Koto-No-Ito translates to Harp Strings, perfectly describing the exceptionally thin, thread-like green lobes of its foliage. The spring leaves emerge with a delicate light green hue often brushed with soft bronze tips. As summer progresses, the fine texture creates a bamboo-like, graceful appearance in the garden. Autumn completes the season with a brilliant transformation into bright golden-yellow tones. Its unique texture provides wonderful contrast against broad-leaved plants.

Growth Habit & Size
Upright
Upright tree with very fine strap-like foliage.
What do these growth habit terms mean?
More than one term can apply. Branch direction, crown shape and size describe different characteristics, and the outline can change as a tree matures.
Upright
Main stems and branches emphasize upward growth. An upright tree can still develop a broad canopy.
Spreading
Branches extend outward to form a broad canopy. The tree does not have to be wider than it is tall.
Weeping
Branches or branchlets arch or hang downward. The tree can still have an upright trunk.
Rounded
The crown has a rounded outline. This describes the overall shape rather than the direction of each branch.
Dwarf
A cultivar with a smaller natural stature than typical forms of its species. Dwarf describes size, not branch direction or a fixed height limit; it does not automatically mean slow growth.
For example: Bloodgood can grow upright while developing a broad, rounded canopy with spreading branches.
'Koto-No-Ito' is a Japanese maple associated with nurseryman Koichiro Wada. Seattle Japanese Garden explicitly credits Wada with naming and introducing it in Japan in 1938, and Γrable du Val de Jargeau likewise attributes the 1938 introduction to his nursery. These accounts document introduction rather than the original selection event; they do not establish who first selected the plant or when. Maple Ridge Nursery also credits Wada with naming it for its narrow, straplike foliage. Commonly translated as 'harp strings,' the name evokes the slender leaf lobes. Seattle Japanese Garden describes an upright, vase-shaped tree whose fine spring foliage becomes green, followed by golden autumn color. No verified parentage, controlled cross, or original collection accession was located.
