Propeller Plant is a succulent with thick, grayish-green leaves arranged in a spiral around upright stems. Their opposing shape resembles a propeller. Mature plants may develop clusters of tiny red flowers during summer. Its geometric foliage suits sunny windows and succulent collections. It is easy to maintain when given strong light, fast-draining soil, and complete drying between waterings.
