Crassula perfoliata var. falcata (Propeller Plant)

Crassula perfoliata var. falcata, commonly known as Propeller Plant or Airplane Plant, is a distinctive succulent in the Crassulaceae family native to South Africa. It forms upright to sprawling stems, typically 1-2 feet (30-60 cm) tall, bearing thick, gray-green leaves arranged in opposite pairs. The flattened, slightly curved, sickle-shaped leaves resemble propeller blades and often develop reddish margins or a reddish flush in strong light. In summer, mature plants produce dense terminal clusters of numerous small, brilliant scarlet to orange-red flowers, creating a striking contrast with the muted foliage.

Crassula perfoliata var. falcata grows best in full sun to bright filtered light and sharply drained soil. It is drought tolerant once established and should be allowed to dry between waterings, particularly during cooler weather. The plant performs well in containers, succulent gardens, and rock gardens and is easily propagated from stem or leaf cuttings. Hardy in USDA Zones 9-11, it should be protected from prolonged frost and excessive winter moisture. The variety was formerly widely treated as a separate species under the name Crassula falcata; this name remains extremely common in horticulture and is useful to retain as a synonym, although Crassula perfoliata var. falcata is now the accepted botanical name.
