African blue basil. I get tons of bees on it 12 months of the year. In fact, in the spring when I want my trees pollinated, I cut it way back because the bees would rather attend to the blue basil than my fruit trees.
"The rule of no realm is mine. But all worthy things that are in peril as the world now stands, these are my care. And for my part, I shall not wholly fail in my task if anything that passes through this night can still grow fairer or bear fruit and flower again in days to come. For I too am a steward. Did you not know?" Gandolf
My 10 foot tall hibiscus (rose of sharon) is completely loaded with all kinds of bees right now! I am enjoying watching the bumblebees burrowing down into the flowers and getting covered in yellow pollen!
