- History & LoreHistory:This species, A. palmatum, may be the most widely bred of the Acer clan. It is credited to Carl Thunberg, 1743-1828, the physician and plant collector working for the Dutch East India Company in Japan. It is likely he collected the first plants, for they were classified after his return to Europe in 1820. Although called Japanese maple, this species is native to China and Korea as well. There are an immense number of cultivars produced by this highly variable species. This form was introduced by Monrovia Nursery Co. Azusa, California in 1998. Its dark red coloring identifies it among the Atropurpureum group, which were first developed from A. p. 'Atropurpureum' after 1857.Lore:The Japanese maple is the quintessential symbol of fall in the traditional Tea Garden, balanced by flowering cherries for spring.
