Leaf cutter bees are very cute. I love seeing them too, and other native bees.
All great choices, Urban Wild!
I agree with herbs being really good pollinator magnets!
Hollys are one of those flowers that I've tried growing without success so far. But, I never give up.
Black-eyed Susan's are one of my favorites! They attract all kinds of pollinators and other beneficial bugs. I can always find something going on in B-E Susan patch!
She also attracts some not-so-beneficial insects. But, it's all good in the scheme of things...
