Buddleja davidii Buzz Sky Blue (Butterfly Bush) is a compact deciduous shrub with gracefully arching branches, studded with lance-shaped, gray-green leaves and sweetly scented, elongated panicles of sky blue flowers. Borne at the tips of the current year’s growth, the flower spikes are freely produced from mid-summer through early fall and sometimes to the first frost. A superb, easily-grown, dwarf Butterfly Bush that is favored by butterflies and provides late summer to fall flowers when few other shrubs are in bloom. Excellent for cutting and perfect for small gardens and containers.

Buzz buddlejas are the result of a long, intensive breeding program. The goal was to produce a form of buddleja that was compact, free-flowering with good flower color, and sterile.
