Bicolor Butterfly Bush

Bicolor Butterfly Bush (Buddleja x weyeriana 'Bicolor')

Bicolor Butterfly Bush brings unusual summer color to the landscape with flower spikes that blend warm yellow and raspberry tones on the same panicle. Its long bloom season and strong pollinator appeal make it especially useful in sunny borders, cottage gardens, and butterfly plantings where continuous color matters. Because it flowers over a long stretch of the season and responds well to annual pruning, it can deliver a lot of impact without becoming difficult to manage. This is a strong choice for gardeners who want a distinctive flowering shrub with fragrance, movement, and a reliable focal point through summer.

Distinctive Features

This deciduous shrub forms an upright-arching to spreading habit with lance-shaped green foliage and fragrant, conical flower panicles that open in a striking mix of yellow and raspberry shades. The unusual bicolor effect sets it apart from more familiar purple, blue, or white butterfly bush selections and gives the plant a more playful, multicolored look in the landscape. Bloom begins in early summer and can continue into early fall, especially if spent flower clusters are removed. The flowers are highly attractive to butterflies and other pollinators, making the plant especially valuable in gardens designed for seasonal activity and color.

Low Maintenance Care
