Sansevieria starfish succulents thrive indoors in bright indirect sunlight and planted in well-draining sandy soil. Cylindrical snake plants need water only when the potting mix is dry. As with most succulent plants, sansevieria starfish plants don’t require extra indoor humidity. Grow in average room temperatures and fertilize monthly during the growing season. Cylindrical snake plants are succulents with long fleshy, tubular leaves. The rod-like succulent leaves are a greenish-gray color with darker stripes wrapping around the cylinder leaves. The Sansevieria cylindrica species grows tube-like leaves up to 7 ft. (2 m) tall.
