An evergreen tree growing to 11ft at a slow rate, possibly even taking 50 years to attain this height. It is a symmetrical plant that produces a crown of shiny, arching, palm-like, evergreen palmate leaves atop a shaggy upright trunk. Trunks take a long time to form. Each leaf has a large mid-rib with very narrow, rigid, spiny-tipped, deep green leaflets. Leaflets have revolute edges (margins rolled downward), hence the specific epithet. Young sago palm plants produce leaves intermittently in several different growth spurts per year, however mature plants only produce leaves once per year.
It flowers from May to July, and the seeds ripen from October to November. The species is dioecious, meaning that individual flowers are either male or female, but only one sex is to be found on any one plant, so both male and female plants must be grown if seed is required. It is pollinated by insects and wind. The plant is not self-fertile.
**WARNING – Highly toxic to dogs.
