Dandelions....they flower before a lot of others and they are always present but not aggressive....in my area where late frosts can knock out a lot of natives, the dandelions are always buzzing with activity!
Thistles....always there....full of bees, butterflies and flies.
Mountain mint....gets a later start but this genus, hands or wings down, gets the most visitors! It is busier than the goldenrod!
Dogbane is another top choice among pollinators...
Good thing about all these? Deer don't touch 'em
