Perennial Vegetables to Plant for Years of Produce

1. Asparagus (Asparagus officinalis)
   Asparagus is a well-known and beloved perennial vegetable. Once planted, it can produce delicious spears for up to 20 years or more. While it takes patience to establish, the reward is worth it. Asparagus beds can be productive for decades, providing fresh spears in the spring, a delightful addition to any meal.
   Plant asparagus in well-drained soil in a sunny spot. Keep the bed weed-free and provide consistent moisture for the best results.
2. Rhubarb (Rheum rhabarbarum)
   Rhubarb is another perennial favorite in many gardens. Known for its tart stalks, it's perfect for pies, jams, and desserts. Rhubarb plants can thrive for ten years or more with minimal maintenance. They're relatively hardy and can tolerate a range of soil conditions. When planting rhubarb, choose a sunny or partially shaded location with well-drained soil. Remove the flower stalks as they emerge to encourage continued leaf production.
3. Jerusalem Artichoke (Helianthus tuberosus)
   Jerusalem artichokes, also known as sunchokes, produce knobby tubers that are deliciously roasted or used in soups and stews. These hardy perennials can be prolific once established, with tubers multiplying underground yearly. However, be cautious when planting them, as they can become invasive in some regions. Plant Jerusalem artichokes in a sunny spot in loose, well-draining soil. Harvest the tubers in late fall or early winter after the plant has died.
4. Sorrel (Rumex acetosa)
   Sorrel is an underrated perennial green with a lemony flavor. It's a versatile addition to salads, soups, and sauces. Sorrel plants are easy to grow and can be productive for many years. They also tolerate a wide range of soil types. Plant sorrel in partial shade to full sun. Regular harvesting will encourage new growth and extend the plant's life.
5. Egyptian Walking Onions (Allium proliferum)
   Egyptian walking onions are a unique perennial onion variety. They produce topsets (small onions) on top of their stalks, which eventually cause the stalks to bend over and replant themselves. This unique characteristic makes them self-propagating and capable of "walking" through your garden. Plant Egyptian walking onions in well-drained soil in a sunny to partially shaded location. Harvest the topsets and green onion stalks for a continual supply of onion flavor.
