This enchanting member of the mint family is one of Hawaii’s botanical treasures—and like many island natives, it’s become increasingly rare in the wild.

Its delicate white to pale lavender tubular flowers may be small, but they pack a punch when it comes to supporting Hawaii’s native pollinators.
As a member of the mint family, this phyllostegia shares that characteristic aromatic foliage that releases a pleasant fragrance when brushed against. It’s like having a little piece of Hawaii’s natural heritage right in your garden.
Where Does It Call Home?
Smallflower phyllostegia is endemic to Hawaii, meaning it exists nowhere else on Earth. This native plant has adapted specifically to Hawaiian growing conditions and plays an important role in the islands’ unique ecosystems.
