Pugster® Amethyst Butterfly Bush

Pugster® Amethyst is the patented SMNBDL selection, with full-size flower clusters on a compact, mounded plant. Proven Winners lists a mature height and spread of about 2 feet, amethyst-purple flowers with yellow-orange eyes, and continuous bloom from early summer through fall. The [cultivar profile](https://www.provenwinners.com/plants/buddleia/pugster-amethyst-butterfly-bush-buddleia-x) identifies the selection as PP30,236. ## Siting Grow in full sun and well-drained soil. The breeder lists USDA zones 5–9, low water needs, and border and container uses. Thick, sturdy stems improve winter hardiness compared with other dwarf butterfly bushes, including in zone 5. ## Maintenance Flowers form on new wood, and deadheading is not needed for continued flowering. In zone 5 and colder, the breeder advises against fall planting or pruning; wait for spring growth before cutting back. Water during establishment, then adjust irrigation to local conditions and soil drainage.
