There area few types of these dwarf columnar Norway Maple clones around. Perhaps the best known is the cultivar Acer platanoides 'Rezek' (of Ed Rezek fame).
The late Bill Janssen of Collectors Nursery was always on the lookout for these mutants too. Scouring tens of thousands of seedlings for these dwarf oddities. He & Diana had a planting of them in their display garden and many years ago shared a few scions with us. We lost a couple along the way but still have one of the red leaved selections & one of the green growing in the garden. Great plants so long as you are not in too much of a hurry ;^)..
After their hair cut!
