Harvest Tips
Harvest flowers when fully developed and colored (buds won't open after cutting). Cut at the base of the flower spike in early morning when stems are turgid. Heliconia flowers have exceptional vase life of 2-4 weeks. Can be dried for long-term arrangements. Cut regularly to encourage more blooms. Wear gloves as leaf edges can be sharp.
Fun Facts

- 🌱 Native to Peru and Ecuador, this plant was named after Mount Helicon in Greek mythology, home of the Muses, reflecting its stunning ornamental beauty.
- 🌱 In nature, Heliconia rostrata is pollinated almost exclusively by certain hummingbird species whose beak shape perfectly matches the curve of the flower spike, a remarkable example of coevolution.
