I have only ever seen them at Home Depot up here in the Twin Cities which does an excellent job of carrying plants that are marginally hardy, if at all.

Yes, I agree about Home Depot. We didn't find any Giant Thujas, but lots of things that wouldn't even grow here in Iowa. They said they do have them every so often. I'm needing more, so I'll keep my eye out. We ended up ordering from The Botony Shop in Joplin, MO. Not too bad a price considering shipping. Thanks for your contact.

Home Depot . . . which does an excellent job of carrying plants that are marginally hardy, if at all.

Especially true this year. I did see some Green Giants there a while ago.
