Full sized flowers on a dwarf plant!
Meet Pugster® Amethyst butterfly bush - the newest member of this unique series that offers full sized flowers on a dwarf plant. This compact butterfly bush reaches just 2'/.6 m tall and wide but has the large, full flowers normally seen on a much larger plant. It blooms non-stop from early summer through frost with amethyst-toned flowers, each with a tiny yellow-orange eye in the center. Thanks to thick, sturdy stems, the Pugster® series offers vastly improved hardiness and winter survival over other types of dwarf butterfly bush.
Top reasons to grow Pugster Amethyst butterfly bush:
- Appealing light purple colored flowers, a light and cheery element in the landscape.
- It produces full-sized flowers on a compact, dwarf frame.
- Thick, sturdy stems ensure better winter hardiness in zone 5 than other dwarf butterfly bush.
