Perennial vegetables tend to be low-maintenance plants and have the ability to resist pests and severe weather.
Unless you are planning on giving away your produce, choose vegetables that you love and will use when they are fully grown.
Choose perennial vegetables that you enjoy consuming. And things you can sell farm to gate are great too!
If you have a corner that is difficult to get to and you need a low-maintenance plant there, then one of your perennial vegetables may fare better than another choice.
Pick your favorites, make some plans, and you will feel very pleased that you did both now and in the future.
