Ken is there white strips in the green bark?

I have a few stripped Maples here and they don't get very big.
The bark on them are green with whites strips. The leaves on tem tend to be larger than reds and only have 3 lobes.

For what I understand is that they won't get large enough to tap if you even wanted to tap them. I pulled most of them out of the ground, just taking up sace where other trees can grow.
