Virginia Mountain Mint is quite common in Virginia. It normally blooms between July and September. It has this long bloom season because it blooms from the out inward. The flower does this so it can be pollinated for longer then it would be if all the flowers bloomed at once. It does not seem like there are any non-native lookalikes for Virginia Mountain Mint so there's nothing to worry about! The ideal planting conditions for the mint are in direct sunlit in moist soil but it can survive in part shade and in clay. Historically the plant has been used for treating fevers and mild colds. It is also used for its nice minty aroma.
