I have a tall early blooming pinkish lilac with creamy yellow center clematis, some of which have three layers of petals, some just one, with the center of the petals a lighter lilac color and the back of the petals have up to three red "veins" running from center to edge of petal. I have taken pictures, I'll see if it lets me post them. Any idea of varieties? It's almost like a Josephine, but not the powder puff looking stamen. It's relatively young.
