Buddleia Davidii Dapper Lavender Portfolio Butterfly Bush is a deciduous shrub that grows in a mound with short branches and dense gray-green foliage. Early in the summer and continuing into the fall, the long, light purple panicles bloom on short stems close to the foliage, luring bees and butterflies. Dapper Lavender Butterfly Bush prefers full sun and well-drained soils for proper growth. It is ideal for accents, borders, foundations, hedges, and containers.
