description
Sansevieria ehrenbergii grows stemless or as a stem-forming perennial, succulent plant with rhizomes around 3 centimeters thick . The trunk is upright to 25 centimeters high. The five to nine succulent leaves on a shoot are arranged in two rows, arranged in a fan-like manner, upright or spread out and pressed together at the sides with a triangular groove along the top. The simple leaf blade is 76 to 180 inches long and 3 to 4.5 inches wide. It is dark green with five to twelve blackish green, flat longitudinal grooves. Above the middle it suddenly changes into a 6.5 to 20 millimeter long, very hard, thorny spade tip. The spreading edge is reddish brown with a white membrane-like edge. The leaf surface is slightly rough. In the case of seedlings, the leaves are short and do not initially have two lines.
The paniculate inflorescences are up to two meters high. The panicles are densely populated with four to seven flowers per cluster. The flower stalk is 2 to 4 millimeters long. The bracts are purple to white. They have a 5 to 6.5 millimeter long tube.
