Harvest Tips

Cut flower stems at the base with sterile scissors when blooms are fully open. Flowers last 4-8 weeks on the plant and several weeks in a vase. For propagation, divide plants after flowering by carefully separating new growths with 2-3 roots each; alternatively, propagate by keiki (baby plantlets) that may develop on mature plants.

Fun Facts

  • 🌱 Tolumnia henkelii is named after horticulturist John Henkels and belongs to the genus Tolumnia, formerly classified as Oncidium, reflecting modern orchid taxonomy revisions.
  • 🌱 This species is an epiphyte in its native habitat, growing on tree branches in humid tropical forests without any soil, which explains its preference for orchid bark media with excellent drainage.
  • 🌱 The fragrant flowers are pollinated by small bees in their native Caribbean range and often bloom multiple times per year under ideal growing conditions, rewarding patient cultivators with repeated flowerings.
