I think this is Lilac Ivy-leaved Speedwell, found in a semi-shaded woodland margin, where all of the flowers seemed to be very light
An Ivy-leaved Speedwell flower, which I found in an area that receives more sun. Perhaps it might be Blue Ivy-leaved Speedwell, although there was an area that seemed to be Lilac Ivy-leaved Speedwell relatively close
Some Ivy-leaved Speedwell plants in an area that receives more sunlight had a few flowers that seemed blue. My old guide book says that Blue Ivy-leaved Speedwell has more sharply toothed leaves and bright blue flowers, compared to Lilac Ivy-leaved Speedwell - but there's a photograph of a blue flower as an example of Lilac Ivy-leaved Speedwell in the online Plant Atlas 2020 - so I've been having trouble trying to understand the differences. Perhaps this is all Lilac Ivy-leaved Speedwell?

Out of curiosity, does anyone know about Ivy-leaved Speedwell subspecies? #WildflowerID I've been finding some blue flowers together with lilac flowers, but perhaps it's all variations of Lilac Ivy-leaved Speedwell rather than Blue Ivy-leaved Speedwell?
