Backwards Beekeeper Stan sent a great link to this post on the City Bees blog that gives a bit of background about the First Family's organic garden and resident bees.
On Tuesday, March 24, the first known hive of bees at the White House arrived at their location on the South Lawn. You don't have to count on my crummy photo to see them: just stop by the fence on the Ellipse (south) side: two deeps and a medium of Maryland mixed breed bees, with known Russian and Caucasian genetics.
The White House beekeeper is Charlie Brandts, someone who has been a quiet beekeeper in this area for three years now. His reserve is probably why he asked me to do some of the talking about his idea to include bees in the White House Victory Garden project.
During the 2008 campaign, Michelle Obama emphasized healthy, local food, and since arriving here has tasked her family's personal chef, Sam Kass, with putting a garden in to supply fresh produce for the Executive Mansion and educational events for the community. Charlie realized that this was a chance to include bees, and to show their important role in putting one of every three bites on your plate. Charlie allocated (free of charge, people!) one of his own hives for the White House Victory Garden, and it will both provide hive products and an teaching opportunities.
