18 Perennial Vegetables That Keep Giving Year After Year
Imagine planting once—and harvesting for years to come. That’s the magic of perennial vegetables! Unlike annuals that require replanting every season, perennials grow back year after year, saving you time, effort, and money. Whether you’re building a sustainable garden or just want fresh, homegrown food with less maintenance, this list is for you.
Here are 18 top perennial vegetables to grow in your garden that will reward you season after season.
1. Asparagus
A true garden investment. Plant crowns 8–10 inches deep in well-drained soil under full sun. Wait until the second year to harvest tender spears in spring, then enjoy fresh asparagus for up to 20 years!
Pro tip: Don’t harvest too much in the first few years to allow the roots to strengthen.
2. Rhubarb
Plant rhubarb crowns in early spring in rich, cool soil. Only harvest the stalks—the leaves are toxic. By year two, you’ll get a tart harvest perfect for pies, jams, and more.
3. Artichokes
These thistle-like veggies thrive in mild climates with fertile soil. Harvest the buds before they open for a sweet, nutty flavor. They also make a stunning addition to any garden!
4. Horseradish
Grows best in full sun with minimal care. Dig up the roots in fall for a spicy kick—perfect for sauces and marinades. Be cautious: it spreads fast!
5. Jerusalem Artichokes (Sunchokes)
Plant tubers in sandy soil and full sun. They grow tall and flower before dying back. Harvest crunchy, nutty tubers in late fall.
6. Chives
Perfect for small spaces and containers. Grow in full sun and well-drained soil. Snip leaves anytime to garnish eggs, soups, or salads.
7. Sorrel
This lemony green is one of the earliest spring risers. Plant in moist, well-drained soil. Regular picking encourages fresh growth.
8. Good King Henry
A forgotten favorite of ancient gardens. It loves rich soil and partial shade. Cut young leaves in spring and summer for a spinach-like taste.
9. Walking Onions
A fun and funky vegetable. They “walk” by forming new bulbs at the top of stalks that fall and root. Use greens like scallions or harvest the small bulbs.
10. Lovage
Tastes like celery but stronger. Plant in full sun to partial shade, and use the leaves, stalks, or even seeds in soups and stews.
11. Sea Kale
This hardy plant loves sandy, well-drained soil. Blanch young shoots in spring or eat mature leaves. Very underrated and absolutely delicious.
12. Perennial Kale
Unlike traditional kale, this one keeps growing year-round in mild climates. Pick leaves often to encourage new, tender growth.
13. Skirret
An old-world root vegetable with a sweet, nutty flavor. Plant in moist, fertile soil and dig roots in late fall or early winter.
14. Perpetual Spinach
Not a true spinach, but just as tasty. Grows in well-drained soil and offers leaves nearly all year round.
15. Tree Collards
Tall and sturdy, these leafy greens grow like a small shrub in warm climates. Harvest leaves as needed—they’re packed with nutrients.
16. Daylilies
More than just beautiful flowers! You can eat the young shoots, flower buds, and even the tubers. Just make sure your variety is edible.
17. Chinese Artichokes
These small, crunchy tubers are mild in flavor and fun to grow. Plant in loose soil and dig them up in late fall.
18. Watercress
Grow in shallow water or consistently moist soil. Packed with nutrients and ideal for salads, smoothies, or sandwich toppings.
