[The text below was prepared by SJG Plant Committee for docent maple training in fall 2013]

One grows in area ZZW, near the beginning of Area U and the path from the Tea House.

Acer nikoense can grow to 30’ to 45’ tall. It has dark gray to blackish bark. The trifoliate leaves are 4” long by 2” wide. They turn a pinkish-red color in late autumn and the three lobes separate as they fall.

The Nikko maple was first introduced to cultivation in1881, when seeds were imported by the Veitch Nursery in England after being discovered by Charles Maries in the forests of Hokkaido. It was grown for its medicinal uses including treatment for liver disease and acute and chronic eye disease at the Buddhist temple Tsubosaka Dera over 400 years ago. It is again being investigated for its use in traditional medicine.

Nikko maple is known as megusuri-no-ki, meaning “eyes medicine.”

SJG • 10/22/13 – Acer nikoense aka Acer maximowiczianum •  Nikko Maple, Area ZZW, bordering on orchard area (red tree in middle of the picture, lined up with the lantern). Our nikko maple doesn’t seem to have the typical bushy spread of this specimen, probably because of competition with nearby trees.

From wikipedia: Acer maximowiczianum (Nikko maple; syn. A. nikoense Maxim.)[…] Many older texts refer to the species under its synonym A. nikoense Maxim., but as Maximowicz had also cited the name Negundo nikoense Miq. in synonymy, his new name had to be regarded as the same as that under the ICBN. Miquel pointed out that his Negundo nikoense was actually a different plant to the maple Maximowicz had intended to describe, and therefore gave the Nikko Maple a new name, honouring Maximowicz in the process.

From a Tree a Day (Best Trees for Australia – a great website for tree descriptions and needs): […] The leaves are handsome enough all summer long but, being a maple, they turn spectacular shades of orange and red making the Nikko maple the centrepiece of the autumnal garden. […] Nikko maple does not like long, hot summers nor deep, bitter winters. It will grow across the United Kingdom and across the middle of the United States,  It also does well in New Zealand and temperate Australia. […]
