Horticultural Description
Pennyroyal has shiny green leaves and the mint menthol scent, and is very hard and low growing, such that it can even be walked on. Although it doesn't have much culinary use, it has been used medicinally and as a flea deterrent and pest repellent.
“In our Lake Erie greenhouses, this cultivar produces its most vibrant foliage when given consistent morning light and steady warmth. When your order arrives, allow it to settle for 24 hours in indirect light before potting up into fresh, airy potting mix.”
— Jen Webber, Lead HorticulturistFrequently Asked Growing Questions
