hiya great i find the best way is layering take a branch as low down the plant as you can and put it on the ground with something heavy on it to keep it down and it will root once rooted cut it from the parent plant and dig up and pot on toll big enough to plant out good luck

Heidib, thats a very good link, just looked.

Thanks Guys and Gals. speedy10 the plant is in a neighbours garden-someone I don't know, so your suggestion might be a bit tricky to achieve!. It does make a lot of sence (not sure if thats the right spelling, think it should be an s lol!) though. Thanks for the tip. I have tried this technique with Lavender before and it worked.

Heidib im going to the web site now thanks

Thanks again Heidib now I know.
