Dendrobium Orchid (Dendrobium spp.)

The Dendrobium species are the most popular orchids because of their ease of culture and prolific flowering habits. The orchids in this genus often develop a long reed-like stem with a typical length of more than one foot. Some appear densely covered with short white hairs. Short, ovate leaves grow alternately over the length of the stems. The white, lavender, and combination colored flowers are produced on long arching racemes. Flowers open gradually and may remain open for three to four weeks.
