Mountain Mints, #1 for pollinators in Penn State Study

Short-toothed Mountain Mint, Pycnanthemum muticum

If you want continuous buzzing of pollinators in your garden, this is a plant to grow.  There are multiple species of mountain mint -- all native to North America.  Two which grow well here are P. muticum and P. virginicum.  The flowers are not showy by human standards but they apparently are for pollinators.  They prefer sun but in my garden thrive in part shade.  I've referenced a Penn State study below.  Their Center for Pollinator Research has lots of great information and links of interest to us in the mid-Atlantic region.
