwinters in milder climates, providing greens when little else is producing. Harvest the outer leaves continuously and the plant keeps pushing new growth from its center. In its second year it may self-seed, generating new plants on its own. For anyone in zones 5 through 9 who has given up on summer greens, this one is worth trying immediately.

12. Purslane The Omega-3 Powerhouse You’re Probably Already Pulling

Mahatma Gandhi cited purslane as an important part of his diet. NASA evaluated it as a candidate crop for sustaining astronauts on long-duration space missions. Most American gardeners pull it out and throw it away. Purslane contains more omega-3 fatty acids than any other leafy vegetable ever studied — seven times more beta-carotene than carrots, plus meaningful amounts of vitamins A, C, and E. According to the University of Minnesota Extension, it thrives in hot dry conditions that kill lettuce and spinach, self-seeds prolifically, and returns each year with more vigor. You don’t need to plant purslane. You need to stop removing it. Check your garden beds — it’s almost certainly already there.

13. Tree Collards The Twenty-Year Harvest

Most vegetables are planted annually. A few come back for several years. Tree collards can produce harvests for twenty years or more from a single planting. African varieties and perennial European kales develop woody trunks over time, essentially becoming small trees that keep putting out leaves season after season. The purple tree collard variety carries particular historical significance — plants growing today descend from cuttings brought to America by enslaved Africans who carried pieces of their homeland with them. They tolerate light frost and summer heat, grow in poor soil, and need minimal water once established. A cutting planted today could still be feeding your family two decades from now.

One Actionable Takeaway

You don’t need to overhaul your entire garden at once. Start with one or two of the easiest entries — Jerusalem artichoke or lamb’s quarters if you want something nearly foolproof, sorrel or perpetual spinach if you want reliable greens. Let purslane or lamb’s quarters grow if they’re already showing up in your beds. Within one season you’ll understand why gardeners who work with these plants instead of against them get more food with dramatically less effort. The seed industry has largely moved away from perennials and self-seeders because they’re a one-time purchase. Your great-grandparents grew them because they worked. That hasn’t changed.
