Buddleia Buzz Lavender Buddleia is also known as the butterfly bush, because the shrub is often covered with butterflies when in flower. Buddleja davidii Buzz Lavender is a compact, long-flowering, deciduous shrub, ideal at the front of a border in a small garden, or for a patio container. The narrow elliptical leaves are an attractive grey-green, setting off the flowers beautifully. From June to September, masses of conical heads of lavender-blue flowers are carried on the shrub, providing nectar for pollinators, especially butterflies. Buddleia Buzz Lavender is easy to grow; prune in early spring to keep it in shape.
