 dendrobium-orchids

Dendrobium orchids, with over a thousand species under its name, display remarkable diversity when it comes to its flowering behavior, appearance, growing condition, and also has an impressively wide geographical distribution.

Given its seemingly countless species, cultures, and hybrids, plus their complicated nature, orchid experts and botanists are finding it hard to break down the dendrobium orchid genus into a smaller genus.

Fast Facts About Dendrobium Orchids

The name Dendrobium is a combination of the Greek words "dendron" (tree) and bios (life) respectively, which is in reference to its epiphytic nature (living on trees).

Botanical Name: Dendrobium (den-DROH-bee-um)
Common Name: Stalk orchids
Family: Orchidaceae
Subfamily: Epidendroideae
Tribe: Dendrobieae
Subtribe: Dendrobiinae
Genus:  Dendrobium
Growing type: Epiphyte (on trees) and Symbodial (vine-like)

Dendrobium orchids flower during summer and remain dormant in winter. Their flowers appear at the end of a long stalk, which can grow as long as eight feet. (This also explains their common name.) These stalks are also called flower spikes.

Interestingly, there are types of this orchid plant whose flowers last only fleetingly, say, a few hours. On the contrary, there are also dendrobium orchids whose blooms last as long as 10 months, such as the Dendrobium cuthbersonii, which holds the record for the most long-lasting flower in all of the plant kingdom.

Dendrobium Orchid Species, Sections, and Hybrids

Olaf Swartz, a Swedish botanist and taxonomist, discovered dendrobium orchids in 1799.
