Lots of them growing at the base of a gappy hedge.
No interactions present.
Strange location for non-native bluebells as the hedge is in rural farmland 1km from the nearest village.
The only way to be sure is to see the plants in flower. I believe non-natives tend to have broader leaves, but in a non-urban location it's far more likely these are natives.
