Kathy, the linden trees grow in our big city really well, (Vancouver) and I know that they also grow here, I have heard a beekeeper telling me that I should get some Linden trees for the bees. I do not know what zone I live in, I should know that, but I have never bothered. All I know is that we get lots of rain, can get freezing temperatures, snow, yep, Kathy, I think that it is pretty much like yours too. I am going to check out what zone I live in.....hold on...... OK, I went to this site, it looks like I am in Zone 8b maybe 8a.
Kathy you say you are in Zone 8-9, I see no reason why the Linden won't grow in your area, that does not make sense. I wonder if the species of Linden that has been talked about is a more tender one. I don't know much about Linden, but I imagine there are many cultivars of this species. Check it out. Have a most wonderfully great day, Cindi
This is the site for the map that I went to, but it is for Canada:http://nlwis-snite1.agr.gc.ca/plant67/index.phtml
