Fountain butterfly bush (Buddleia alternifolia, zones 5 to 9) is a bigger cousin of the more familiar butterfly bushes. Unlike those, this blooms with a frothing fount of lavender in spring, hence its name. Fountain butterfly bush blooms on last year's wood, so prune it only right after it flowers. This drought-resistant shrub likes sun and lean soil, and its silvery leaves make it interesting throughout the growing season. Cultivar 'Argentea' is even more silver.
