Butterfly Bush (Buddleia davidii) – Originating from China, Butterfly Bush is a delicious, perennial shrub known for it’s long plumes. The plumes feature a cascade of tiny, nectar rich flowers that attracts and provides food only, to adult butterflies, bees, hummingbirds and and other beneficial insects. The flowers colors can range from shades of blues, violet and purple but are generally white, pink and red.
Buddlelia is fast growing, deer resistant and low maintenance. It can grow to reach heights of 6 to 8 feet. Buddlelia requires full sun to reach its optimum flowering potential. It also requires well draining, average to slightly acidic soil. It does not, however, like excessive wet soil. Once the plants are established, they become drought tolerant and require only occasional watering unless subjected to extreme heat. Aggressive pruning during late fall only is recommended in mild climates. In cold climates, Buddlelia should be cut close to the ground (be forewarned the stalks are woody and tough) and mulched heavily until spring. Buddlelia generally flowers the first year, when started early (blooms from summer to autumn).
The bad news: Buddlelia is becoming a invasive species in many climates; in particular the Pacific Northwest (has been banned in Oregon) and most of the eastern seaboard. Because seeds are easily dispersed naturally by weather and birds, deadheading spent plumes is recommended. The good news is non-invasive varieties have been cultivated and are perfect for perennial gardens and containers.
