The true sago palm, scientifically known as Cycas revoluta, is a perennial, evergreen plant belonging to the family Cycadaceae. It is native to the southern regions of Japan, particularly on the islands of Kyushu and Ryukyu.
The true sago palm is a striking and slow-growing plant, typically reaching a height of about 3 to 6 feet (1 to 2 meters) in cultivation, although it can grow much taller in its natural habitat. Its trunk, covered with coarse and persistent leaf bases, emerges from a crown of long, glossy, dark green leaves that grow in a circular, whorled arrangement. These leaves are pinnately compound, reaching lengths of 2 to 5 feet (60 to 150 cm), and consist of numerous narrow leaflets with pointed tips.
The true sago palm is dioecious, meaning there are separate male and female plants. The female plants produce large, cone-like structures known as cycad cones, which contain seeds covered in a reddish-brown outer layer reminiscent of pine cones. These seeds are toxic if ingested due to the presence of cycasin, a naturally occurring toxin.
Due to its attractive appearance and ability to tolerate various growing conditions, the true sago palm has become a popular ornamental plant worldwide. However, it is important to note that the true sago palm should not be confused with the unrelated sago palm species, Metroxylon sagu, which is a tropical palm known for its starchy pith used in culinary preparations.
