These include leaf vegetables (e.g. lettuce), stem vegetables (asparagus), root vegetables (carrot) and flower vegetables (broccoli), and botanical fruits such as green beans, cucumbers, squashes, pumpkins, tomatoes, avocadoes, capsicums, et cetera, as well as fleshy, immature seeds such as those of maize, peas or beans.
