What two perennial vegetables can produce on their own for several years and do not need to be replanted every year like other vegetables?

The two perennial vegetables that can produce on their own for several years and don't need to be replanted annually are:

* Asparagus: This vegetable is known for its tough, long-lasting roots that can produce spears for 10-15 years, even longer with proper care.

* Rhubarb: This leafy vegetable's root system is also very resilient and can produce stalks for 10-15 years, sometimes even longer.

While other vegetables, like artichokes and some herbs, are technically perennials, they may require dividing or replanting after a few years to maintain optimal production.
