Do you know what this is.

Looks very much like Leycesteria formosa - Himalayan honey suckle or Pheasant berry.Nice plant will drip with dark purple flower heads that develop into similar colour berries summer through autumn.Will grow to 6' plus with similar spread can be cut hard back in early spring to contain.Evergreen.

I agree with bonkersbon on the id. This is well known for seeding so you probably have a neighbour growing it. It is not evergreen but the bare green stems look attractive in winter

I had three of these - they were evergreen in my garden (SW - so, mild-ish). I am afraid I hated them, they flopped all over the place, were hard work, and the berries made SUCH a mess. When we re-did the back garden I was pleased to get rid... but one has popped up on top of a wall!!!!! probably seeded there by a bird. It knows I can't get to it...

Also stayed green here but coast protects from harsh frost which Andrew may get .Sorry you dont like Spritz probably too unruly for you suits my jungle though.

I like them too - very elegant things me thinks :-)

Thanks for all your answers...im looking forward to see if it will flower.... its getting bigger every day.... i have had to cut it back a bit at the sides as it was taking over the garden.....
