Buddleia, or butterfly bush, is a perfect background plant for the sun garden, and a terrific butterfly magnet. Butterfly bush is really a woody shrub. It loses its leaves, and dies back to the ground every year. In the spring, (late spring - be patient) all new growth emerges from the roots.
Buddleia develop into large arching shrubs that are covered with wands of fragrant flowers late in the season.
Grow Buddleia in well-drained, fertile soil in full sun. Once established, they are very drought tolerant. When planting, give them plenty of room. Depending on the cultivar, and Buddleia can get well over 5 feet wide. Buddleias benefit from pruning their woody stems back sometime in March or April. Plant in spring or fall, and space 5-7 feet apart. Shorter varieties, such as Blue Chip can be spaced 3-4 feet apart.
Pruning How much to prune depends on your taste. We prune about 6-8 inches from the ground, but we know gardeners that prune all the way to the ground. Pruning back hard gives Buddleias a beautiful shape and form that you will appreciate.
Slow To Start
Buddleias are very late to break dormancy. Here in Michigan, Buddleias often ‘'wake up' well into late May. Once the weather starts to warm up, you will really see Buddleias take off, and grow rapidly. We love butterfly bushes, and cannot imagine a sun garden without them. Beautiful, sweetly fragrant, and a highly desirable nectar source for butterflies!
Garden DesignView all BUDDLEIA
Buddleias should be planted in the back of the border. They add a much needed anchor and vertical element to the perennial garden. They also make an excellent hedge plant. Give them plenty of space. Blue Chip is a dwarf type that is ideal when planted in groups of 3 or more.
