Trichodiadema strumosum is succulent plant of the genus Trichodiadema, native to the Western Cape Province, South Africa, where it is found in loam-based soils in the Fynbos vegetation of the Swellendam region.

It is also one of three species that have leaves entirely covered in dense hairs (together with T.fergusoniae and T.pygmaeum).

Its growth form is erect to partially decumbent (but not mat-forming like T.pygmaeum).

In its general growth-form, it is most similar to T.gracile, which differs in having leaves with bead-like epidermal cells and not hairy.

The flowers are pale apricot coloured, each petal with a deep purple line along the centre.
