Plant with many small pinkish white flower

Hi.

This plant grow to 50-80cm high. It looks like a Veronica longifolia 'Alba', but I think it's not?



The bumblebees loves it

Thanks.

 

It's hard to tell without the foliage, but it could be Culvers Root
Veronicastrum virginicum (Culver's root)

 

Yes, that's the one. Next time I will remember to take some pictures of the foliage. I was so busy to follow the bumblebees

Thanks for the help!
