ケヤキ
"Zelkova serrata" is planted as a lawn or park tree for its attractive bark, leaf color and vase shape. It provides good shade and has an easy fall cleanup. It is easy to transport, and often available in burlap form. It is also commonly used for bonsai; its attractive shape and colors make it a popular choice for the art. It is often grown as an ornamental tree, both in its native area and in Europe and North America. The first cultivation outside of Asia was by Philipp Franz von Siebold, who introduced it to the Netherlands in 1830. Recently, it has been planted as a "street tree" in New York City. In the UK it has gained the Royal Horticultural Society's Award of Garden Merit.
