The African spear plant (Sansevieria cylindrica), also known as the cylindrical snake plant, is a succulent that consists of upright, gray-green, subtly striped leaves. The leaves are cylindrical in shape but narrow to a point at their tips. When grown in optimal conditions, African spear plants might send up a long flower spike from their center that’s full of tiny, delicate, white blooms. They are best planted at the start of the growing season in the spring, and they’re generally a slow-growing succulent. The mature Sanseveria Cylindrica grows up to 4–6 ft. tall and 1–2 ft. wide.
African spear plants are generally very low maintenance. They will survive if you forget to water or feed them, and they can thrive being root-bound in a pot. During the growing season (spring to fall) they will appreciate semiregular watering and occasional fertilizing. These plants can tolerate somewhat low light conditions, but they prefer some full sunlight along with bright filtered light. Too strong of light can cause the leaves to yellow around the edges, and too little light can result in subpar leaf growth.
Like most succulents, these plants prefer a sandy soil that has excellent drainage and doesn’t retain water. A potting mix made especially for succulents is ideal. African spear plants can survive long periods of drought. And being left in soggy soil or standing water for too long can cause the roots to rot. These succulents grow naturally in hot, dry climates, and cold temperatures can damage or kill them.
