Gregg’s Tube Tongue: A Hidden Gem for Southwest Native Gardens
If you’re looking for a low-maintenance native perennial that brings subtle beauty and ecological benefits to your garden, let me introduce you to Gregg’s tube tongue (Justicia pilosella). This charming little forb might not have the flashiest name, but it’s got plenty of character and deserves a spot in more southwestern gardens.
What is Gregg’s Tube Tongue?

You might occasionally see this plant listed under its various historical names, including Siphonoglossa pilosella or Monechma pilosella, but Justicia pilosella is its current accepted botanical name.
