Pugster® Blue Butterfly Bush (Buddleia x 'SMNBDBT') brings full-sized blooms to a compact, cold-hardy form, redefining what’s possible in a dwarf butterfly bush. At just 2 feet tall and 2–3 feet wide, it’s easy to merchandise in containers or tight retail spaces while still delivering the bold garden presence of larger varieties.¶It flowers continuously from early summer to frost, producing dense clusters of true-blue blooms with bright yellow-orange eyes, an eye-catching color rare in most landscapes. The thick stems provide improved winter survival in colder climates (Zone 5), making it more reliable than other dwarf buddleias. Fragrant, pollinator-friendly, and drought-tolerant, this variety checks all the boxes for retailers and landscape professionals seeking compact performance with season-long impact.
