This rose lived in my garden for 3 1/2 years. I gave it a chance. Perhaps I'm one of the few who had a negative experience with this, but it did not give off much fragrance no matter how I adjusted the pH. Secondary, it defoliates at the drop of a hat. It struggled for the entire 3 1/2 years. It requires regular spraying and I'm not about to do that. Quite possibly is a good rose with regular spraying, but that's why I'm not one of it's fans. Shovel pruned.

J&P lists Julia Child as zone 5-10.

This rose had very poor black spot resistance without spray in my garden near Washington, DC. To its credit, it seemed content to photosynthesize with green stems alone, and persisted for several years that way until I couldn't stand to look at it anymore.

I'm probably among the few that dislike this rose.

I don't particularly like the habit, and it defoliates from BS greatly here in NW Oregon.

I prefer its descendent Sparkle n Shine. The scent is a lot nice, and the color is A+. BS isn't an issue for it here. It, however, can be a little more cold tender.

Or Sunsprite, which is the old stand by. It does its job and smells nice. It's more cold hardy than both. At least here.
