BW is a hit or miss with bees from yr to year. Some, they'll work it well, other years not at all. But it is a delicious honey i agree. As a cover crop it is choking weeds very well as it grows quick; it may smother your yellow clover. As a weed itself - true, it re-seed easily and regrow and regrow - it is very easy to take care of, hoe so easily i wish i had only that as weeds!!! ;)
