HelpMeFind's future is in your hands - Please do not take this unique resource for granted.
Your support of HelpMeFind is urgently needed. HelpMeFind, like all websites, needs funding to survive. We have set a premium-membership yearly subscription amount as low as possible to make user-community funding viable.
We are grateful to the many members who have signed up so far, but the number of premium-membership members remains too small for us to sustain the current support and development level. If you value HelpMeFind and want to see it continue we need your support too.
Yearly membership is only $2.00 per month and adds a host of additional features, and numerous planned enhancements, to take full advantage of the power and convenience of HelpMeFind. Click here to start your premium membership..
We of course also welcome donations of any amount. Click here to make a donation. Donations of $24 or more receive a thank-you gift of a 1-year premium membership.
As far as we have come, we feel HelpMeFind is still in its infancy. With your support we have so much more to accomplish.

The rose Eugene Desgaches is classified as a China and Bourbon. Is it classified this way because the parentage is not known?

It is classified as both because the parentage is about even for both of them.

What would be its prognosis, along with VIVID, another Bourbon China, both evolved in warm climates from warm climate roses that DO especially well IN warm/hot climates in zone 5 NY?!! With careful protection? The answer seems obvious, but it never hurts to ask. Sometimes, one learns a lot that way. I have seen extraordinarily healthy plants of TYPHOO TEA at the Sugarhouse Rose Garden, Salt Lake City, c. 1984-86, very cold zone 5, totally neglected, high pH dry soil, absolutely magnificent.

I'll venture a very complicated "Probably Good."
I noticed when I moved from NJ, zone 6b to AZ zone 7b that roses which normally sailed through winter in zone 6 could sometimes fail here in zone 7 due to a western peculiarity in weather. I notice that we have a lot more periods of time in spring where days are in the sixties or seventies and nights are actually freezing. Or worse: we'll have stretches of weather in early March in the eighties and no nighttime freezing and then in April we'll get a night at 15F. Turns out this is really hard on roses, especially young ones. So to your point, Z5 Utah weather might test a rose more than Z5 New York weather.
I see that Eugene Desgasches is rated to zone 5b. I guess some bourbons inherited a good measure of hardiness from their damask lineage which might provide some protection not just from low temperatures but from the kind of yo-yo weather described above. If the hardiness rating is based on actual data, then I'd bet the prognosis for zone 5 would be good, provided it's grown on its own roots, mulched generously in fall, given a bit of protection from north winds, and given plenty of sun. As for Typhoo Tea, I'm guessing its rating of 7b is a default for hybrid tea roses, and that its heritage includes some cold-hardy roses that help bring it protection. If it grows in a western, mountainous zone 5, then there's a good bet it would survive eastern zone 5 winters.
