Leaves and male cone of Cycas revoluta
Species: C. revoluta
Cycas revoluta, the Sago Cycad, is a cycad native to southern Japan, but is now grown worldwide. It is known in some African cultures as the Bread Tree. Though often known by the common name of King Sago Palm, or just Sago Palm, it is not a palm at all, but a type of gymnosperm.
This very symmetrical plant supports a crown of shiny, dark green leaves on a thick shaggy trunk that is typically about 20 cm in diameter, sometimes wider. The trunk is very low to subterranean in young plants, but lengthens above ground with age. It can grow into very old specimens with 6-7 m of trunk, however, the plant is very slow-growing and requires about 50-100 years to achieve this height. Trunks can branch multiple times, thus producing multiple heads of leaves.
Cycas revolutaThe leaves are a deep semiglossy green and about 50-150 cm long when the plants are of a reproductive age. They grow out into a feather-like rosette to 1 m in diameter. The crowded, stiff, narrow leaflets are 8-18 cm long and have strongly recurved or revolute edges. The basal leaflets become more like spines. The petiole or stems of the Sago Cycad are 6-10 cm long and have small protective barbs that must be avoided.
Propagation of Cycas revoluta is either by seed or by removal of basal offsets. As with other cycads, it is dioecious, with each specimen bearing either male or female cones. Pollination of receptive female cones can be done naturally by insects or artificially.
