Buddleja ‘White Ball’ is a compact, deciduous shrub grown for its distinctive rounded clusters of pure white flowers. Unlike the long, tapering spikes of traditional butterfly bushes, this variety produces neat, ball-shaped blooms throughout summer, creating a softer, more structured display. The gently fragrant flowers are attractive to butterflies and pollinating insects, while the tidy, bushy growth habit keeps the plant well-proportioned and manageable. Ideal for sunny borders, smaller gardens, and container planting, it delivers reliable colour and pollinator appeal without becoming oversized.
