Monarch® Butterfly Bush 'Blue Knight' - Blue Flowering Shrub

Introducing the exquisite 'Blue Knight' Butterfly Bush, the latest addition to the esteemed Monarch® Butterfly Bush Collection by Walters Gardens. This captivating plant is designed to elevate your garden with its stunningly vibrant blooms and wildlife-friendly properties.

Growing to a height of 4 to 5 feet and spreading up to 6 1/2 feet wide, the Blue Knight butterfly bush stands out with its impressive flower panicles. Starting in late summer, these panicles unfurl in shades of lavender and mature into a rich blue-purple hue, reaching an impressive 10 to 12 inches in length. As other flowering shrubs begin to wind down, Blue Knight comes to life, offering an enviable burst of color that extends into early fall.

Its dark blue-purple flowers contrast beautifully with soft green foliage, creating a picturesque backdrop for vibrant companion plants such as Mellow Yellows Echinacea, lavender plants, Veronicas, coreopsis, and ornamental grasses. This late-blooming butterfly bush doesn’t just add beauty—it actively supports your garden's ecosystem. Birds, bees, and hummingbirds are irresistibly drawn to its honey-scented blooms.

Plant the Blue Knight in full sun, ideally near sitting areas, to fully enjoy its delightful fragrance and the soft buzz of visiting pollinators. Transform your garden with the unforgettable allure of the 'Blue Knight' Butterfly Bush.
