“Mountain” is a bit of a misnomer since the plant typically grows in the wild in dry woods, dry prairies and along roadsides.  All parts of the plant emit a strong aroma of mint when crushed.  Dried leaves can be used as a flavoring and in tea.  Attractive flowers.  Easy to grow.  Vigorous and sometimes aggressive grower.  Attracts birds, butterflies and bees.
