Fun Facts
- 🌱 Despite its common name 'Elfin Herb,' Heuffelii is not truly an herb but a woody shrub native to the mountains of Mexico, where it grows in warm, subtropical regions.
- 🌱 The plant's scientific name Cuphea comes from the Greek word 'kuphos' meaning 'curved,' referring to the curved seed capsules that develop after flowering.
- 🌱 Heuffelii is often confused with its relative Cuphea llavea (Bat-faced Cuphea), but can be distinguished by its finer foliage and smaller, more abundant flowers.
