Unfortunately, I do not think this will work. Bees, to the best of my knowledge (and there's not much there, so take this with a grain of salt) are not actually attracted to the plant itself, but the sap from the plant's root. Again, I could be wrong.
Its not even the sap I think but the distilled oil from the sap.
Lemongrass itself, makes a great part of a salad or side dish or in a soup. I'll actually be offering it at farmer's market's this year if I can get it to grow in large enough quantities.
Supposedly citronella comes from Lemongrass. Not to sure how that works out since its a repellant not an attractant.
Who knows.
