Hi Dick, The Vine Maple is related to Acer palmatum in the series Palmata and is the only member of this series to occur outside of Asia. Apply what you know about Acer p. which also has big leaf and long internode, but are quite common.
I feel this tree is way understated and under-utilized. Some of the developed cultivars a very appealing.
As a matter of fact- I have recently brushed out three+ miles of mountain road and the main culprit was, you guessed it, Vine Maple. There are at least a dozen good sized clumpy clusters growing along the road side that need to be removed. I would consider these to be of premium stock for anyone interested. I will be digging as many as I can get out before the grader moves in.
As far as collecting goes I find you can pull them like weeds. Cut the big roots, get a prybar under it and pop it out of the ground. I don't do that, I'm just saying it's that easy, I use a shovel. I have one I'm growing that I found by the side of the road. It had been snatched out of the ground by an off-road quad and laid there for a week before I came along.
I have this thing about Vine Maple (can you tell?) and that is I want to create a scene with these trees the way they exist in nature. They are wispy and ethereal, seeming to defy gravity and just float above the forest floor.
I have a few experimental projects in the works here at the shop, but I'm not to the defining stages yet. I have cut alot of VM in the woods and seen the result of hard prunning and re-cutting repeatedly over time, such as roadside trees, and these trees are tough and hardy and reduce well if defoliated. Boy! Vine Maple, don't get me started.... Rick
