Butterfly Bush, 'Blue Chip' - - Buddleia hybrid
A miniature butterfly bush with all the appeal of traditional varieties in a non-invasive, smaller package. Spikes of showy, purple-blue, sweetly fragrant, small flowers rebloom continuously from mid-summer through fall. The leaves are dark green. This compact shrub stays 24"-30" tall and wide without pruning. "Blue Chip" is fast growing, heat and frost tolerant, somewhat drought tolerant and deer resistant. It can be used to attract butterflies and hummingbirds and for accent, container, layered, border, and foundation plantings. Plant in full sun, well-drained soil. (zones 5-9)
Foliage in northern zones will die back in winter. In late winter or early spring, stems can be cut back to the base. "Blue Chip" blooms on new wood, growing up from the roots. While pruning is optional, it may increase flowering. Deadheading is not necessary. This is a sterile male cultivar which forms a compact mound. Native to China.
