It's most likely a Manitoba Maple (Acer negundo).

Ian, the species A. platanoides and their cultivars are border line hardy in the prairie provinces. If her tree self-seeded and her neighbours all have these trees, itÂs a Manitoba maple which are very common and very hardy in our zone.

Thank you both for your replies - you've been very helpful! Much appreciated.

Not sure it's a Manitoba maple (acer negundo) as that tree would likely grow more than a foot per year. The first few years it gets established and then takes off.

Not to add to the confusion, but is the entire tree greenish yellow? Maples on the prairies can be susceptible to iron chlorosis, lack of iron caused by clay soil, which might make the leaves more yellow than they normally would be.

Whatever it is, if it's a nice color and doesn't grow too fast, it sounds like a nice tree to keep around.

I have the exact same thing, methinks. Could it be just 'yellow maple' ? All I know, it has a much slower growth rate than the sugar maple. Grows like the red maple.
