If you want a low-maintenance rose that has beautifully fragrant flowers that look real, and a growth habit that isn't gangly, then you might want to look to the species. The two that come to mind are:
Rosa canina is my personal favourite. Not too tall, nice and bushy, and the smell! I'm blessed to live in a climate where the bushes never stop blooming, and these things perfume my entire yard. I use them for rosewater for baking as well.
Rosa arkansania is another star (these are often sold as "wild roses") - amazing range of colour, double flowering cultivars starting to appear, crazy strong fragrance, and basically a weed so you just have to deadhead if you don't want hips, and prune for shape.
