Margie .... Green Ice makes a magnificent tree rose because it is a weeper, but to my nose it is not that fragrant. It is one of the most trouble free roses I have grown in both in San Diego, where I grew it as a tree rose and up here where I am growing it in a large container.
It can be kept small or large because it doesn't mind a harder prune. In San Diego, it showed no mildew in a garden where many roses had that problem. I've never seen black spot in either location. It is somewhat drought tolerant and handles both the high temps of summer and the cold temps in winter.
Here's a photo taken at twilight of the rose I am growing in a container:
Another rose that is fragrant that makes an incredible tree rose because of it's weeping habit is Sweet Chariot. The rose in San Diego had a four foot head. It was always stunning.
The hard part is finding both roses sold as tree roses these days.
I couldn't find a photo of Sweet Chariot as a standard rose.
I could list several more, but not all of them are fragrant.
Smiles,
Lyn
