This is a mericlone that I acquired a year ago from Kawamoto Orchid Nursery. The plant blooms 3 to 4 times per year sometimes the flowers lasts for months that this particular plant will have flowers all year long. I had to wait for overcast skies to capture the fire engine red color of the flowers. This plant is at least 6-7 years old and is very well established standing 16 inches and the widest leaf span is 11 inches; flowers at 4 inches in diameter.
*This is a plant from their Dad’s (Les Kawamoto) private growing area. He has (reluctantly) agreed to sell this plant = he rarely sells plants in his private collection. Out of the kindness of his heart he took pity on me and agreed to part with it since I begged that I really want to have an established plant than a seedling.
This came to me potted in medium bark, charcoal, lava rock, sponge rock and hydroton. I have to give it bright light south facing window, warm temperatures and high humidity all year. In summer this is outside on the fire escape and in winter it is near the heater, electric humidifier with oscillating fan given our low humidity and cold winters in Manhattan. Weekly weakly fertilizer alternated with seaweed mix and worm tea mix.
