About
Aloe rauhii is a stemless succulent that maintains its foliage year-round. It features rosettes of elongated, thick leaves that are a grey-green hue, adorned with lighter green patterns and small white serrations along the edges. In bright sunlight, the leaves may develop a brown tint. During the summer, it produces small, tubular flowers that are pinkish-red, borne on stalks that can reach up to 30 cm in height.
