Scientific Name

  Sciadopitys verticillata  Siebold &  Zuccarini (Sciadopityaceae, Cupressales)

Inventory Numbers: 724

The Japanese umbrella pine(Sciadopitys verticillata)get its common name from the long needlesthat radiate from nodes outward like ribs of an umbrella. The tree is native to Japan where fossil evidence dates it back 230 million years. It was probably introduced to the United States at the end of the 19th century. The female cones have chunky scales. Despite its name, the tree is neither a spruce nor a pine and is classified these days as a unique conifer. Young trees have a pyramidal shape while mature trees look more like white pine trees. The genus name Sciadopitys is derived from the Greek skidos – whorl, and pitys – a fir tree. Listed as a vulnerable species due to harvesting for its water-resistant wood used for boat making. The Japanese umbrella pine is a popular garden plant in Japan. Though a slow grower, it is hardy and grows well in cold climates.
