Description: Currently considered the world's largest orchid, rare in cultivation due to its enormous size, this plant can produce flowering racemes up to 3m in length and can weigh up to 2 tons. Flowers are unique in that the lower flowers do not posess a lip, and function only as osmophores, that is they emit scent to attract pollinators but are not functional in their own right.
Plants typically only bloom every 2-4 years but can flower over a 2 month period when in bloom.
Culture: These plants are usually rare in cultivation due to their spacial requirements. Plants require direct sunlight and intermediate to warm temperatures. Keep in temperatures of 75° to 85°F in the day and 55°-6O°F in the night. Plants can tolerate temperatures up to 100°F and as low as 45°F. Plants need to be heavily fertilized during growing season. Pot in sphagnum moss or medium fir bark. Mix should be well drained. Keep area well ventilated. Water frequently in spring to early fall during growth period, but do not keep mix wet and damp. In the winter reduce watering and water when potting media is dried. 5
