I have Pink Peace, one OR and one grafted. It will die back to the ground every winter, winds up about 3' tall or so, maybe 2 -3' wide. Repeats pretty well, no disease issues, big very pink blooms. If it died I would get it again. I have Chicago Peace, it's from a body bag and probably in too much shade, does about the same as PP, but fewer blooms, I should probably move it. Sorry those are the only 2 from your list!

I have or have grown all the ones on your list, and by far the easiest and most rewarding one is Earth Song. It's trouble free, disease resistant, blooms all summer, and has at least some surviving cane most winters. The blooms are loosely double hot pink and it can make an impressive mound at about 5' by 4' if happy.

All of the "Peace" varieties are variably tender for me even in a protected area, so I'm impressed that Dingo has overwintered two Pink Peace plants. At least 3 tries each for Pink Peace and Peace have failed, and Chicago Peace seems to be failing its second try. Same for Colorific - three tries in protected areas and it doesn't survive well. Star of the Nile died after two tries, and Gentle Giant only once, but it was in my protected spot.

Among the "Easy" series, Livin' Easy is a better hardy rose than Easy Does it that can be variably hardy. Livin Easy puts out orange loosely double blooms and tops out a little over knee height for me, probably more if it had surviving cane. It's relatively trouble free.

Dick Clark and Dream Come True are fabulous blooms of more traditional "rose" looking hybrid tea blossoms, both with dark pink edges on the blooms. I love the zowie pow high contrast of Dream Come True especially, and it's about 4-5' tall in a very narrow bush, and blooms a couple of spectacular blooms a year. Not exactly bushy, but a nice accent. It only survives in my protected zone 6 spot though, so it's probably marginally hardy in a regular zone 5 spot. Dick Clark is in a regular zone 5 spot and is about 6 years old, but barely knee high. He puts out a few blooms a year and has come back every year, but I'm sure he'd be taller and a better bloomer in a warmer spot.

Winnepeg Parks is a Canadian rose and should have no trouble with your winters and it would like Colorado. It isn't a very prolific rebloomer, and the one I planted last year in a less than ideal spot didn't come back. I suspect it will do fine in a normal spot. It has dark pink loose semidouble blooms, and it probably would take a couple of years before it bloomed much past the first spring flush.

So my recommendation is Earth Song definitely, Winnepeg Parks probably but put it in a less prominent spot, Livin' Easy if you like orange, and Dick Clark and/or Dream Come True to push your zone limits a little and go for pizzazz. As you can tell from Dingo's response though, there's a lot of difference among zone 5 gardeners and you may need to see what does well for you by trial and error. Don't be afraid to experiment! Just be sure to bury the graft (the knobby bit where the canes start growing) at least 2 inches below the soil so that it protects the main growing part from the winter. Otherwise, the rose you want may die and you're left with the dark red rootstock "Dr. Huey" that's mostly a pain in the neck.

Thanks so much for your comments. If I may ask, since most of these look like they could be iffy, what are your best performing/favorite roses?

Dick clark - has survived for me. It's vigorous & blooms well here.

Winnipeg Parks - will make it through winter. It blooms ok, but it isn't a wow kind of rose.

I don't have any of the other ones listed.

I really like david austin roses, many are rated for zone 5. Some for zone 4. I'm willing to try any rose that strikes my fancy. If it doesn't make it through winter, I'll just try something else.
