Overview

Mentha pulegium is a perennial species from the Lamiaceae family. It is commonly known by the names Pennyroyal or Pennyrile, amongst other names. Pennyroyal has a low spreading habit and can be used as a ground cover. Though it is somewhat sparse in the winter and can be invaded by the more aggressive weeds. Crushed Pennyroyal leaves emit a very strong aroma similar to spearmint. Small purple blooms are produced on vertical inflorescences in whorls during the summer. The fresh or dried plant will repel fleas, ants, moths and rodents.
