Buddleja axillaris is a shrub endemic to Madagascar, the Comoro Islands, and Tanzania, growing in forests at elevations of 3001400 m. The species was first named and described by Willdenow in 1827.[1]

Description

Buddleja axillaris is a sarmentose shrub 23 m in height, with quadrangular branchlets, often obscurely winged, and white-pubescent. The opposite leaves have thinly coriaceous ovate to narrowly elliptic blades, 630 cm long by 210 cm wide, acuminate or apiculate, abruptly narrowed at the base, minutely pilose above, but white-tomentose to subglabrous beneath, with mostly shallow crenate - dentate margins. The slender white or occasionally yellow inflorescences are axillary, solitary and thyrsoid 314 cm long by 14 cm wide, the corollas 517 mm long.[2]

The species is considered closely related to B. cuspidata and B. sphaerocalyx.

Cultivation

Buddleja axillaris is not common in cultivation. Hardiness: USDA zone 10.[3]
