My entire back yard is carpeted by Lamium, and the bees do indeed work it throughout the warm months. Close examination of the pale purple flowers (my grandmother called them bunny heads - look and you'll see why) reveals that the pollen is bright red. I don't think this plant is a major pollen source, but I can find a few cells of red pollen among the more prevalent dandelion in my observation hive right now. The flowers are small but deeply cupped, and the bees have to thrust their heads right down in during foraging. Several times I have been sitting in the backyard enjoying a beverage, and a bee with an intense, bright red spot between the eyes has happened by. It's quite a distinct and unusual looking pattern. After following some of these bees, I discovered they were working the Lamium. On the subject of "kill on sight" weeds, here are some disturbing factoids from the American Lawn Institute: In the U.S., lawns occupy more land than any single crop, including wheat, corn or tobacco. Homeowners use 10 times more chemical pesticides per acre than farmers do. Of 34 major pesticides commonly used on lawns, 32 have not been tested for long-term effects on humans and the environment. Sub-urban beekeepers, don't think pesticide hive kills are only a problem in agricultural areas. Personally, I think keeping grass lawns (and mowing) is insane. Fortunately for me, plenty of more interesting groundcovers do better in my coastal NC area than bluegrass, including Lamium. They are prettier, smell nice, and provide continuous summer forage for my bees. Rick Bodishbaugh
