My first thought was a Laurel? but the length made me wonder if its a Rhododendron? but perhaps not lol. Someone will tell us soon.

Looks like Rhododendron to me. If unlucky it is Rhododendron ponticum if lucky then one of the smaller none invasive ones.

Thanks for the answers.

Based on further reading I hope it isn't the Rhododendron ponticum - seems to have caused a lot of damage to our native plantlife.

It's not flowered since it sprung up and growth is quite slow, so I'll keep an eye on it.

I don't think that it is a rhododendron, the leaves don't look at all right and they are very difficult plants to propagate from seed.

Looks like a Rhoddie to me:

Have seen seed heads on Rhoddies not far where you live Bulba at Broddies farm shop!

Plenty of seed heads, Kildermorie, but still difficult to get them to germinate. (Brodie CountryFare is a mile from where we live).
I have just been looking at a R. pontica and am prepared to say that I might be wrong (!) in my earlier post. The leaves on a mature stem are almost in a whorle round the stem but I now see that the leaves on the new growth are individually spaced out as in Andi's picture. Obviously, I have never looked at them closely enough before, sorry.
And, of course it depends if Andi has any ponticum growing in the vicinity of his garden.

I've not seen any ponticum nearby either wild or in gardens. I'll keep you posted as to growth and any flowering.

Thanks all.
