Fun Facts
- 🌱 Red Awapuhi is also known as 'Red Ginger' and is native to the South Pacific, particularly Indonesia and surrounding tropical regions, where it grows wild in rainforests.
- 🌱 The waxy, long-lasting red flowers are actually modified bracts (leaf-like structures), with the true flowers being small and hidden within the inflorescence, which is why they persist so long in arrangements.
- 🌱 In Hawaiian culture, Awapuhi is considered one of the most important native gingers and is featured prominently in traditional hula performances and cultural ceremonies.
