Perennial vegetables are plants that live for multiple years, producing edible parts without needing to be replanted each season. Unlike annual vegetables, which must be sown every year, perennials establish deep root systems that allow them to thrive in various conditions. Examples include asparagus, rhubarb, and artichokes. These vegetables often require less maintenance and can contribute to sustainable gardening practices. They help improve soil health and reduce the need for fertilizers, making them an eco-friendly choice. Additionally, perennial vegetables can provide a continuous harvest, offering fresh produce year after year.
