Hi Neal,
The two red ones are classed like the other three as biennial,..however its the reds that have come back every year with no loss of blooms or scent,..they have a beautiful strong scent,..so far i have only cropped them back each year,..as for the others they will die back and become leggy with hardly many blooms so those i have to take cuttings from and re start but i take the cuttings at the end of summer so they are mature come April,..yes i agree cuttings are easier than seeds where these are concerned.
You may think it odd but i was thinking of you today,..you mentioned in your previous post that the Wallflower in the tall container was gorgeous,..today i noticed the container blooms are a lighter color than those against the wall,..i never noticed this before and kept checking,..it wasn't the light lol.
