Identifying a plant

Could you post a picture?

They sound to me like lacecap hydrangeas.

Lacecap hydrangea?

X post!

They sound a bit like lace cap Hydrangeas, but they are unlikely to be in flower yet.

Great minds think alike (and fools seldom differ)

As soon as you ladies suggested that I realised I have one, I ran down the garden and found just the one flower, bit of a poor specimen but I think you ladies could be right..

I will sprint out in a mo and take a photo - in the rain!

Ah no- the decking is very wet - I will take one later. It does look a bit like the mophead hydrangea, but it is flatter, and white.

Luckygirl they do usually have lots more open flowers surrounding the unopened buds as I say that’s not a good specimen

Here are some pics- the close-ups will be very poor quality as I had to zoom in to avoid slipping over on the decking!

I think it looks like the oak-leaf Hydrangea - Hydrangea quercifolia.

Just looked at some pics of that and it is similar - but my flat circular blooms are not quite the same. The middle of the bloom has such tiny flowers that it looks as though there are none - then it has these white florets all round the rim.

The outer flowers are really just bracts, the real ones are the tiny ones in the centre plate.

I don't know - but what a lovely garden!!

Thanks Jalima - I am novice gardener and have worked very hard on it and feel quite pleased with the result.

I should get out and do a bit more in our garden.

And I have summerhouse

Your hard work is paying off Luckygirl

I'm not sure what it is, Luckygirl, because from your picture, the leaves don't look like the leaves on my mop head hydrangea and as shysal says, it's still a bit early for them to be in flower here. Whatever it is, though, it looks very pretty.

My climbing hydrangea looks a bit similar and is just starting to flower, but it is not a self-supporting shrub. The centre is greenish-white rather than brown though.

The leaves on yours look like an oakleaf hydrangea, as NantheWiser said.

I must admit, I've never heard of an oak leaf hydrangea before. ?

Yes Jalima the leaves are very distinctive on this species, unlike ordinary Hydrangeas. It is only just starting to flower, and the centre of the panicle will slowly develop into a drooping cone of flowers. It's also renowned for its Autumn colour.

I've found it!!!! It is Hydrangea arborescens Haas' Halo:
