Seed germination in sterile nutrients is now a common way to reproduce orchids.
STEVE EMBER: Mericloning also is a common modern method. The process calls for culturing from the merismatic tissue on a plant. Active growth takes place in that area. In the process, a small piece of tissue is taken from a high quality orchid. The tissue is made into tiny pieces and grown in a laboratory. Many exact copies of the orchid are produced. Whether grown naturally or through technology, people who love orchids say they are the most beautiful flowers on Earth.
