About plant names...

Butterfly bush is native to the Sichuan and Hubei provinces in central China, and has become a popular ornamental plant in North America. Butterflies find it irresistable. It has become naturalized in North America.

Plants: This shrub can reach 6-13' (1.8-4 m) in height, and can reach 15' (4.6 m) around. It has arching stems.

Leaves: Opposite, lanceolate, gray-green, finely toothed, 2½-8" (7-20 cm) long. Young leaves have fine hairs beneath.

Flowers: Spectacular roughly conical panicles at branch tips are up to 8-18" (20-45 cm) in length, with numerous tiny purple tubular flowers with orange centers. (Other color combinations have been cultivated as well, including lilac, dark purple, pinks, yellows, whites, reds, and almost black.) They appear from June to September.

Fruits: Each flower becomes a 2-valued seed capsule con­tain­ing about 50 seeds.
