Can anyone identify this plant? My backyard is full of it, along with henbit. The bees much prefer these little blue and white flowers to the henbit. I had to be careful walking in it to take the pictures, worrying about stepping on a bee they were so thick on it. And I guess they were gathering nectar because I didn't see any pollen sacks being filled. The flower is very small and grows right above the ground, probably not more that 1" high.
