Chrysalis Steel Blue Butterfly Bush (Buddleia hybrid ‘Balchryeel’) stands out with its soft, silvery-blue flower clusters and compact, mounded form. Its showy blooms appear from late spring into summer, drawing butterflies, bees, and hummingbirds to the garden. Growing just 20 to 28 inches tall and 18 to 24 inches wide, this dwarf shrub fits effortlessly into limited spaces while still making a stunning impact. Hardy down to -25°F, it handles cold climates and continues to bloom prolifically once established, making it a standout choice among butterfly bushes.
Its elegant cone-shaped flower clusters feature a subtle fragrance that enhances a pollinator-friendly garden. Deer and drought resistance make it well-suited for a range of conditions, including warmer zones where its stems often remain above ground year-round. This low-maintenance variety adapts to different soil types and thrives in containers, borders, or mass plantings. It was bred for excellent hardiness and the ability to resist common diseases, so you can enjoy months of colorful, pollinator-attracting flowers.
Chrysalis Steel Blue Butterfly Bush Care
Plant your butterfly bush in a location with full sun for at least six hours per day, in soil that drains well. Water regularly during the first growing season, then reduce to moderate watering once roots are established. A balanced, slow-release fertilizer each month through the active growing season helps maintain continuous flowering. While not fussy about pH, slightly alkaline to neutral soils typically work best. In colder climates, the plant may go dormant and resprout in spring, while in milder regions it can remain semi-evergreen with green stems above ground.
If growing in containers, check soil moisture more frequently to avoid over- or under-watering. Container-grown plants may require occasional rejuvenation pruning to encourage fresh shoots and ongoing flowering. In harsh winter areas, moving potted specimens to a sheltered spot can protect the roots.
Prune lightly after the major flush of flowers if desired, focusing on removing spent blooms or stray branches. Cutting back in late winter or early spring to around 12 inches above the ground is often effective, especially for those in colder zones. Cut back any damaged wood or unruly stems in early spring before new growth emerges. In regions where it remains above ground year-round, trim after the last blossoms fade.
Chrysalis Steel Blue Butterfly Bush Spacing
For row or mass plantings, place shrubs 20 to 24 inches apart to create a continuous line of greenery. If you’re using it as a single specimen or accent, provide around 3 feet of space on each side to showcase its mounded habit. This spacing helps maintain healthy air circulation and a balanced garden display. For container use, select a pot approximately 12 to 14 inches in diameter so the root system has room to expand.

?
"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
