Japanese Maple Tree Toxic?
Japanese maple trees are charming small maples with decorative leaves and astonishing and dramatic fall color. They fit nicely into a small garden. Gardeners and horticulturists prize these trees for their autumn colors and beautiful foliage. Japanese maples are typically small and perfect for small gardens or for growing in containers. Similar species include Acer duplicatoserratum, Acer japonicum (Downy Japanese maple), Acer pseudosieboldianum (Korean maple), Acer shirasawanum (Fullmoon maple), and Acer sieboldianum (Siebold's maple). The rumors that Japanese maple are toxic might come from the fact that a fungus that grows on red maple tree bark is toxic. None of these organizations list the Japanese maple or any of its similar species as toxic: ASPCA, Cat Fanciers Association (CFA), University of Illinois Veterinary Medicine Library and Cornell University’s Department of Animal Sciences. This has led some to consider all maple trees toxic; however, there have been no reports of Japanese maples being toxic to other animals or humans.
