The bees will forage hubam for sure. The question is will it grow well in your soil and climate and do you have enough to make any difference. I've never bought less than 50 lbs of clover seed at a time and usually not less than 250 lbs of clover seed at a time... In the last two weeks I bought 800 lbs of clover seed, some hubam, some white sweet, some yellow sweet, some white dutch, some alfalfa, some birdsfoot trefoil, some hairy vetch... it's hard to plant enough to make much difference...
