Will definately give the lupin cuttings a go this year Bunny as well as taking cuttings off the lovely Bowles mauve wallflowers that I got as small cheap plants but have grown into lovely shrubs and still flowering. Although they are growing I think it's too early (even for me) to take cuttings now.
The purple one had some lovely off shoots last year which I gave to a non gardening friend, regret that now as I think she might have killed it.
I'm on the look out for a white variety, did get some tiny ones last year but they soon disappeared and i'm not hopefull they will come back this year.
I do like them flowering rose and so do the bees, glad yours are doing well and the slugs haven't found them.
Clicked on your link Gardengirl, they look stunning
