  • Question

    My sister who lives in Cary, Maine, gave me this small mountain ash that she dug up near her home, which is in a large wooded area in Northern, Maine. She believes it’s a native mountain ash, but after doing some research I’m not so sure. Can you please help me determine if this is Showy mountain ash or European mountain ash? Pics attached. Thank you. Susan H.

    Answer

    Dear Susan, good morning. I can't tell you for certain because I need to see the branchlets and winter buds. However, the general hairiness of the leaves and petioles suggest this is Sorbus aucuparia (European mountain-ash). If you find that the branchlets and winter buds are very hairy, you can confirm the identification as the non-native. Best wishes.
