I planted a Madame Hardy in 2004 where I live just outside of Edmonton, Alberta, Canada. We are in Zone 3 (USDA Zone 4) and it has survived every winter since. It's only drawback is the fact that it does not rebloom, but I would highly recommend it for its intense fragrance.
Surprisingly charming. I planted this because gardeners I admired such as Tasha Tudor planted it. I had never seen the rose other than in a picture. It's sooo charming. I purchased it from Heirloom Roses and I'm very happy with it. Photos can't capture the lovely shape of the bloom and wonderful scent.

Exquisite in my zone! I purchased mine from Sam Kadeem. On the north side of my garden this wonderful rose was in bloom for some six weeks. I allowed the stems, which at year three are over six feet tall, to bend and it increased the flower power while giving it a lovely shape. The buds are covered with beautifully formed sepals. The foliage is extremely resistent to blackspot and mildew. It requires a minimum of care. The scent is wonderful. I would recommend putting it in at least partial shade to bring out the splendid visual effect of its white flowers. This is the rose that changed my mind aboiut once bloomers. Thorniness I would describe as moderate. Recommended without reservation.
This is another antique rose I've added to the garden over the years. And like so many others in this class it only blooms once, usually in late May or early June. It is nicely fragrant, and on calm days the aroma from the flowers can be noticed in the surrounding garden. It's blooms are pure white with a small green center. As the flowers age there is a blush of pink which can be seen in the petals. It is a very robust, hardy shrub with very little care, except for removal of dead wood and regular fertilizing.
This plant has been said to grow in the following regions:
Lemoore, California Denver, Colorado Gages Lake, Illinois Macy, Indiana Massena, New York Van Etten, New York Marion, North Carolina New Boston, Ohio Linden, Virginia Chelan, Washington
