About this plant
What makes this plant special
'Blue Chip' is a dwarf butterfly bush that forms a rounded mound about 60–75 cm tall and wide without any pruning. From midsummer until the frosts it bears fragrant blue-purple spikes above dark green foliage. It is non-invasive and copes well with drought once established.
Butterfly Bush Buddleja
Butterfly bushes (Buddleja) are fast-growing shrubs from Asia, Africa and the Americas. From late spring into autumn, depending on the species, they bear dense, often fragrant flower panicles in white, lilac, purple, pink or yellow, rich in nectar and very attractive to butterflies and other pollinators. They are among the easiest flowering shrubs to grow.
Location and soil
Butterfly bushes need full sun and any well-drained soil, including poor, stony or chalky ground. They tolerate drought and urban pollution well. Most are hardy, but the evergreen species from warmer regions need a sheltered spot or winter protection.
Pruning and care
Most species flower on the current year's shoots and are pruned hard at the end of winter, in March–April. Species that flower on older wood are trimmed just after flowering instead. Removing spent flower spikes extends flowering and limits self-seeding.
Use in the garden
Suitable as specimens, in mixed borders and informal hedges, and in large containers for the compact forms. They are a mainstay of wildlife and naturalistic gardens. The common species self-seeds readily on bare ground, so deadheading is advisable.
