I agree with Jean. Madame Driout has not been stellar as far as hardiness goes for me. Devoniensis and Mme Driout both suffered very badly during our late freeze, much more so than other teas. However, they each get some winter die back in normal winters whereas my other teas do not.

disease prone and a very gangly bush here.

However, the blooms are very pretty. I am going to try to prune mine back some and see what results I get.

I like the stripes, they aren't overwhelming at all.

Temperature was in the forties when I got up this morning. The closest weather station to Jim is in Hillsdale. Hillsdale recorded 42 degrees this morning. How do the tougher teas respond to forties in July?

Teas are fine with the 40's. They're hardier than many modern HT's, at least by a bit, but Zone 5 is entirely different.

Mme. Dréout is not a Tea, since it is a sport of the climbing HT, one beeatch from he11, if you ask me. Jim is asking for disappointment with that one. It loves the heat and will bloom all day long in the high 90's. Even in coastal Zone 9 it fails. What are the odds it will like Jim's garden? Close to zero. Just my opinion from struggling with it for 5 years. Rusts to death and dies back in the coolth.

The question is not whether or not 42 degrees will damage the rose. If a rose can't handle our summer lows, all hope is gone. The question is, will a climate that can see temperatures like that any day of the year affect the ability of the rose to "grow back after taking a beating". Winter lows in the -20F range deal quite a beating to roses that don't supercool well, and there is a great deal of growing back that would be required. Do teas do this better than other roses? In general I have found that expecting roses to grow back from winter damage and bloom acceptably isn't a very effective way to grow roses here.

I understand your point. Forty degrees in the summer isn't a problem. We have low temperatures in the mid to low 40's every summer. In fact, the lows were close to 42 this morning in both of my gardens. The Teas are stupendous with 40 degree lows in the summer.

My point is that Mme. Dréout is a difficult rose and it isn't a Tea. High day time temperatures are something The Madam loves. In coastal weather, we have both cool nights and cools days, often with summertime highs in the low to mid 60's. Madam does not care for that one little bit. Teas handle it fine, tho some will mildew.

I'm giving this rose a try, although I'm at the warmer margin of 6b, close to 7a. It's growing on a trellis on the south wall of the house and even so, had significant cane dieback this winter.

This rose is so beautiful but difficult, not robust.

I give up on the Madam.

But I was only partly serious in the first place.

Just posting about what seemed an unusual rose and one that ought to be talked about on this forum as opposed to some Austin. And z6 would be a stretch for me. I have a few but they are not even close to this one in terms of possible risk.
