I have never seen an Ivy-leaved Speedwell with flowers this deep blue. Are there any other species with blue anthers?
Just spotted this post so I looked through some of my Veronica images.
I appear to have many Veronica persica and filiformis images with blue anthers.
Stace p. 587 gives
3 Calyx-lobes cordate at the base 15 V. hederifolia
4 Calyx-lobes cuneate to rounded at the base ...... 23 V. persica
As mentioned above, no ivy-leaved Veronica has such a flower color. Almost certainly Veronica persica
This one does have flowers this deep blue, contrary to statements above. V. persica is paler.
