Harvest Tips

Berries are ready to harvest when completely dark purple-black, typically 2-3 months after flowering. Gently pick berries by hand or allow to drop naturally.

Fun Facts

  • 🌱 Lena is a South Asian native that has been cultivated as an ornamental in the tropics and subtropics for centuries, with historical records of use in traditional medicine dating back hundreds of years.
  • 🌱 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.
