Summary

Cascading pink flower wands that light up the late-summer garden.

'Pink Cascade II' brings a fresh burst of color just when many beds are winding down. Each long, puffed panicle arches outward like a waterfall, creating movement and dimension you can appreciate from across the yard. The blooms carry a sweet, honeyed fragrance that draws butterflies, bees, and even hummingbirds in droves—turning your border into a living pollinator show.

Compact yet impactful, this shrub maintains a clean, rounded habit around 4' x 4–4.5', making it easy to place near pathways, in mixed borders, or as a low specimen in the front yard. The improved flower form over the original ‘Pink Cascade’ means fuller, showier spikes and a more dramatic display with minimal fuss. It’s a true “set-and-enjoy” performer for sunny sites with good drainage.

Color-wise, the warm pink tones partner beautifully with silver foliage (artemisia, lavender), late-season blues and purples (salvia, catmint, Russian sage), and prairie textures (panicum, little bluestem). The bloom window stretches from late summer into fall, bridging the gap between midsummer perennials and autumn seedheads for continuous interest.

Gardeners love its easygoing nature and strong deer resistance. It’s also believed to be sterile (little to no seed set), which keeps maintenance low and helps avoid unwanted seedlings. If you’re designing for a pollinator-friendly landscape, a late-season focal point, or a fragrant walkway planting, Pink Cascade Butterfly Bush delivers big show with a compact footprint.

Care

Pink Cascade Butterfly Bush Care

Plant in full sun with fertile, well-drained soil. Adding lime can improve vigor and flower quality. Water regularly during the first season to establish; once established, water needs are average to low.

Blooms on new wood. Each spring, cut back old wood to about 12" to encourage a tidy shape and prolific flowering. Buddleia can break dormancy late—be patient as temperatures warm.

Feed in early spring with a slow release fertilizer for steady growth and season-long performance.
