Butterflybush is a deciduous shrub that is 3-15 ft. (1-5 m) tall with arching stems. The leaves are opposite, 6-10 in. (15-25 cm) long, velvety and lanced-shaped. Flowering occurs from May to August, when dense clusters of tubular flowers develop. These flowers can be purple, white or pink and have 4 petals. The flowers produce high quantities of nectar and are attractive to butterflies, hence the common name. Butterflybush is native to southwestern China and was introduced into North America around 1900. It prefers disturbed sites and riparian areas. |
