Pugster Blue Butterfly Bush
Buddleia 'Pugster Blue', Buddleia x ‘SMNBDBT’Pugster Blue Butterfly Bush is a compact yet vigorous flowering shrub prized for its oversized violet-blue flower spikes, strong fragrance, and exceptional pollinator appeal. Despite its dwarf size, this variety produces full-sized blooms that cover the plant from summer into fall, creating a vibrant display of color and movement in the landscape. The fragrant flowers are highly attractive to butterflies, honey bees, and hummingbirds, making it an outstanding choice for pollinator gardens.
This compact shrub typically reaches just 2 to 3 feet tall and wide, forming a dense, mounded habit ideal for smaller gardens, borders, containers, and foundation plantings. Unlike older butterfly bush varieties that can become large and unruly, Pugster Blue maintains a tidy shape while still delivering impressive flower power and strong garden presence.
Pugster Blue is especially valued for its thick, sturdy stems that support the large flower spikes without flopping. Its long bloom season provides continuous color through the hottest months of the year while requiring very little maintenance once established. The soft green foliage provides a clean backdrop for the richly colored blooms and adds texture to mixed plantings.
