Little did we know when a Norway Maple seedling began to grow into a gigantic tree. It’s a beauty, but has been hollowed out three times at considerable cost. We also have two more Norways in the front of our house. They were planted by the city, and have also been cut back. I spend half the summer sweeping up seedlings.North America’s Sugar Maple is another story.  It has pride of place on Canada’s bank notes, and the Canadian flag. The Sugar Maple has three wide lobes (or main points), each with a few irregular wavy teeth, plus two one-point lobes near the stem. The Norway Maple’s leaves have seven lobes.
