Perennial vegetables are plants that are both perennial and vegetables. Their use surpasses just planting them in the garden as an edible alternative to an annual vegetables such as tomatoes and peppers. What I propose is to consider using perennial vegetables as analogs to conventional ornamental plants, and, as such I have created categories that mimic their use in the landscape. Perennial vegetables can be used as accent plants, border plants, ground covers, hedges, shrubs, trees and vines creating a nutritional oasis. A perennial vegetable landscape is both aesthetically pleasing, and makes good use of resources: if you’re going to water it, you might as well be able to eat it.
