Snowberry?

Well it certainly isn't mistletoe.

It is Symphoricarpos (snowberry). It is a suckering shrub so unless you want it to spread you will need to cut off any suckers which appear. Have a look at thepoisongarden website. It is listed there but does not seem to be attractive to humans.

Terrible, terrible thug. It has taken 3 years of weed killer on every leaf as it appears and pouring into the cut stems to get rid of it (we hope) from the roadside verge outside our property from whence it was suckering into the garden and out under the tarmac!

Gosh Owdb. that is some thug!

We got rid of ours,when I was told the berries were poisonous,as we had a lot of children pass on the way to and from school..

We moved to a house that had a lot in the front garden. when we finally got it all out we discovered there was a path down by the fence! I wouldn't have it again.

Used to have it in family garden where I grew up. Never got out of hand because my father would cut it down to the ground each spring - after the birds had finished off the berries.

Good pheasant cover (which is how it came to be naturalised in so many places). I.e., a thug!
