Meet Reverchon’s false pennyroyal (Hedeoma reverchonii var. reverchonii), a charming little native herb that’s flying under the radar in most gardening circles. This petite perennial might not win any height contests, but what it lacks in stature, it more than makes up for in personality and ecological value.

As a member of the mint family, this delicate forb herb brings aromatic foliage and tiny, delicate flowers to your garden space. Don’t let its humble appearance fool you—this little plant packs a punch when it comes to supporting local ecosystems.

You might also see this plant listed under its synonyms Hedeoma drummondii var. reverchonii or Hedeoma lata in older references, but they’re all referring to the same wonderful little herb.

A Word About Rarity

Here’s something important to know: Reverchon’s false pennyroyal has a rarity status of S1 in Arkansas, meaning it’s critically imperiled in that state. If you’re considering adding this plant to your garden, please make sure you source it responsibly from reputable native plant nurseries rather than collecting from wild populations. By growing this rare beauty, you’re actually helping to preserve it for future generations!

Garden Appeal and Design Uses

This low-growing perennial herb makes an excellent choice for several garden situations:

  • Rock gardens where its delicate texture provides soft contrast
  • Native plant gardens focusing on regional flora
  • Xeriscapes and drought-tolerant landscapes
  • Wildflower meadows and naturalized areas
  • Aromatic herb gardens for its pleasant scent

The plant produces small white to pale purple flowers that, while tiny, create a delicate display that attracts small native bees and other beneficial pollinators. Its aromatic foliage adds sensory interest to your garden, releasing a pleasant scent when brushed against or crushed.

Growing Conditions and Care

One of the best things about Reverchon’s false pennyroyal is how easy-going it is once established. This hardy little herb thrives in USDA hardiness zones 7-9, making it perfect for much of the southern United States.

Preferred growing conditions:

  • Full sun to partial shade
  • Well-drained soils (it doesn’t like wet feet!)
  • Poor to average soil fertility—rich soils aren’t necessary
  • Excellent drought tolerance once established

Planting and Care Tips

This native herb is refreshingly low-maintenance. Once you’ve planted it in well-draining soil with good sun exposure, you can pretty much let it do its thing. Water it regularly during its first growing season to help establish a strong root system, but after that, it should handle drought conditions like a champ.

Avoid over-fertilizing or planting in overly rich soil, as this can actually reduce flowering and make the plant less robust. Sometimes, tough love is exactly what these native plants need!

Supporting Pollinators and Wildlife

While small, Reverchon’s false pennyroyal plays an important role in supporting local ecosystems. Its flowers provide nectar for tiny native bees and other small pollinators that larger flowers might exclude. Every little bit counts when it comes to supporting biodiversity in your garden!

Should You Plant It?

If you’re gardening within its native range and can source it responsibly, absolutely! Reverchon’s false pennyroyal offers several compelling reasons to include it in your landscape:

  • It’s a true regional native with deep ecological connections
  • Requires minimal care once established
  • Supports small native pollinators
  • Adds aromatic interest to your garden
  • Helps preserve a rare plant species

Just remember to source your plants responsibly from native plant nurseries, and you’ll be adding both beauty and conservation value to your garden. Sometimes the smallest plants make the biggest difference!
