Huernia bayeri is an interesting multiple stem species with plump stems mall tubercles along the ribs that resemble teeth. Readily offsets to form large low growing mounds. The flowers, which arise in succession at the base of the stems, are cup-shaped, with creamy white to dull yellow petals unspotted or sometimes finely spotted with red, the coronas at the centers of the flowers are dark purple.
This plant isn't difficult to grow and flower. They will tolerate very hot weather outdoors as long as they are kept in filtered light and this will encourage them to flower in the Autumn.
