Acer palmatum Koto no ito in Japanese means ‘Harp Strings’ because of the thin green leaves. It is also nicknamed the ‘Dancing Monkey Tree’ because the leaves hang down and whip around when the wind blows. Another great characteristic of this maple is the change in leaf size as the maple matures. The newest leaves emerge fatter compared to the older leaves on lower branches. As the maple ages, subsequent leaves become thinner, more linearilobum in nature. Koto no ito can handle full sun to partial shade.
Koto no ito grows to around 6-7′ tall and 4′ wide in 10 years. The growth habit is like a ‘vase or V-shape’. Branches that grow between the V shape of the maple should be removed to allow for air flow and to reduce the number of dead leaves that get stuck during the fall and winter. Dead leaves that remain on maples can cause mold or mildew issues. For more information please see Pruning Japanese Maples.
Koto no ito is a lovely green maple spring and summer. Then as temperatures fall and days become shorter the maple is stressed which creates the fantastic fall color which evolves from gold to orange to scarlet. This small shapely maple is ideal for a small garden or patio container. Once established this cultivar is hardy to USDA zone 5.
If you love Japanese Maples as much as I do, you can learn more about these amazing trees by joining the Facebook Group – Japanese Maples and Conifers.It is free to join – you just have to be a Facebook member. The contributors to the group have a wealth of experience and post many photos. No question is dumb – you will not be criticized for lack of knowledge, rather you will get a variety of opinions from all over the country and beyond. This is what I value the most – learning about variations of growth, leaf size and color in different sections of the USA and around the world. I often participate in the discussions.
