Maintains a feathery-pyramidal growth habit. Branches grow almost horizontally. Fine in leaf, less so when defoliated. Contains 5-9 winged seeds. Cones ripen in early December and shed their seeds in late December and early January.
Seed wings are minute.
Seldom requires pruning due to neat, uniform, conical habit. Good for screening. About 5 days. The genus was first discovered from fossils by Miki in Japan. Later they we found growing wild in China.
