Crassula perfoliata var. falcata, known as the airplane plant or airplane propellers, has gained the Royal Horticultural Society's Award of Garden Merit.[3] Growing to 1 m (3.3 ft) tall and broad, this succulent evergreen subshrub has grey erect leaves and scarlet flowers in summer. As it does not tolerate freezing temperatures, in temperate zones it must be grown under glass using a cactus compost.
