Asparagus and rhubarb. RScott

Answer 2

Of course where you are could make a huge difference in the number of perennial vegetable, however, there are not only two. Horseradish, Rhubarb and Asparagus are perennial and in the warmer zones you can include vegetables like Cardoon, Artichoke, sorrel, chives, and parsley which are also considered a tender perennial. Not to mention that in the tropical regions, Tomatoes are a perennial. There are many not so well known leafy vegetables that are perennials as well such as can be found in this web site: http://www.agroforestry.net/pubs/perennial_vegetables.html
So, as you can see, there are more than two.
Good Luck

Answer 3

Asparagus and rhubarb are the obvious ones though tomatoes and peppers grown in tropical and subtropical regions are very long lived perennials and while both are really fruits, are considered vegetables by the USDA.

Sugarcane. Well, it's not really a vegatble, but a stem, it is perennial. And, there are some vegetables that cannot reproduce because there were genetically modified as to not be able to (ie. corn)...USDA.

Answer 7

I know Asparagus is one. You have to grow them for several years before you get any edible plants.

Rubarb is another. I've grown this too and I know it comes back each year.

I'll bet there are more, too.
