Likely Blue Wave. And the colour shows the acidic soil there.

There are an awful lot of blue lacecap hydrangeas out there...... and most look pretty darn similar. Could just as easily be Blue Billows or Blaumeise. Or Bluebird.

But it’s most likely to be the one I named based on how long it’s been around (over 100 years) and how ubiquitous it is in the old gardens of Cornwall. They’re everywhere.

'Blue Wave' is a synonym of 'Mariesii Perfecta'.

I was too lazy to give both names. Typing at midnight over here.

Mariesii Perfecta/Blue Wave has been around for a long time and I will defer to any locals that this is what it is. It just seems strange (to me, anyway) that all blue lacecaps in the area are necessarily the same plant when there are multiple options that look virtually identical.

gardengal, hi

I didn't realise there were so many lacecaps, all of which would be blue. Acidic soil.

Knowing that the last time any major redesign of the estate, appears to have been in the 1860s, I was quite expecting this to have been a heritage spp. It was the done thing, at the time, to incorporate as may of the newly discovered/imported plants as possible. I know nothing of the history of Hydrangeas and their cultivars, but this, I would suspect, is a descendent of one planted during the 19th century

The estate was in the hands of the same family from mid-12th century until 1916.

Fof

the second and third pix are brilliant ...

do you use a real camera .. to accomplish that in full sun???

Yep. Don't have and certainly don't want one of these all dancing, all singing, "I'll do anything and everything for you"- type smart phones.

As an aside, but does anyone else see the Submit button, as Indsend. I seem to have the Danish button.

Out of curiosity, I rumbled though my favorite hydrangea monograph and counted up the blue in acidic soils lacecaps :-) 25 listed under H. macrophylla and 18 under H. serrata.

Now not all of these are readily found in commerce (more in private collections) and some will have colored or variegated foliage as well. And this is not a real recent publication so many new intros are missing. But still a heck of a lot of blue flowered lacecaps!!

Apparently Blue Wave was introduced in 1904.

If growing semi wild in the woods, rather than in the gardens near the house, I think it’s even less likely to be a newer variety. Hydrangeas are virtually naturalised in parts of Cornwall. Which garden was it thefof?

Houzz must think you’re in Denmark. The country button bottom left must have got bashed.

'Mariesii Perfecta' is a 'Mariesii' seedling raised by Lemoine ca. 1900. 'Mariesii' itself was introduced by Charles Maries from Japan in 1879. It produces a broad, flat head with jumbo ray florets.

If the plant asked about here is in fact a spontaneous seedling then technically it isn't any named cultivar maintained through cloning.
