Harvest Tips

Begin harvesting leaves when plant is 6 inches tall; pinch off top 2-3 inches of stems regularly. Harvest in morning after dew dries for best flavor and aroma.

Fun Facts

🌱 Billard mint is a sterile hybrid (Mentha × piperita), meaning it does not produce viable seeds and must be propagated through runners or cuttings—preventing unwanted cross-pollination with other mint varieties in the garden.
🌱 The menthol in Billard peppermint activates cold-sensitive nerve fibers in the mouth, creating the characteristic cooling sensation that makes it valuable in confections, toothpaste, and medicinal applications.
🌱 Mint is one of the oldest herbs in recorded history, dating back to ancient Greece and Rome, where it was valued for both culinary and ceremonial purposes.
