The orchid genus Epidendrum has a vast collection of over 1,000 species, derived from the Greek words “epi” and “dendron,” which mean “upon trees.” These orchids are mostly epiphytic in nature, growing on trees and absorbing nutrients from their surrounding environment through their exposed roots. Epidendrum is one of the easiest types of orchids to grow, and they can withstand full sun exposure. The orchid’s waxy and leathery leaves are available in various shades, including red, purple, yellow, orange, and white. They are perfect for indoor spaces, but if you live in warmer climates, you can try growing them outdoors. While some species of Epidendrum are dwarfs, others may grow to a height of six feet and cannot be kept as houseplants. They bloom several times of the year, usually in spring or summer, and some species thrive in low-nutrient conditions and can be grown in the ground. Crucifix orchids are characterized by their cluster of three-lobed flowers, which resemble the religious symbol. When the plant is in bloom, pseudobulbs must be kept moist, and after flowering, the plant goes dormant for several weeks. Epidendrum orchids belong to the Orchidaceae family, are evergreen, and prefer loamy, sandy, well-drained soil with an acidic pH. They can adapt to a broader range of environmental conditions than other orchid species and prefer a warm environment.
Epidendrum orchids require proper care and attention to thrive. The amount of light is crucial, as too little or too much can harm the plant. Bright but indirect light is ideal, as direct sun exposure during the summer months can be damaging. Good drainage is necessary for these orchids, so loamy, sandy soil is recommended if growing them outdoors. They do well in low nutrient potting mixes like bark mixed with perlite, gravel, moss, or coarse sand. Epidendrums need regular watering but should be allowed to dry out properly in-between. The temperature should be around the low 70s during the day and no lower than 10 degrees Fahrenheit at night, with humidity levels between 50 and 70%. These orchids benefit from a diluted mix of high-quality and balanced orchid fertilizer once every one or two weeks. Propagation is easy, as baby clones of the main plant are easily formed and can be replanted. Growing Epidendrum orchids in containers indoors is easier and less demanding, but repotting should only be done every three years if the soil looks crusty. Taller varieties may require staking or a heavier pot to keep them stable.
