seen in a friend's garden - I really like it, and want one (so need to know when to take cuttings etc ). They have two - one's abougt 3ft high, and the other is rather overgrown/leggy at about 7ft high.
Leycestria - Himalayan honeysuckle.
Leycesteria formosa, himalayan honeysuckle. I've never tried cuttings but it self seeds well. If you look around your friends garden you might be lucky enough to find some babies
Leycesteria is easy to grow from seed, or you can take softwood cuttings in early summer. Quite cheap from the garden centre too...
