Apricots in Z 4 or 5
I've been trying to find a couple of Apricot trees for sale nearby (Chicago area), but nobody has them but one store. The local independent nursery doesn't have them. The one I bought appears to have died, and the rest of the group still at the same store also look to have pretty much died before even being sold.
I can take the one I have back with no problem, but I'm wondering if apricots are not quite cold hardy enough for Zone 4-5? Is there a certain cultivar I should look for, or vendor I should contact? Comments welcome!
