Cycas Palm


 Cycas revoluta (sago cycad), is an attractive plant native to southern Japan. Though often known by the common name of king sago palm, or just sago palm, it is not a palm at all, but a cycad.

This very symmetrical plant supports a crown of shiny, dark green leaves on a thick shaggy trunk that is typically about 20 cm (7.9 in) 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 (over 20 feet) 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.

The leaves are a deep semi glossy green and about 50–150 cm (20–59 in) long when the 
plants are of a reproductive age.
 
Propagation of Cycas revoluta is either by seed or by removal of basal offsets. As with other cycads, it is dioecious, with the males bearing cones and the females bearing groups of megasporophylls. Pollination can be done naturally by insects or artificially.

ZZ makes a great room accent and practically thrives on neglect. This easy-going house plant is forgiving if you forget to water, tolerates low light, and rarely needs fertilized. Want more? It also seems to shrug off pests. Growing from rhizomes, it has thick, upright stems bearing narrow, dark-green glossy leaves. Keep the leaves clean by gently wiping them with a damp cloth. Don’t use leaf shine products, which can damage the plant. Small, insignificant flowers — consisting of a spadix surrounded by a spathe — may appear at the base of plants in summer, although ZZs rarely flower indoors. A slow-grower indoors, ZZ plant rarely needs
