Dendrobium Gatton Sunray gx (Orchid)


Dendrobium Gatton Sunray gx (Orchid) is a large orchid boasting long, arching to pendulous racemes crowded with soft yellow, fragrant flowers, 2 in. across (6 cm), with a burgundy wine colored lip. Blooming in the spring, Gatton Sunray is a magnificent orchid hybrid originated by Colman in 1919. It is a cross of Dendrobium pulchellum and Dendrobium Illustre.

  • Grows up to 2-3 ft. tall (60-90 cm).
  • Grows in bright indirect light with good ventilation.
  • This plant should be kept moist during the growing season. 
  • This plant needs a dry winter rest. It must be exposed to moderately low temperatures, 55°F (13°C), to induce flowering. Maintain high light during this period and reduce watering to just enough to keep the plant from shriveling. Fertilization can be reduced to quarter strength or stopped completely. Watering must be increased when the buds on the nodes start to swell for best flowering.
  • Propagate by division when the plant over-fills the pot.
  • Repot immediately after flowering, when new roots begin to grow.
  • Generally disease free. Keep an eye out for aphids, glasshouse red spider mite and mealybugs.

Tip for reblooming

  • If a plant is healthy but does not produce flowers in a reasonable time, then increase the light, and your orchid should get back on track blooming regularly.
