Lance, Thanks for the sharing this info!
It's always so good to learn from actual experience rather that just the concept!!
We have a mountain mint growing here too called Pycnanthemum incanum that really attracts many varieties of bees, hoverflies, wasps like a magnet! I have found that to be true of a few other natives here... when they are in bloom all the native insects are buzzing around!
We have had so much heat this summer that some of the mountain mint did not do too well. This patch found growing among the other natives in partial shade is thriving!
