Common Snowberry, Symphoricarpos would be my guess.

Spreads like hell, any bit you pull up from the root will grow, so not really necessary to take cuttings.

Agree - we spent weeks clearing it from our last garden.

Oh, not quite the reply I expected. So presumably it wouldn’t make a hedge then ? I need one quickly.

Yes it can make a lovely hedge and quite quickly, however if used for hedging then you will need a good mattock to grub out the suckers, it’s a simple task if you keep it in check by doing it annually, but a harduous one if you let it spread, that said it will give much interest with those lovely largish snowberrys through the depths of winter.

It is poisonous though the white berries aren't enticing and, if anyone is tempted, the extreme bitterness will deter consumption.

Thanks Julien, that’s just.what I wanted
