Pugster White® (‘SMNBDW’) Butterfly Bush is a compact but sturdy Buddleia, with large fragrant white flowers. The short stature means that the Buddleia x Pugster White® does not need the pruning that earlier large cultivars have required. Also, the Pugster® series is somewhat more cold tolerant than several earlier Buddleia cultivars. This would make a good potted plant for sunny patios in summer.
