Fun Facts

- 🌱 The soft, downy texture of the foliage—which gives the plant its common name 'Downy Myrtle'—is due to fine hairs that help the plant reduce water loss in warm climates.
- 🌱 In its native habitat and tropical regions, the berry-producing season can be nearly year-round, but in subtropical zones it typically concentrates into a summer-fall harvest window.
