Buddleja davidii 'Black Knight' – Butterfly Bush (1L / 2L)

Buddleja davidii 'Black Knight' is a deciduous shrub renowned for its dramatic, velvety-black-purple flower plumes that fill borders and containers with fragrance from late summer into autumn. The blossoms attract butterflies, turning your garden into a lively pollinator paradise. This compact cultivar is ideal for borders, patios, or container planting in 1L or 2L pots.

Culture notes: plant in full sun in well-drained soil. Prune hard in March to encourage fresh growth; as with many Buddleja, flowering occurs on new wood, so renewal pruning helps guarantee a spectacular display each year.
