I have hardy roses as well; the hybrid teas are just for variety and in case I ever want to enter the rose show, although they never seem to be blooming at that time.
The new hardy rose this year is Prairie Snowdrift. I just put it in the ground this weekend.
Zone 4 roses are sometimes able to survive if covered so I also put them in the ground. I might try again at some time, but my space is very limited and I prefer to put plants in the ground that I know are going to survive. The others go in pots. I try to avoid paying more than $5 for a hybrid tea.
Thanks for the book suggestions. Since we're on the subject, I might as well give the Calgary Rose Society a plug – their book has gone into its second printing and is available on their website.
