Buddleja glomerata, commonly known in Afrikaans as Karoosalie (Karoo salvia), is a straggling shrub or small tree that reaches 4 m in height (SA Tree List No. 636.1).
B. glomerata is grown for its attractive foliage. The leaves are oblong with notably wrinkled and puckered surfaces and scalloped margins. Leaf dimensions are from 1,2 cm to 6 cm long and 0,2 cm to 2,6 cm wide. The young leaves are silvery, hairier below than above. They turn blue-green as they mature.
The flowers are small and yellow, growing in rounded heads at stem tips. The fruit is a small, hairy capsule.
the species distribution is in the centre and south of South Africa, in the Western Cape, the Northern Cape and the Eastern Cape.
The habitat is rocky, karoid slopes. The species is not considered threatened in habitat early in the twenty first century (Coates Palgrave, 2002; www.plantzafrica.com; http://redlist.sanbi.org).
