A small plant with big impact!

Pugster Amethyst butterfly bush is a versatile, space-saving dwarf variety with big, beautiful blooms of clear amethyst purple. Each one is dotted with a cute yellow eye in the center and emits the sweetest honey scent. You'll love it, but not as much as the butterflies it attracts, and they flock to it by the score.

So cute

The Pugster is so small and cute but still has big vivid blooms. I'm planting it in a special place in the garden where it can be seen, and its fragrance enjoyed and am looking forward to years of having this sweet miniature plant.
