I live in South Georgia and am not an agricultural person. I have a single Chicago Peace Rose bush and it has grown from a 6in scraggly twig into a 4ft tall bush with multiple blooms every day. It is my favorite rose by far.

It's almost one year since I purchased my Chicago Peace rose from the local HD, in an impulse buy for beauty and fragrance. Soon (in about a week) it started to loose leaves, so I had to figure out why. Turned out that it had black spot. At that time, I had no idea what the criteria for buying a rose are, how a healthy/sick rose looks, etc. I battled the nasty stuff for almost two months until I really got it under control (can I say cure?). It went thru the whole hot and humid summer blooming, and continued to bloom till this day.
Now I can say that, among all roses that I have, it is definitely the healthiest, most resistant and strongest of all. I think I had one blind shot since I brought it back to health! To me, it means a lot!
It also rooted easily here, in Miami (one of my best friends wanted to experiment, though I told him that own-root in Florida is not good!), in the "cold" season (cutting from mid February).

When I lived in Las Vegas, NV, a neighbor was removing all the roses from his yard. Another neighbor and I were horrified so we took some. Of all, The Chicago Peace was so beautiful with large blooms and such a variety of color as the weather changed from hot to cool. When I moved, I was sad that I couldn't take it with me and after two years, I saw a bush in a local store and it's beauty is gracing my flower bed once more.

Our rose bed was augmented and transplanted last year, with varying success. Most of our roses did just fine. Our shining example of this is Chicago Peace. It's grown vigorously this season, and the blooms are enormous, not to mention beautiful.

This rose is a charmer. The soft colors, the fragrance, and the relative easy care made it one of my favorites. It is hardy in this growing zone. Barbc

This was one of the first roses I ever planted, and at the time I had no idea what I was doing. In the first couple of years it went without any pruning, feeding, and sometimes even watering and still bloomed beautifully. It will always be a favorite of mine.

This is one of the most photogenic roses there is. It's blooms are a carnival of colors and have a wonderful hybrid tea form.

Positive Colorado_Roseman On Dec 31, 2003, Colorado_Roseman from Loveland, CO (Zone 5a) wrote:

This rose has been a favorite for many years in my Grandmothers and Mothers rose beds. I have one in my rose beds now and she is a wonderful bloomer. The variations in each bloom help add to her beauty and mystery. Very winter hardy here in the Berthoud and Loveland, Colorado areas. No disease problems at all with this one.

This plant was lovely the first year, blooming july thru august, but did not make it through the winter (Jefferson County, Colorado - zone 4. Graft was 2 inches below soil level. It has surfaced this year as a lone cane, about 4 feet high, flowerless, wild. I'm going to wait and see if the parent plant can do anything interesting before I dig it up.
