Long Spiked Butterfly Bush is a tall shrubs or small trees, 1-6 m tall,
native to China, Bangladesh, India, Thailand and Vietnam. Stems are
noticeably winged, square, brown striped and exfoliating. Leaves are nearly
stalkless - leaf blade narrowly to very narrowly elliptic, 4-45 X 1-15 cm.
Leaf margin is crenate-serrate, and tip sharp. Mature leaves are dark green
and very large up to 10 inches in length at maturity. Dense flower spikes
occur at the end of branches. Compared to the more common
Butterfly Bush, they are long,
5-20 X 2.5-4 cm. Flowers are small, cream colored, with an orange-red
throat. The four petals are sort of roundish in shape. Long Spiked
Butterfly Bush is found on mountain slopes, river banks in forests, at
altitudes of 900-3200 m.
