Can anyone identify this tree in dd’s garden?

I've never seen it before, but the shiny leaves look like magnolia.
Hawthorn leaves are smaller and not shiny - we used to eat them.

Viburnum I think. Look it up.

Thanks, both. However it’s def. not a viburnum, I have one in the garden and there are more nearby so I know what that looks like.

It looks like a rhododendron flower. There are loads of different rhododendron plants.

Witzend, try comparing your photo with a picture of a dotted hawthorn. It looks very similar to me, it's a North American tree.

Posted too soon. This might help with your identification.

I was admiring some similar trees on my walk this morning, but sorry, I don't know what they are. I shall be interested in the answer.

It looks like my climbing Hydrangea but mine won’t flower for another few weeks yet.

I suggest you post on Gardener’s World website. They are wonderfully knowledgeable.
I would have hazarded a guess at a hydrangea as the leaves are similar.

Azalea family ?

Witzend PlantSnap suggests Prunus Virginiana en.m.wikipedia.org/wiki/Prunus_virginiana#/media/File%3APrunus_virginiana_flowers.jpg

I have to say my first thought looking at the leaves was that it was some sort of Prunus.

It’s definitely a vibe rum. There are loads of different varieties,I can’t remember which one.

Viburnum especially if the flowers are very fragrant.

It looks like a Wayfairing tree. Species of Viburnum

Great to see the answer. Thanks from me too.

Thank you all. Minimoon, that certainly looks like a possibility. It’s not a rhododendron or a climbing hydrangea (I’ve got one of those) - it’s def. a small tree rather than a shrub or shrubby-type of tree.

Some people get a scent of Lillies but others can’t stand the smell?

It may be a Sorbus eg Sorbus intermedia (not Sorbus aucuparia - Mountain Ash). Are the backs of the leaves downy?

It may not be this variety but I've sent the pic as a guide.

Or it may be a Cratageus, which includes Hawthorn. What's the bark like? Is it thorny or not?

DH (a botanist) and I (plant lover and gardener of 40+years) are pretty sure it's not a Viburnum, Hydrangea, Rhodedendron or Prunus virginiana.

Sorry shysal, we don't think it's Virburnum lantana. If you compare each individual flower to the OPs photo, you can see that hers show them to have rounded petals. V. lantana's individual flowers are very different.

We're almost 100% sure it's in the Roseace:

I'm unable to find reference to Cratageus punctata in Britain so it may be confined to N. America/Canada

Thanks everybody. The leaves are not deeply serrated like that pic of sorbus, Northernlass , they are very finely serrated. Don’t know about the backs of leaves - shall have to ask dd to send a shot.

Might it be this? Spiraea Vanhouttei

Picture might help!

I think it's a viburnum tinus. I have one.

Is it evergreen Witzend? I should've asked that in the first place!

Virburnum tinus is evergreen. Spirea vanhouttei is deciduous.
