I just received a Abies koreana 'Horstmann's Silberlocke' fir. I was told that it grows to a height of 10 feet. However, after a brief internet search it seems the tree grows to a height of 10-30 feet. I'd like to plant it in my front garden which faces north-west (Zone 6), but I don't want a tree that is 30 feet in the spot that I'm considering. Apparently it's quite a slow growing tree.
When established propagations of this one tend to assume habit of typical species. Leaves may even begin to uncurl with time.
