Dendrobium (Orchids)


Dendrobium is a diverse genus of more than 1000 orchids species distributed throughout tropical and subtropical Asia, the islands of the south Pacific and Australia. These orchids are usually epiphytic (growing on trees), lithophytic (growing on rocks) and rarely terrestrial.

Dendrobium orchids have a sympodial growth habit and produce new stems (pseudobulbs) at the base of the previous year’s stems. Their elongated stems bear linear to ovate leaves that can be evergreen or deciduous depending on the species.

Racemes of showy and delicate flowers are produced from nodes along the stems mainly in spring. They can last one day to many weeks, depending on the species, and come in an array of pastel colors.

As an added bonus, some species are sweetly fragrant.

Since the Dendrobium genus is so large and complex, the cultural requirements of these spectacular orchids will depend on their native habitat and the section of the genus to which they belong. All Dendrobium require frost-free conditions and some need warm and humid tropical conditions. Many need a dry resting period in cooler temperatures once new growth has stopped and before flowering.The dendrobium genus is classified into 6 distinct groups, each with its own culture and care requirements. It is important to know what type of Dendrobium you have in order to grow it properly.
