Black Knight Butterfly Bush 1 Live Plant – Buddleja davidii ‘Black Knight’ – 3 Gallon Pot

Black Knight Butterfly Bush (Buddleja davidii ‘Black Knight’) is a deciduous flowering shrub known for its dramatic, deep purple-blue blossoms that can appear almost black in certain lighting. Its elongated flower clusters create a striking contrast against gray-green foliage, providing rich seasonal color in ornamental landscapes.

Flowering typically begins in early summer and may continue until the first frost under favorable growing conditions. The fragrant blooms attract butterflies and other nectar-seeking pollinators. Black Knight develops a vigorous, arching growth habit and is commonly used in sunny shrub borders, cottage gardens, and pollinator-focused landscapes where its cultivation is permitted.

Supplied as one live plant in a 3 gallon nursery pot, this butterfly bush prefers full sun and well-drained soil. It is a deciduous shrub, so foliage and overall appearance vary by season, and plants may be shipped dormant or leafless.
