Herbs can be successfully planted into existing flowerbeds. Their subtly colored foliage and flower colors combine well with trees and shrubs.
Equally, they look stunning in decorative vegetable gardens planted in formal patterns. In flowerbeds herbs mix well with wildflowers, especially in gravel gardens where they can self-seed and enjoy well-drained Mediterrean-type growing conditions. If the reason you like an herb is purely because of its color or leaf shape, rather than its culinary or medicinal value, feel free to grow it for its appearance with other plants that you enjoy. Another reason for growing herbs with flowers in the garden is that they are popular with insects and butterflies. Plants such as Korean angelica and cardon are particularly attractive to beneficial insects.
