Softhair False Pennyroyal: A Fragrant Texas Native Worth Protecting
Meet softhair false pennyroyal (Hedeoma mollis), a charming little Texas native that’s flying under the radar in most gardening circles. This perennial herb might not win any beauty contests, but it’s got personality in spades – and a conservation story that makes it worth knowing about.
What Makes This Plant Special
Softhair false pennyroyal is a true Texan through and through. This aromatic herb belongs to the mint family and produces tiny white to pale lavender flowers that may be small, but they pack a fragrant punch. As a perennial forb, it lacks the woody stems of shrubs but comes back year after year, forming low-growing patches that add subtle texture to native plant gardens.
Don’t let the name fool you – while it’s called false pennyroyal, it has its own distinct character and shouldn’t be confused with true pennyroyal species.
