Vegetative characteristics

Aloe officinalis grows like a trunk, usually sprouts and forms dense clumps. The trunks are prostrate and short. The ten to twelve, sword-shaped, narrowed leaves form dense rosettes . The yellow-green leaf blade is about 60 to 70 inches long and 6 to 12 inches wide. It is often spotted white. On the underside, there are occasionally up to nine spines in the middle. The leaf surface is smooth. The strong teeth on the edge of the leaf are huddled together.

Inflorescences and flowers

The inflorescence is simple or consists of one to three branches. It reaches a length of up to 100 centimeters. The loose, cylindrical grapes are 15 to 20 centimeters long. The egg-shaped-pointed or lanceolate bracts have a length of 10 millimeters. The slightly club-shaped, red or yellow to orange-colored flowers are on 6 to 8 millimeter long peduncles . The flowers are 28 to 30 millimeters long. Your outer tepals are not fused together over a length of about 15 millimeters. The stamens and the stylus barely protrude from the flower.
