Buddleja (Buddleia) are a varied group of plants with a variety of flower and foliage forms. Over 20 species and 100s of named cultivars are available.
Popular species include Buddleja crispa, salvifolia, the yellow flowering Buddlea weyeriana, and B. colvilei. Both deciduous or evergreen varieties are available with the deciduous species being a little more hardy in cooler climates.
