Crassula falcata, known by the common names airplane plant and propeller plant, is a succulent plant endemic to South Africa, from the Cape of Good Hope. The foliage is gray-green with striking texture, on plants that grow to 2 feet (0.61 m) tall. The flowers are tiny and scarlet red, that rise in dense clusters above the foliage for a month in summer. Crassula falcata is cultivated for use in drought tolerant and succulent gardens, and in container gardens.
