Pugster Blue® Butterfly Bush

True-blue flowers all summer on a tidy 2-to-3-foot shrub that butterflies cannot resist. Pugster Blue® (Buddleia davidii 'Pugster Blue') delivers the big, full flower clusters of an old-fashioned butterfly bush on a compact, well-branched frame that stays in scale with modern gardens. From early summer into fall it produces dense spikes of genuinely blue blooms with a small orange-yellow eye and a light honey fragrance, drawing a steady parade of butterflies, bees, and hummingbirds. Its thick, sturdy stems give it better cold-hardiness than most dwarf types, and the gray-green foliage stays neat all season. At just 2 to 3 feet tall and wide, it suits the front of a border, a sunny foundation bed, or a large container without the leggy sprawl of older varieties. Why growers choose the Pugster Blue® Real blue color. Few shrubs offer a true blue; these full-size flower clusters read distinctly blue with a bright contrasting eye, not the washed-out lavender common in the genus. Months of bloom. Flowering runs from summer well into fall on new growth, so the show keeps coming through the warmest part of the year. Pollinator magnet. The nectar-rich, lightly fragrant spikes pull in butterflies, bees, and hummingbirds from morning to dusk. Compact and well-built. A naturally dwarf 2-to-3-foot habit with thick stems means a fuller, more cold-tolerant plant that holds its shape without staking. Tough and deer resistant. Hardy in zones 5-9, fast to establish, drought tolerant once settled, and reliably passed over by browsing deer. Use Pugster Blue® as a low-maintenance anchor at the front of a mixed border, mass several for a low flowering hedge, tuck one into a sunny foundation planting, or feature it in a large patio container at the heart of a pollinator garden.
