Purple Butterfly Bush is a fast-growing flowering shrub known for its long, cone-shaped clusters of fragrant purple blooms. Flowering from summer into fall, it attracts butterflies, hummingbirds, bees, and other pollinators while adding bold color to sunny gardens. This easy-care shrub works well in mixed borders, pollinator gardens, foundation plantings, and as a colorful specimen. Regular deadheading can encourage additional blooms throughout the season.
