Additional Information

The Butterfly-Bush is valued for its profusion of attractive, fragrant purple flowers and long bloom period that can even stretch into October. The flowers of this large, tough shrub attract a considerable amount of butterflies. This plant tolerates clay soil, and drought once established, but is not tolerant of wet soils. To maintain vigor and flower size, it is recommended to give this plant a hard prune or prune to the ground in early spring, before growth begins. This plant seeds itself freely and can become quite weedy, so it is best to deadhead the old flowers, before they can go to seed. This also encourages further blooming.
