How close to the actual color is the picture? I had Royal Velvet and lost it ( moles ). A deep rich purple grown mostly in the shade and `bout 8` tall. A favorite so of course.......
The data base has three pic`s only the middle plt pic looks dark enough to be the one I had. I have a plt now that is getting ready to bloom that also looks similar to yours, maybe
Just can't think of the name right now,
