Grand Cascade Butterfly Bush

Grand Cascade Butterfly Bush (Buddleia 'Grand Cascade')

Grand Cascade Butterfly Bush (Buddleia 'Grand Cascade') is a commanding presence in the summer landscape, known for producing some of the largest flower panicles of any butterfly bush. With cascading lavender blooms that reach over a foot long, this vigorous cultivar offers unmatched visual drama and an irresistible draw for butterflies and hummingbirds. Its grand size and striking display make it an ideal choice for open spaces where bold form is welcome.

Distinctive Features

Growing 5 to 6 feet tall and equally wide, Grand Cascade forms a broad, rounded shrub with arching stems that hold massive, fragrant flower spikes from midsummer into fall. Each inflorescence can grow 12 to 14 inches long and drapes gracefully downward, giving the plant a weeping appearance in full bloom. Unlike upright varieties, the cascading habit adds a softer, more relaxed feel while maintaining impressive stature and floral volume. The lavender-purple color and sheer size of its blooms make it one of the most show-stopping Buddleia available.
