Overview

A vibrant, heavy-flowering butterfly bush ideal for Adelaide’s Mediterranean climate, Buddleja davidii ‘Blaze Pink’ produces long, arching clusters of bright pink, honey-scented blooms from late spring through autumn. Loved by bees, butterflies and beneficial insects, it brings a long season of colour and movement to borders, cottage gardens and waterwise landscapes. Tough, fast-growing and strongly tolerant of heat, wind and dry summers, it thrives in South Australia when planted in full sun and free-draining soil.
