Description

Botanical illustration of Trichodiadema barbatum (as Mesembryanthemum barbatum)
Trichodiadema barbatum in cultivation

A small, gracile, erect-to-decumbent plant, with long, slender, fragile, stick-like branches. The internodes are minutely papillate; On young branches the internodes are green, becoming grey on older branches.[4]

The grey-green leaves are slightly triangular in cross-section, and have large bladder cells on their leaf-surface. Bristles (5-7) emerge from the dark tip of the leaf.

The solitary, bright pink-to-purple flowers are born on long pedicels. They have petals with slightly notched apices, small pale filamentous staminodes, and yellow anthers.

The fruit capsule is 5-locular, like that of Trichodiadema burgeri (but unlike some other species in the genus, such as Trichodiadema densum and Trichodiadema marlothii.[5][6]

It has gained the Royal Horticultural Society's Award of Garden Merit.[7]
