Perennial vegetables that are not spinach substitutes?

[TheVeggieProfessor]

Much of the perennial vegetables for leafies. What about options that are more robust? Like something that can be used in cooking where a vegetable like broccoli would be used?

[Galatians522]

Asparagus, Winged bean, Chayote, Similax (new shoot tips eaten like asparagus), saccharum edule, palm hearts from many species.

I've been told Turkish rocket resembles a perennial broccoli.

And lovage resembles a perennial celery.

yacon, sweet potato,gynbura procumbens and crepioides (sorry spinach) rhubarb, mauka, perennial beans, taro, water chestnut,  arrowhead, hausa potato, pigeon pea, stachys affinis...

Tindora cucumbers, spineless cactus nopales. Akee tree fruit is used as a vegetable. Green banana and plantain are staple carbohydrate crops many places.

It just occurred to me that no one's mentioned perennial root vegetables in this thread.  (The kind where you can harvest some of the tubers / roots / corms, ignore the rest, and have them sprout back the next year.)  Are you interested in a list of those?

[UnicornEmily]

Also: the book Perennial Vegetables, by Eric Toensmeier, is a treasure trove.  I found it fascinating and very exciting, and took lots of notes.

Maybe green papaya? Some culinary traditions use the unripe fruit as a vegetable. Green papaya salad would be one famous example.

Maybe casava as well? Not exactly a vegetable but it's calorie dense and very filling. I'm pretty sure you can harvest year round.
