Yes, I confess it, I even have some Dead-Nettle growing in the bed next to the house. (Not much.) The bees aren't complaining. :)
They like Georgia blue speedwell too, which started blooming in January and will continue until the weather turns hot.
Carpenter bees make such good photographic subjects. They are not at all skittish, and their size makes them easier to photograph than some of the smaller, fast-moving bees.
