I received our Marie Daly as a transplant last spring, even though we had a much warmer than normal winter in 2011, Marie Daly lost only a few leaves, and even in the warmest part of the winter-when it was in the 80F range, we had a bloom or two.
The rose is very healthy even in hot humid conditions, or cool humid conditions, it did show a slight bit of blackspot, but I just I just hosed the plant off, and then drier sunnier weather conditons took care of the rest. It does have a few prickles underneath some of the leaves, but I would say it is thornless. In cooler weather the blooms look more like miniature hybrid tea blooms, wonderful fragrance, it has a nice tidy habit, and looks good by the kitchen door.
This rose lost about 2/3 of it's canes in the Winter of 2013, "the coldest ever", really a zone 4b. We have had very little snow, and lots of cold wind.

Grntrz5: My Marie Daly died one winter .. it was in wet clay. Since Marie Daly is an Earth Kind-drought tolerant rose, I suspect it prefers loamier soil. I'm ordering Marie Daly again, and would like to know what's the best soil to ensure zone 5a winter survival. Is your soil sandy, loamy, or clay? Thank you.
Previous years I private-messaged a zone 5b person, she also reported Marie Daly dying through her winter. And a friend of my daughter also said her Marie Pavie survived our zone 5a winter, but Mary Daly died through our -20 F winter.

This is a species rose I am trying to get to know. How long have you grown this rose, and how does it behave in your garden?
Thanks,
Vince

Vince, I have had this about 5 years, I received it from Cliff Orent when he was moving and needed to reduce the numbers of roses he had. I'm thinking that it might be better in a place that has cooler mountain temperatures. Check out the comments section under that rose; there are tabs at the top of each plant entry.

Rose Listing Omission
Rosa obtusiuscula Rydb., nom. inq. Appalachian Valley rose
Rosa obtusiuscula Rydb. the Appalachian Valley rose, is mapped only in Tennessee in the USDA plant database. There is no wetland status given for this rose, but looking at area images, this thornless rose looks to be an OBL to FAC type plant. It was collected August 25, 1897 along the French Broad River, between Paint Rock and the town of Del Rio in Cocke Co., Tenn It is thought to be it's only location. (New York Botanical Garden specimen),

I would appreciate it if an American Administrator could add this one please.

Thank you Patricia; maybe others can re-evaluate this rose. After I posted this I started to think, maybe it is another name for a rose that can be found elsewhere, or is an escaped hybrid. The online images are fairly clear for someone to look at it.

Died over winter of 2013, basically a zone 4b this time. It wasn't in strong condition before that; NOT a good rose for the Great Plains. None of the Tom Carruth have survived here.

Weeks Roses generally breed for Zones 6-10, and there are a select few that can survive lower than 6, like Cape Diamond.
