Morden Sunrise is a tough plant.
It has spent the last two winters in the unheated garage.

Is it eventually going into the ground? I like the curvey petals; do they stay as the rose opens more fully?

It will go in the ground when I clear the quack grass in its spot!
The curvy petals do not stay---they are there just as it opens.

Yea, Morden Sunrise is reported to be a zone 3 rose. One of the most popular ones here in my area. See them lots everywhere.. which is why I don't have one.

That's one of my favorite roses because it handles both the cold winter winds (unprotected!) and the heat of summer.
