Where to start? Purple Lady Banks? Didn't think there was a purple....Maybe it is a rose whose name is Veilchenblau? If so, that one is really easy to propagate..I started a bunch of cuttings and have a number of plants.
I started my cuttings after the rose had bloomed..but you might try when the rose first wakes up, and after it blooms and see what happens.
Just me, I don't use any rooting hormone...I have been told it expires quickly and since so little is used at a time, I would never use it before it wasn't viable any more...
I have mailed a lot of cuttings and what has worked for me is remove the leaves toward the end of the cutting and wrap them in damp paper towels (not wet! just damp)
Then I put them in a baggie and mail them so they go fast.
