The Pugster Blue® Butterfly Bush (Buddleia) is a compact, dwarf shrub known for its large, fragrant, blue-purple flowers on sturdy stems, blooming non-stop from summer to frost, attracting pollinators, and tolerating drought and deer while thriving in full sun in USDA Zones 5-9. It's ideal for containers and borders due to its small size (about 2 ft tall/wide) and requires spring pruning above new buds for best growth.
