Frithia is a small genus with 2 perennial succulent species that grow from rosettes. Native to dry, rocky habitats in the Gauteng Province of South Africa, these are commonly grown as houseplants. This genus possesses specialised leaf structures called epidermal windows, which are translucent sections in the leaves. These are an adaptation to the dry environments they evolved in, allowing for efficient photosynthesis from beneath the soil surface, where they are well protected from drying winds and the worst of the sun's heat. Flowers are large, daisy-like and brightly coloured, in shades of pink, purple and white, with yellow centres.
