Aloe elgonica is an attractive succulent that forms clumps of erect or decumbent stems, each topped by a rosette of glossy, medium-green leaves. It grows up to 90 cm tall. The rosettes can reach a diameter of 30 cm. Leaves are recurved with deltoid teeth along the margins. They are blushed with pink when first emerging.
Flowers are bright red and appear in densely flowered racemes on a simple or branching inflorescence from late spring to mid-summer.
Aloe elgonica is native to Kenya. It occurs from 6,500 to 7,800 feet (1,980 to 2,380 m) on Mount Elgon.
