Product Description

Buddleia Pugster Amethyst®, commonly known as Butterfly Bush, is a compact, hardy cultivar celebrated for its full-size amethyst-purple flower spikes on a dense, dwarf plant. Reaching only 2 to 3 feet tall and wide, it delivers nonstop blooms from midsummer to frost, all while supporting pollinators like butterflies, bees, and hummingbirds. Unlike many dwarf varieties, Pugster Amethyst® features thick stems for improved winter survival in colder zones. Its tidy shape, fragrant flowers, and strong performance make it ideal for borders, containers, and sunny pollinator gardens.

Frequently Asked Questions

Is Pugster Amethyst® Butterfly Bush native to the United States?

No. Buddleia species, including the Pugster® series, are native to Asia, and Pugster Amethyst® is a modern hybrid cultivar bred for compact size and improved cold tolerance. It is a non-native ornamental and does not provide the same ecological benefits as native flowering shrubs.

What makes Pugster Amethyst® different from other butterfly bushes?

Pugster Amethyst® is part of the Pugster® dwarf series, bred for full-size flowers on a compact plant. It grows only 2 to 3 feet tall and wide, with large, fragrant lavender-purple blooms that appear from summer through frost. It also features thick, sturdy stems for better winter survival in colder climates.

What are the ideal growing conditions for Pugster Amethyst®?

This plant thrives in full sun and prefers well-drained soil. It is drought-tolerant once established, and hardy in USDA zones 5 through 9. Avoid planting in poorly drained or wet soils, especially in winter, and cut back in early spring to encourage vigorous growth and blooming.

Is Pugster Amethyst® good for pollinators?

Yes, to a degree. The blooms are highly attractive to butterflies, bees, and hummingbirds, offering abundant nectar. However, like all Buddleia species, it does not serve as a host plant for native caterpillars, so it supports adult pollinators only, not full life cycles.

Is Pugster Amethyst® invasive or deer-resistant?

Pugster Amethyst® is non-invasive—it is a sterile cultivar that does not self-seed, making it a safer alternative to older Buddleia varieties in areas where invasiveness is a concern. It is also deer-resistant and low-maintenance, needing only basic pruning and occasional watering in dry spells.
