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 (www.plantzafrica.com; Coates Palgrave, 2002).
