Epidendrum

Epidendrum Linnaeus

The name refers to its epiphytic growth habit (epi = upon; dendrum = tree; growing on trees). When Carolus Linnaeus named this genus in 1763, he included in this genus all the
epiphytic orchids known to him. However, very few of these orchids are still included in the genus Epidendrum.

Type species is Epidendrum nocturnum Jacq., (1760).

This is now a genus of about 1100 species of evergreen epiphytic, lithophytic or terrestrial orchids. They are widespread in tropical North, Central, and South America. Most produce
cylindrical, leafy stems, other have a pseudobulbs. The flowers are produced in usually terminal, umbel-like racemes or panicles. These are mostly cool to intermediate growing orchids. Best grown in containers of epiphytic or terrestrial orchid potting mix. Provide support for long, scrambling stems. In summer, provide bright indirect light and high humidity; in winter provide full light. Water freely all year, sparingly in winter. Misting is necessary once or twice daily. Divide when the plants overflow their container. Root plantlets of species with stem as soon as they have developed vigorous roots.

Distribution and ecology They are native to the tropics and subtropical regions of the American continent, from South Carolina (USA) to Argentina. Their habitat is mostly epiphytic, a few are terrestrial or rarely growing on bare rock, such as Epidendrum calanthum and Epidendrum saxatile. Most are to be found in the Andes, at altitudes between one thousand and three thousand meters. Their habitat varies from humid jungles to dry tropical forests, from sunny grassy slopes to cool cloud forests. Many species are fragrant.
