Any ideas what this plant is please?

At the weekend I saw this blue flowered, ground covering plant (sorry for poor photo, dh took it)
The globular blue flowers stand about 9” high above vivid green low foliage. I actually thought initially it was globe alliums growing through a green mat of ground covering plants but it’s actually all one plant.
There were also hardy orchids in another bed 😍 that I’m coveting!
Many thanks 🙏

Could be an allium caeruleum, possibly?

I thought Allium from the flower shape, didn’t know there was one that blue

@MereDintofPandiculation They're lovely, though. There's another allium obliquum that's a soft yellow that I love too.

I've had allium caeruleum and they are very blue, but the leaves are nothing like that. They're the typical allium leaves.

I don’t think any of the leaves in the picture belong to the plant in question. It’s growing up through foliage and its leaves are hidden

I’m starting to wonder if that’s what it was!
I’m going back there in mid July so I will have a closer look, difficult last time as at a wedding 😊
Thank you everyone, definitely putting allium caeruleum on my list 🙏

I also think allium caelruleum - the leaves pretty well die back before it flowers so they're probably dying under the other plants

A blue allium? Wonderful, I've definitely learned something tonight in the early hours when I can't sleep, worth being awake for.

It looks very like the garden I've adopted. Definitely allium. I had poppies pop through too 😀

Agapanthus was my first thought.

same

If you look closely at OP’s photo, the buds are bell shaped, more rounded at the base than Agapanthus. Focus isn’t good enough to see if the petals have the darker stripe of Agapanthus.

I think a sense of scale would help a lot to distinguish between allium caeruleum and agapanthus for ex. Allium caeruleum is really quite small. The flowers must be about an inch across, maximum. I've never seen an agapanthus anything like that small.

The flowers are completely spherical, about 3-4 cms across?

It's this.

It's definitely not a ceratostigma. The flower shape is completely different and the colour is too "true" blue, rather than purpley blue.

that's about the right size for allium caeruleum.

Fine to use an app to suggest possibilities but they can be completely wrong, as in this case, so you do need to double check.

The plant world has a major division, between dicotyledons, with two seed leaves, and monocotyledons with only one. OP’s plant is a monocotyledon, your app has identified it as a dicotyledon. Difficult to be more wrong!
