Spikes of intense red-violet flowers are produced in profusion throughout the summer on Miss Ruby butterfly bush (Buddleja davidii 'Miss Ruby'), a half-hardy shrub with a more compact habit than other butterfly bushes. (Its top is frequently killed to the ground in Chicago-area gardens.) This selection came from the J.C. Raulston Arboretum in North Carolina. It was the first-place winner in the Buddleja trials of the Royal Horticultural Society in 2008. Butterflies, hummingbirds, and honeybees are all attracted to the honey-scented flowers. Deer and rabbits, however, don't care for the taste of the leaves or stems. Plant in full sun and water it well the first year to get the root system established. Thereafter, it rarely needs supplemental watering.
