Buddleja crispa, commonly known as the Himalayan Butterfly Bush, is native to  the Himalayas region, including north India, Afghanistan, Pakistan and south China. In its native habitat it grows in rocky slopes, exposed cliffs and thickets.

The etymological root of the binomial name Buddleja is named after Adam Buddle (1662-1715), an English botanist. Crispa is from the Latin meaning ‘wrinkled’, in reference to its leaves.

The landscape architect may find Buddleja crispa useful as a fragrant summer flowering shrub. This plant is most successful when grown against a wall. Once established this shrub is drought tolerant.

Ecologically, Buddleja crispa flowers are very attractive to nectar loving insects and birds.
