Sean, you mentioned planting buttercups. We have that species that grows like the wildfire out here in our wet Lower Mainland area. I try to eradicate this as much as possible because it overtakes everything. I pull it out continuously. We have so much other stuff that is good for the bees that I can't be bothered to let the buttercup take huge hold. I actually did not realize that there was any benefit to this noxious weed though. I have always observed the buttercup to see if any beneficials are ever using it for forage, never see any insect of any sort on it. Maybe your buttercup is different than ours. I understand there are about 500 species, though. LOL. Great day. Cindi
