Cycads revoluta, one of the most primitive living seed plants, are a very unusual and popular ornamental. A rugged trunk, topped with whorled feathery leaves has lead to the common name ”Sago Palm”, however it is actually related to conifer and Ginkgo trees - all cone bearing plants which trace their origins back to the ancient flora of the early Mesozoic era. Often called ”living fossils”, Cycads have changed very little in the last 200 million years.
While various species of Cycads can be found throughout the world, the sub-tropical Cycads revoluta is native to the Far East and has been used as a choice container and landscape plant for centuries. The growth habit of Cycads revoluta displays an upright trunk with a diameter from 1” to 12” depending on age, topped with stiff feather-like leaves growing in a circular pattern. Rather than continuously adding foliage, Sagos produce a periodic ”flush” of new leaves, called a ”break”,. Eventually, offsets begin to grow at the base of the specimen, and occasionally in the crown. The addition of offsets provides a source of new plants and many possibilities for developing a unique specimen.
Regardless of age or size, Cycads revolta is one of the easiest plants to grow, indoors or out, by beginner or expert. This subtropical adapts to a wide range of temperatures from 15° - 110° F (-11 - 42° C). Accepts full sun or bright interior light, thrives with attention, and tolerates neglect. In addition, Cycads are extremely long-lived. |
