Veronicastrum virginicum 'Apollo' - 2020

That's great. I'm trying to grow plants attractive to bees, as much as I can.

Aleyna - bees are very attracted to blue flowers

Humm, I'll look for blue flowers that grow well in cold weather here. The native lupinus always have a lot of bees around. But not a single plant saved after the house building. The neighboors land has a lot of lupinus but I don't know how to save them. I'v tried the seeds unsuccesfully.
