Buddleia is a familiar shrub, well-known for its attractiveness to butterflies. It is actually an introduced species, however, that has become naturalised on waste ground, railway cuttings and in towns.
How tall do Buddleia trees grow?
Many buddleja make tall shrubs, 2.5-3m (8-10ft) tall, even with hard annual pruning. If you have a smaller patch, or are looking for something for the front of the border, or a container try one of the dwarf cultivars of B davidii like the Buzz series or Nanho series. These typically reach 1-1.2m (3-4ft) tall.
