I rent, so I got a limited space to work with. That said, I counted 12 bees buzzing my 3 anise hyssop plants (Two are 2 years old in the ground, 1 in a container from seed this year) and my (Monarda Citriodora) lemon bee balm! This is the most I have seen in my yard so far!
Walking conservation areas around here I’ve noticed they show extreme preference toward common milkweed and butterfly weed, and somewhat to nearby mountain mint. I have seen a few buzzing my salvia as well.
What other native species have you seen bees go crazy for?
Seems like absolutely everyone (bees, wasps, beetles) loves goldenrod when it’s in bloom later in the year here in the northern US.
