These butterfly bush plants have all been grown from seedlings produced here on the nursery at John Cullen Gardens. In our front garden we have many buddleja. As the seedlings will have been cross pollinated there is no sure way to know which variety they are. All of the varieties that we have planted are all under 2m in height so in theory these should not grow any taller. Loved by bees and butterflies. Full sun or part shade.
