The Bees are a Buzzin' in My Herb Garden

They especially like these plants now. You can hear the lamb's ear  plant (front, next to what's left of the irises) as you walk  by it. And the bees are also all over the tall butterfly bush in the back and the sage plants on either side of it.

I'm not sure exactly what kind of sage is on the left side of the tall butterfly bush. I think its Mexican Sage, but I'm not sure. If anyone knows, please leave me a comment. Here's a close-up:
You can see that the flowers are grouped in little balls the length of the stem. I wish I had  written down the name when I planted it. Maybe I did and will find it. What amazes me is how much it has grown in two or three years from the four-inch pot transplant that went into the ground here. It's at least six feet in diameter, and that's after a brutal pruning last fall. It's almost completely covering the new white butterfly bush I put in last fall.
