Aloe delphinensis grows trunk-forming, branches out from the base and forms loose groups. The upright or rising shoots are up to 30 centimeters long and 1 centimeter wide. The linear leaves are scattered along the shoots. Their green to red-green leaf blades are 15 to 25 inches long and 1.5 inches wide. The reddish teeth on the leaf margin are small and crowded. The leaf sheaths are about 1 inch long. They are red-brown and have darker veins.
Inflorescences and flowers
The simple inflorescence is 18 to 28 inches long. The loose, cylindrical grapes are about 8 inches long and 6 inches wide. They consist of about 15 flowers . The red-brown, triangular bracts have a length of 2 millimeters. The red flowers become whitish towards their tip and have greenish central ribs. They stand on 15 to 18 millimeter long flower stalks that are almost horizontal in the bud stage. The flowers are 25 millimeters long and above the ovary very slightly narrowed. The stamens protrude slightly and the pen does not protrude from the flower.
