Saw these at a nursery today, very interesting but only a little name
tag and no other info, the nursery guy just said that they came in the
other day and he knew nothing about them. I can not find any useful
information via google searches, other than conflicting reports on
it's hardiness (found sites saying zone 5, 6, and 7.)

Anyone know anything about this one?

This nursery had a ton of interesting plants and shrubs. It is only
about a twenty to thirty minute drive from my house but until today I
had no clue how to find it. They had a gorgeous Lion's Head Maple
there for $375.00, it had the weirdest shape to it, but I've bought
way too much this spring to even consider buying another expensive
tree.
