Oldenburgia grandis is a shrub or small, gnarled tree in the family Asteraceae.

It has thick corky bark and large leaves clustered at the ends of branches.

The emergent leaves are densely and completely felted with white hair.

Most of the felt is lost as the leaf matures, but some persists on under-surfaces.

Flowers are white or purplish and borne in large heads some 5- to 12 cm in diameter.
