Hello. I hope this is the right place to post this question.
I'm in Portland and am looking at planting a columnar form of Big Leaf Maple (Acer macrophyllum) called 'Seattle Sentinel in my yard. My question is whether anyone has reliable information on longer-term height and width. The the few online sources seem to provide mixed information and before I made any decisions I wanted to complete some additional due diligence.
Hoyt Arboretum has one and I checked it out (photo attached) but it seems to be a fairly new tree.
Anyone have any good information about this tree?
Thanks in advance.
Jason
