Growing at a glance…
Buddleia are well known for the hardiness that they provide, making them a perfect choice for long-term borders/rockeries. They can be pruned hard after flowering, and you should cut shoots back to strong buds/younger growth. Do not let plants dryout in the summer, particularly in hot weather.Buddleia can be planted in almost all types of soil, provided it is relatively fertile and that there is plenty of good drainage available. They prefer full sun or partial shade.
