Food-minded gardeners often overlook using herbs in ornamental gardens, container planters, and hanging baskets, and that's a shame, because so many of them are as attractive as they are tasty. Consider 'Pesto Perpetuo' basil as a small annual subshrub with white-edged green leaves. The more you pinch the shoots, the bushier it gets, forming an upright mound, one to two feet tall and about 18 inches wide. Planted with nasturtiums or marigolds, you'll have a a colorful, edible display that will last all summer. Sometimes, flavor is sacrificed for looks, but that's not the case with 'Pesto Perpetuo' basil. It is frost tender, so be sure to harvest all the leaves prior to the first fall frost.
