See text Trichodiadema is a genus of succulent plants of the family Aizoaceae.

The name "Trichodiadema" comes from the ancient Greek "τρῐχός" (hair, bristle) and "διαδεμα" (crown).

At the apex of each alternating section is a ring of small bristles radiating around the center, that give the appearance of a cactus areola.

The flowers look like daisies, with red, pink or white petals, earning them the nickname "Desert Rose".

Trichodiademum densum has gained the Royal Horticultural Society's Award of Garden Merit.
