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.
