Tutsan or snowberry - plant ID

[SaffaQueen]

Hi, any ideas on what this shrub is? It’s popping up everywhere along the hedging/edges. Think its one of the above, very unsure however & hoping it’s not the dreaded knotweed!
Little black berries, which I don’t think the latter has.

Another photo to give idea of height.Red stems and new leaves are red underneath.

Is it a dogwood

Not a dogwood.

No idea what it is!

I thinks it's tutsan, a variety of St John's Wort, hypericum androsaemum. It is semi evergreen, has yellow flowers followed by berries that gradually turn from red to black. It's a native wild plant, the flowers attract bees and birds eat the seeds though not the fruits. It seeds itself around at the top of our drive against the neighbour's fence which I rather like.

I thought hypericum too.

Looks like a hypericum to me too. They can seed themselves all over.

I have a brilliant plant/shrub/tree identifier app on phone.

It agrees with @Halfhardy- it is a tutsan, species of st johns wort

from genus Hypericum so @Tambora and @WeAreTheHeroes* right as well!!

Frustrating when the same plant has several different names, isn't it?!

The leaves are far too big for snowberry, so Tutsan. If the black berries belong, that clinches it. There is a possibility it could be another Hypericum, H.calycinum, Rose of Sharon, tends to be taller and with much bigger flowers. Leaf shape totally wrong for japanese knotweed, which is a far more robust plant, and has alternate leaves, not leaves in opposite pairs.

I imagine OPs choice of ids came from a plant app. Plant apps are find for a starting point for further research, but they are simply pattern matching. They can get it stupendously wrong and have no awareness that they have done so.

Frustrating when the same plant has several different names, isn't it?! That's why they have a unique scientific name.

Thanks all - so sounds like I should keep it!

Only if you want it!
