I was shopping for plants and by accident stumbled upon a whole moon series of sedums: Harvest Moon, Blue Moon, Over The Moon, Moonglow, etc. Then I remembered that I have Solar Eclipse heucherella in my garden (other varieties are Solar Power and Solar Flare). I think you can see where I'm going with this! The bees love all of these plants, so when my bee landed on the Over The Moon sedum, he planted an i.d. tag in lieu of a flag so that the other bees could locate it, too. Such a helpful little bee!
