ケヤキ
Though he is well known in Japan, where he is called "Shiboruto-san", and although mentioned in the relevant schoolbooks, Siebold is almost unknown elsewhere, except among gardeners who admire the many plants whose names incorporate "sieboldii" and "sieboldiana". The Hortus Botanicus in Leiden has recently laid out the "Von Siebold Memorial Garden", a Japanese garden with plants sent by Siebold. The garden was laid out under a 150-year-old "Zelkova serrata" tree dating from Siebold's lifetime. Japanese visitors come and visit this garden, to pay their respect for him.
