My favorite native tree. Your presentation evokes what I see wandering the rivers while fly fishing.
I'm reworking my front yard to remind me of the banks of the Sol Duc river (my restorative place) on the Olympic Peninsula with a large (15') vine maple clump as a central focus. Unfortunately, it's not doing so great in it's second year. Can't figure out why - morning sun, soil chem is OK, etc. They grow on the riverbanks so I didn't think you could overwater one. The non-native river birches, however, are doing amazing...
I recently found several clumps at approximately 4,000' that are growing in a rocky seep that seem extractable. I'll try to collect next year. They look very similar to this but slightly larger trunks.
