Pennyroyal is cultivated for its use in culinary and pharma- 
ceutical preparations. It grows best on a tenacious soil, even a 
clay is more suitable than a light, silicious soil. It should be 
moderately fertile, free of stagnant moisture, and consequently 
on a dry subsoil, or well-drained. A wet soil makes the plant 
Inxuriant in summer, but insures decay in winter.
