Does anyone know what type of tree this is? It looks like a maple, but the leaves stay a bright lime-green color. It also doesn't have any fruit, etc...

Looks like a sugar maple.

To be more precise, it looks like a chlorotic sugar maple. That sort of overall yellowish hue is often due to nitrogen deficiency.

So perhaps the results of a soil test could reveal a specific fertilizer to use?
Looked allright to me I thought it was the sunlight shining on it. :lol:

Someone else thought it may be a Norway Maple cultivar. Several other trees in the area, including one maple only a few feet away are all very green, thus leading me to believe that the nitrogen level is fine. Also, the leaves do not turn red, etc.., in the fall like sugar maples. I have add standard level fertiliser spikes on a regulalar basis. :? I have also added more photos, showing the bark.

Yeah, that could be a Norway, seeing the bark. To confirm, pluck off a leaf. If it's a Norway maple, the sap in the petiole (leaf stalk) will be milky white. If it's a sugar, the sap will be clear.

I've never seen a maple cultivar with that color, but I could certainly be wrong. I must admit, it does look pretty healthy other than that.

Yes, the bark looks like a Norway Maple:

- Thanks, again. I did the petiole sap test and sure enough there's white sap. So it seems that it's confirmed. The next step is to try to figure out which Norway Maple cultivar it is. I found these two websites helpful.

Best regards,
