Produces pairs of attractive and interesting sickle shaped grey-green leaves, but a show stopper when the bright red flowers emerge. The flower smells like sweet cinnamon and usually lasts 6-8 weeks.
Sometimes they bloom twice a year, and the bees really love the flowers too.

Description: Crassula perfoliataSN|11182]]SN|11170]] var. falcata (The 'Propeller Plant' or 'Airplane plant') make a lovely clump/low growing shrub, that usually grows less than 60 cm tall (but some sources say 1.2 m of height). It has very peculiar grey-green sickle-shaped leaves that are arranged in overlapping pairs along a usually unbranched stem. Tiny scarlet red flowers are massed together in very showy dense clusters that rise above foliage in mid summer. The flowers open slowly and last for nearly a month when in full bloom. Another common name used for this plant is Scarlet Paintbrush, refering to the beautiful flowers.
Stem: Usually unbranched above (but forming new shoots at the base), succulent becoming woody in age.
Roots: Fibrous.
Leaves: Interesting glaucous grey-green arranged in overlapping pairs, leaves are propeller shaped (sickle shaped), decussate, ascending, becoming spreading, lanceolate, slightly falcate, smooth, upper face flat, channelled at the base, margins acute toward the apex, truncate lower down, lower face convex, tip recurved and acute, mucronate up to 10 cm long, 2-3 cm wide. These leaves radiate outward in opposite directions like wings, which gives the plant the common name "Airplane Plant".
Flowers: Spectacular clusters of tiny bright orange-red or scarlet-red florets arranged in dense cymes, that rise above foliage. Flower heads grow 8 to 12 cm wide and are scented.
Blooming season: Flowers starts to develop in June and are in full bloom in August. The flowers open slowly and last for nearly a month when in full bloom.
Taxonomy: This plant, long grown as Rochea falcataSN|11184]]SN|11184]] and then Crassula falcataSN|11170]]SN|11182]] is now correctly named Crassula perfoliataSN|11182]]SN|11170]] var. minor though in cultivation it continue to be listed is a Crassula falcataSN|11170]]SN|11182]] as this name is better recognized.

- Crassula perfoliata L.: (var. perfoliata) is little branched up to 1.3 m high, with lanceolate leaves erect and channelled above. The flowers are small, white and appear in the summer. Distribution: north of Port Elizabeth to Graaff-Reinet and Willowmore.
- Crassula perfoliata var. coccinea (Sweet) G.D.Rowley: has the red, larger flowers but its leaves are lanceolate-triangular, canaliculate and erect to spreading. Distribution: river valleys between Port Elizabeth and King William's Town.
- Crassula perfoliata var. falcata (J.C.Wendl.) Toelken: (syn: Crassula perfoliata var. minor) has very peculiar grey-green sickle-shaped leaves that are arranged in overlapping pairs along a usually unbranched stem. Flowers are bright red. Distribution: Eastern Cape.
- Crassula perfoliata var. heterotricha (Schinz) Toelken: is smaller (40 cm tall) and branched with erect leaves, has small white flowers appearing in the winter. Distribution: Umtata northwards through KwaZulu-Natal and Transvaal to south-east tropical Africa.

Attractive and interesting when not in bloom but a show stopper when the bright red flowers emerge.
Soil: It needs well drained soil (standard cactus potting mix).
Waterings: Requires very little irrigation in coastal gardens, irrigate occasionally in hotter inland climates. In pots needs regular wateringsall year, but reduce watering during winter month and apply a balanced liquid fertilizer during the summer months (June, July, August).
