Black and White Orchids

Black Orchids

• The Smithsonian Gardens notes on its website that “true black” is not a color that exists with respect to flowers. A flower that is called black is actually a dark maroon or purple that appears black at first glance. For example, the national flower of Belize, the black orchid, has a dark purple and yellow bloom. The slipper orchid, which is a popular flower for beginning orchid growers, counts “almost black” in its nearly 60 species, according to the University of Tennessee.

White Orchids

• White orchids can be found among the easiest-to-grow varieties of orchids, notes the University of Tennessee. Corsage orchids, or cattleya, originate in areas from Brazil to Mexico and typically grow in trees. Phaelenopsis, or moth orchids, can produce up to 30 blooms from a single plant and can bloom for up to four months. Most of its 44 varieties are from the Philippines. Paphiopedilum, or slipper orchids, bloom in white as well as “almost black,” and originate in India, the Philippines and China.

Care

• Care for “black” and white orchids varies depending on the species. The color alone does not dictate the care regimen for the flower. The University of Tennessee notes that cattleya needs good drainage and aeration to grow well. Phaelenopsis thrives in 60 to 70 percent humidity and can survive in water for one week after being cut. Paphiopedilum, which produces a black bloom, must be repotted every one or two years.

Considerations

• The University of Tennessee Extension reports that insufficient lighting is the most common reason an orchid will not bloom. Windowsills are the best location for indoor orchids, and artificial lighting can be used if needed. When growing orchids indoors, you may need to use a humidifier to maintain the 50 to 70 percent humidity levels the plants need in order to grow. Keep your black and white orchids clean by giving them a warm shower twice a year.
