What is the height of the plant in first pix? If 8-28" is Veronica spicata. If 36-48", it's Veronicastrum, possibly virginianum.
I happen to have both. My favorite V. spicata is the 'Sight Seeing Series' (blue, pink or white) at 28', the tallest of all the Veronicas, great for the vase. If consistently deadheaded will bloom from late spring to frost... Kathy
Pix-s is the 28"^x30"> blue, V.s. Sight Seeing Blue
