The Sago Palm Tree, scientific name Cycas revoluta or Cycas revolut, is a unique plant that resembles a palm tree but is actually a cycad. It is a great palm for landscape in USDA zones 8-11. The Sago Palm is also known as Japanese Sago Palm, King Sago Palm, and Sago Cycas.
Cycas revoluta is a very slow growing palm that can get up to 15ft tall. Young specimens have thick shaggy subterranean trunk 8-10 inches in diameter. It could take 70-100 years for the Sago Palm to reach its maximum height. Trunks can branch multiple times, creating multiple heads of leaves. As the palm matures it might produce suckers at its base forming a large multi-stem clump over time.
The Sago Palmhas pinnate, or feather-like, leaves that are 4-5ft long and 10 inches wide. The Sago Palm Tree is a very symmetrical plant with fronds growing in a circular pattern creating a rosette. Leaves are dark green, glossy, with stiff, pointed leaflets. Leaflets are narrow, only 4-7 inches long and have strongly recurved edges. In late spring or early summer, sagos produce a light green spikes of new leaves, called a ‘break’. They slowly unfold growing to the ultimate length of the leaf.
It takes Sago Palm around 13 years to start to bloom. The Sago Palm is dioecious, meaning that each plant is either male or female. The female inflorescence is feather like, later forming a tightly packed seed head, closely covered by whitish miniature leaves. The male cone is pineapple shaped. When it is time to pollinate, females sagos begin to flower and male sagos produce cones.
