Important Note:

* Hardiness Zone: The survival of these vegetables depends on your specific climate and hardiness zone. Check your USDA plant hardiness zone to ensure you are choosing varieties suited to your area.

* Winter Protection: In colder climates, you may need to protect your perennial vegetables from frost and extreme cold. Mulch, row covers, and cold frames can provide insulation.

It's also important to note that even within a single hardiness zone, there can be microclimates that affect plant survival.
