The latest craze in landscaping, which is really not so crazy, is mixing edible plants into your landscape.
Artichokes and asparagus, for example, grow for years. To avoid tying up space in your vegetable garden, plant these in other locations around your yard. Asparagus makes an interesting, ferny plant, and artichokes grow up to several feet tall with an arching, ferny plant.
Also consider trees and shrubs that produce edible fruits or nuts that make great landscape plants. Depending on where you live, consider growing wild grape vines, nut trees like walnuts or pecans, and fruit trees. Check your local extension service office for the best varieties for your area.
Researching plants native to your area may have you discovering plants early settlers relied on long before cultivation of edibles. Not only will these plants provide you with some new tasty treats, but they will also require less maintenance on your part as they will be well adapted to your soil and climate.
