Unfortunately, Norway maple often escapes from these horticultural settings and moves quickly into adjacent native forests; often spreading without notice. Identifying a Norway Maple from a Sugar maple during the summer months can be difficult - the easiest way is to squeeze the juice out of a leaf's petiole and check if it is clear (sugar maple) or white (norway maple). The species are difficult to distinguish from one another based solely on the bark and leaves of the tree, and nearly impossible where seedlings are concerned. Norway Maples are a problem in Ottawa, London and Montreal and likely in communities between them.Anonymousnoreply@blogger.com
