I don't really know why, but as soon as I saw the picture, wattle (Acacia) sprang to mind - but I've no idea if one variety has bright orange berries like this...
What colour are the flowers, does it have thorns, and is it deciduous? I'm also wondering about one of the buckthorns, but the way the berries are arranged isn't right, much more wattle like really.

I was thinking Sea Buckthorn too Bamboo. Have some in my mixed hedge. The leaves look too green, rather than grey

Yes, I thought sea buckthorn but there is something not right about it somehow...The leaves are a fair bit greyer than the photo, it is evergreen I will try to get better diagnostic photos. That means leaving the dog at home while I nip up the road for my morning paper.

I have sea buckthorn and the leaves are a lot greyer - and shorter.

This has a sort of weeping habit as well.

not buckthorn for certain. otherwise no idea. sorry.

When I say "weeping" it is more a casual flop, like a new romantic fringe.

LOL! Trying to think of a new romantic shrub with orange berries - they just don't go together somehow.

The leaves are 10 cm long.

I think it is Buckthorn..The male plant is next to it...Still just as odd though. But they are growing under the canopy of other Trees.

Could it be Buckthorn ... variety Rhamnus frangula ... ovate long green leaves with orange-red berries??? Berries will turn purple-black during the winter. If so, it is british deciduous, does well in any soil, in sun or partial shade. According to my book, after 5 years will reach 2m but ultimately 6m.

No... definitely not Rhamnus frangula.

I was wondering about Hippophae salicifolia, but I think yours has much longer leaves...

I could not find any thorns on it or the male plant next to it. The leaves are much longer than any other Buckthorn I have seen, although I said it was evergreen (i can never recall it having no leaves) it must be deciduous. The seeds are little black piplike things. I have stuck those cuttings I took in a pot, treated them as soft wood cuttings. Hopefully they will take and the new plant may give us a better idea.

i think the growing conditions may be why they are odd.

Well, Buckthorn isn't thornless, is it, so do you think its one of those?

Can't think of anything else...I will look for the flowers in spring as well.

Hippophae salicifolia ... alias willow-leaved sea-buckthorn

It should be...but it is very odd.

The berries are not poisonous in small quantities, very tangy.

I did test them properly.. skin test , lip test, cheek test and tongue test. I ate one. Very nice it was as well.

But I will wait to see the flower.
