My wife has a couple of sedum plants in the front yard, one plant on each side of the front door. The flowers are now starting to open, and the bees seem to love it (both honey bees and bumble bees). In fact, I have to be careful when I open the glass door not to sweep bees into the house with the wind!
Here are some pictures. You may have to zoom to see the bees, as they blend in with the sedum flowers.
