I visit a local rose garden several times throughout the year and this rose never failed to impress me with it's beautiful rich purple blooms as well as the healthy looking foliage, so much so that I ended up planting two side by side to maximize on that purple color. One of my favorite roses, wonderful vigor and deep green healthy leaves.

A poor, weak grower that seems to be suseptible to blackspot and doesn't bloom often. I'll have to search for something else if I want a purple rose. :=(

One of the many new "Blue" roses...actually a reddish purple that ages to a nice grape juice purple. The white stripes and hints here and there give the blooms character, and the color is a show-stopper!! Not a lot of fragrance, but what it does have is nice. The foliage is fairly disease resistant, and the bush is well covered. An over-all nice rose.
