description
Vegetative characteristics
Gasteria bicolor grows trunk-forming, is prostrate to upright and reaches a height of 8 to 50 centimeters. It sprouts from the base and forms small groups. The leafy trunk reaches a length of up to 20 centimeters. The upright, slightly sickle-shaped, ribbon-shaped to linear leaves are arranged in two rows on the shoot or form a rosette . The dark green leaf blade is 8 to 46 inches long and 1.5 to 6 inches wide. It is densely covered with white spots arranged in indistinct diagonal stripes. If the leaves are arranged in a spiral, they are asymmetrically keeled. The epidermis is smooth and rarely slightly rough. The finely serrated and sometimes entire leaf margin is cartilaginous. The bluntly rounded tip of the leaf is rarely pointed and has an asymmetrical tip. Young leaves are spreading or spread out upright, band-shaped, rough, bluntly rounded and have an attached tip.
Inflorescences and flowers
The inflorescence is seldom simple and has up to eight upright branches. It reaches a length of 10 to 150 centimeters. The light pink, rarely white flower envelope is 12 to 20 millimeters long. Your bulbous part is spherical to spherical-ellipsoidal. It extends over half the length of the flower envelope and has a diameter of 6 to 9 millimeters. Abruptly it narrows to a white, green-striped tube with a diameter of 3 to 4 millimeters.
The flowering time is spring.
