Wall speedwell (Veronica arvensis)

Observation - Wall speedwell (Veronica arvensis). Description: Another uninvited guest in the garden. I'm pretty sure that this is a Speedwell but less certain about which. I've plumped for Wall speedwell (Veronica arvensis) largely because of the blunt toothed leaves. Would probably be easier to identify in a month

Another uninvited guest in the garden. I'm pretty sure that this is a Speedwell but less certain about which. I've plumped for Wall speedwell (Veronica arvensis) largely because of the blunt toothed leaves. Would probably be easier to identify in a month's time when it's in flower.
