The plants of the genus Frithia are sunk into the ground and grow in compact rosettes of up to 30 millimeters in diameter. The alternate leaves are club-shaped and have an almost flat tip with a transparent window. Its rough surface is almost completely covered with a layer of wax.

The individual, mostly sessile flowers reach a diameter of up to 35 millimeters. There are five unequal sepals that have grown together to form a short, cup-shaped tube. The numerous, purple to white petals are arranged in several whorls and fused together at the base. The thread-like staminodes surround three circles with stamens . The five-part stigma has short, sharply pointed carpels .

The plants bloom in their homeland from October to February. The flowers open in the late morning and close again in the late afternoon.
