Is there a good book you can recommend that tells the facts about them (nutrition & Storage included)
We have a wonderful book on this https://www.fruitsandveggiesmorematters.org website titled Vegetables from Amaranth to Zucchini. Look here to see the book on the on-line catalog. It is loaded with history, etymology, selection, and storage information about vegetables. I think this is a very valuable book to have.
