'Nanho Purple' is a compact buddleia, growing about 3 to 5 feet tall and wide (it will be on the lower end of that if you prune it back hard in the spring). flowers are fragrant, lavender-purple, and bloom from June to August. This is a great buddleia for perennial borders or smaller spaces, or planted in from of taller grasses for a fabulous late-summer show. Attracts bees, butterflies, and hummingbirds; deer resistant.
Buddleia flower on new wood, so a hard pruning in late winter to early spring will encourage alot of branches and alot of flowers. Buddleia sometimes die-back in our colder winters, so prune hard to remove dead wood. If you want to try to keep your buddleia taller, when you prune, cut off the outward, arching branches, leaving the taller, central limbs in place. Attractive to bees, butterflies, and hummingbirds; resistent to deer. Grow in full sun to part shade, but best flowering occurs with full sun. Grow in well-drained soil; adaptive to soil types, from poor, dry soils to sandy-loam and clay-loam soils. A great cut flower.
