Most orchids in cultivation are epiphytic, growing upon trees, rocks, and decomposing material instead of rooting into the ground. They have fleshy roots and stems that have a white coating called velamin. This coating helps to absorb water and nutrients. There are thousands of orchid species, highly variable in their requirements. Each species requires a different balance of temperature, humidity, light, water, fertilizer, media, ventilation, etc.

Scientific Name

I. Botany/History

  • Family: Orchidaceae
  • Growth Habit:

Most orchids in cultivation are epiphytic, growing upon trees, rocks, and decomposing material instead of rooting into the ground. They have fleshy roots and stems that have a white coating called velamin. This coating helps to absorb water and nutrients. There are thousands of orchid species, highly variable in their requirements. Each species requires a different balance of temperature, humidity, light, water, fertilizer, media, ventilation, etc.

  • Origin:

Native orchids have been found growing on every continent except Antarctica. New species are being discovered all of the time. In 1789, the Royal Botanic Gardens were cultivating 15 species. During the folling 50 years, orchid mania swept over Europe. Currently, the major countries from which U.S. companies import orchids from are Taiwan, Thailand, and the Netherlands.
