Maybe you've seen this along the trail, or on the roadside.  It looks like it's been dusted with baby powder.  It is Hoary Mountain Mint, Pycnanthemum incanum.  That's a mouthful!  We just call it mountain mint.  

 

Mints are distinguished by their square stems, and opposite leaves.   They also display compact bunched flowers atop their leaves.  Enlarge the picture and you can see the bunches of lavender flowers.

 

Be sure to notice it;  and if you're up close, crush the flowers and leaves, and smell it.  It has a fresh, clean mint fragrance.  Delightful!

 

I hope you see some mountain mint in your travels.   

 

 

HAPPY GARDENING!!!
