For a list of plants that bumble bees like search for bumble bee conservatioN (can't remember the exact name of the web site).
As someone has already said, the key is getting something in flower all year (crocus early on through to asters later perhaps).
Golden rod - now the rain has stopped I counted approximately 200 insects - mainly honey bees - at one time this afternoon on a patch of Golden rod approx 3 x 1 feet. Not, perhaps, the prettiest plant going but pretty much maintenance free and good at tbhis time of year.
Also attracting the bees today in my garden is buddleia, majoram, fennel and some of the smaller (very invasive) sunflowers which are just starting to open.
