Beautiful, sweet-scented blooms and a gently weeping form ensure the Lilac Cascade Butterfly Bush will be an instant favorite. Tiny purple flowers grow in 12- to 18-inch long, cone-shaped clusters that gently arch or weep, giving the Buddleia davidii a full, lush look. Blooming starts in early summer and continues until late summer.
This sun-loving shrub is a natural focal point, so include it in a bed or mass planting or create a lovely flowering border or hedge. Plant the butterfly bush in a busy area where the fragrant blooms can be enjoyed. Butterflies and other pollinators favor this fast-growing shrub, but it is deer- and rabbit-resistant for dependable foliage even in areas with a lot of foragers. The Lilac Cascade Butterfly Bush is an upright shrub that grows as a perennial in USDA zones 5 through 10.
Lilac Cascade Butterfly Bush Care
At least 6 hours of sunlight is necessary for the Lilac Cascade Butterfly Bush. This plant prefers moist, well-drained soil with high organic content. Water when the top few inches of soil dries out. While this bush is drought-tolerant, consistent watering will keep the plant healthy and blooming.
Each spring, a dose of balanced, slow-release fertilizer will support plenty of foliage and blooms. Shape this bush in late winter or early spring before new growth appears.
Lilac Cascade Butterfly Bush Spacing
Lilac Cascade Butterfly Bush is an upright perennial shrub that will grow 5 to 6 feet tall and wide. Shrubs can grow as close as 2 to 4 feet apart.
