Vegetables That Are Native To North America

Q: Are there any vegetables that are native to North America? 

A: The only two I could find are Jerusalem artichoke and tepary bean.
Jerusalem artichoke is a type of sunflower with thick, edible roots. Patches of
tall plants covered in yellow flowers are eye-catching in autumn. Tepary bean
is a small, hearty, drought-tolerant bean that’s native to the American
southwest. The taste is described as sweet and nutty, not like a bean at all.
