Big flowers on a small plant! Pugster Periwinkle® is a whole new look for butterfly bush - it offers a small, sturdy frame with flowers the size you'd find on much larger plants. Each bloom is a full, dense cluster of soft purple blooms, emitting a honey-sweet fragrance. Like all Proven Winners butterfly bushes, it blooms all summer without deadheading. Because of their thick, strong stems, Pugster butterfly bushes have better hardiness and winter survival in zone 5 than other dwarf varieties. (CPBRAF)
