About
Acer palmatum, commonly known as Japanese maple, palmate maple, or smooth Japanese maple (Korean: danpungnamu [단풍나무]; Japanese: irohamomiji [イロハモミジ] or momiji [紅葉]), is a species of woody plant native to Korea, Japan, China, eastern Mongolia, and far eastern Russia. Many different cultivars of this maple have been selected and they are grown worldwide for their large variety of attractive forms, leaf shapes, and spectacular colors.
How to grow it
Acer palmatum has been cultivated in Japan for centuries and in temperate areas around the world since the 1800s. The first specimen of the tree reached Britain in 1821.
When Swedish doctor-botanist Carl Peter Thunberg traveled in Japan late in the eighteenth century, he produced drawings of a small tree that would eventually become synonymous with the high art of oriental gardens. He gave it the species name palmatum after the hand-like shape of its leaves, similar to the centuries-old Japanese names kaede and momiji, references to the 'hands' of frogs and babies, respectively.
