Buddleja or Buddleia is a genus containing over 140 deciduous, evergreen and semi-evergreen shrubs and some trees from the Buddlejaceae family. Some plants are endemic to Africa, Asia and the Americas. Buddleia are widely cultivated for their attractive and scented flowers, coloured in shades of purple, pink and cream and are known as butterfly bushes. Most grow no taller than 5m, but many are considered invasive in certain locations, plant with care! Butterfly Bushes can flower anytime during spring, summer or autumn. There are a huge range of cultivars that have been developed for garden use, there's a colour and scent for every garden. Species such as Buddleja davidii, Buddleja alternifolia, and Buddleja crispa are particularly attractive to butterflies and other pollinating insects. These plants can be hard to control, but they are very rewarding, often filling the air with lovely smells and buzzing wildlife.
