Black Knight Buddleia Pint

Black Knight Butterfly Bush (Buddleia 'Black Knight') is one of the most striking shrubs you can grow for summer color and pollinator activity. Long, arching panicles of deep grape-violet flowers — the darkest of any buddleia — bloom all summer and fill the air with sweet fragrance. Hardy in Zones 5–9, it dies back in colder climates but returns vigorously each spring, often blooming even more abundantly than the year before.

Why Gardeners Choose Black Knight Butterfly Bush

• Darkest blooms of any buddleia: Deep grape-violet flowers with an intensity that sets it apart from lighter lavender varieties.
• Butterfly and pollinator magnet: One of the most effective plants for attracting butterflies, hummingbirds, and bees all summer long.
• Sweet fragrance: Blooms emit a honey-like scent that carries through the garden.
• Hardy and reliable: Returns each spring in Zones 5–9 — even if tops die back in winter, roots survive and resprout vigorously.
• Long bloom season: Flowers from midsummer through fall with regular deadheading.

Planting & Care

• Light: Full sun to part sun.
• Soil: Well-drained; slightly alkaline (pH 6.5–7.0) preferred.
• Spacing: 4–8 feet apart.
• Pruning: Deadhead regularly to encourage continuous blooming; cut back nearly to the ground in late winter for strong rejuvenation growth.
• Fertilizing: Slow-release fertilizer in spring and summer supports vigorous growth.
• Pest watch: Check for spider mites by tapping branches over white paper; treat with miticide if needed.
