12 Perennial Vegetables You Can Plant Once and Harvest Forever

Perennial vegetables are a fantastic addition to any garden because they come back year after year without needing to be replanted. Here's a list of 12 perennial vegetables that you can plant once and harvest continuously:

  1. Asparagus: Asparagus plants can produce for 15-20 years once established. They take a couple of years to mature but yield a bountiful harvest of delicious spears each spring.

  2. Artichokes: Globe artichokes are perennial plants that produce edible flower buds. They thrive in warmer climates and can yield for several years once established.

  3. Rhubarb: Rhubarb is a hardy perennial that produces edible stalks. It's low-maintenance and can provide harvests for many years.

  4. Jerusalem Artichokes (Sunchokes): These are actually a type of sunflower, and their tubers are edible. Once planted, they can become somewhat invasive but provide a good harvest of tubers.

  5. Horseradish: Horseradish is a perennial root vegetable that is easy to grow and provides spicy, flavorful roots.

  6. Sorrel: Sorrel is a perennial herb with tangy leaves. It's easy to grow and harvest, and the leaves can be used in salads or cooked dishes.

  7. Walking Onions (Egyptian Onions): These onions produce bulbs at the top of the stalks. When the bulbs get heavy, they bend to the ground and replant themselves, hence the name "walking onions."

  8. Good King Henry: This lesser-known perennial green has spinach-like leaves and is quite hardy once established.

  9. Lovage: Lovage is a perennial herb that resembles celery in taste. It's used for its leaves and stems and is relatively low-maintenance.

  10. Sea Kale: Sea kale is a perennial vegetable that produces edible shoots similar to asparagus. It's tolerant of salty conditions and thrives in coastal areas.

  11. Perennial Kale: There are certain varieties of kale that are perennial. Once established, they can provide a continuous harvest of nutritious leaves.

  12. Chinese Artichoke (Crosne): Crosne is a perennial tuber that resembles a small, knobby ginger root. It's a unique addition to the garden and produces small, crisp tubers.

These perennial vegetables vary in their growing conditions and maintenance requirements, but once established, they can provide a continuous harvest year after year, making them a great choice for a low-maintenance garden.
