Acer tataricum ssp. ginnala, or amur maple, is not recommended to plant, due to invasive tendencies. This species is non-native to Ontario and naturally occurs in northeastern Asia, specifically from easternmost Mongolia east to Korea and Japan, and north to the Russian Far East in the Amur River valley. It prefers a well-drained fertile soil and will produce a more vibrant fall colour when planted in more acidic soil. It is advisable to prune in the late spring (June), as cutting may cause sap to leak from the wounds. While this can impact the tree's appearance, it does not harm the tree. The amur maple is highly adaptable and hardy in the urban environment, making it easy to transplant, and isalso commonly found in the nursery trade. The Auditor General of Ontario has specifically flagged this tree species as a concern in the nursery trades ("Value-for-Money Audit � Management of Invasive Species," 2022) and as such should not be recommended for planting. For an alternative native to North America, consider Aesculus pavia, or Carpinus caroliniana.
