I've grown this in Eastern Ontario (zone 4 w/hot summers) and central Alaska (zone 3, short cool summers). In Ontario it became very tall, full & suckered freely. Not much repeat. In light shade in Alaska, the very young plants have reached 3'. Scent varies.
Probably the best hybrid for cold climates.

Of all the roses I’ve tried and heartbreak I’ve endured as a Zone 5b gardener, finally—a winter hardy rose that doesn’t disappoint! Despite what it says here, Therese DOES have thorns on the bottom of her canes, but I find they help protect her against rabbits. And ‘yes’ Japanese beetles will find her but not as devastated as the lighter-colored roses. I’m a Master Gardener and can say that if you want a rose that performs, that endures, that grows like a beast and even accepts bad pruning from errant lawnmowers (sigh!) give her a try. She doesn’t need a lot of babying but DOES need to have her fast-growing canes secured horizontally or else all you’ll get it a tall plant with flowers on the top. But, even THAT growth habit gets compliments!

I love my Therese Bugnet. She is own root with a fountain shape, beautiful red canes that brighten the garden in winter, and very disease resistant. I nearly killed her when I cut back Mimosa sprouts next to her and applied brush killer to the stumps. The roots must have transfered the poison to the rose roots next to it.(The Mimosa is gone!) I have stopped using that method to kill unwanted plants. Therese nearly died , but young sprouts came up and after two years is starting to look healthy. The Japanese Beetles love her blooms, but she just keeps setting buds.

This is a lovely old fashioned rose. Varries with stripped colors , few thorns. I know it will get bigger and have more abundant roses as the years go past. I LOVE the old roses.
