What does Dendrobium look like?

Dendrobium orchids are mostly epiphytes, growing on trees or rocks, with creeping roots and hard, sometimes cane-like pseudobulbs. Their leaves are arranged in two rows and can be linear, oblong, or cylindrical, usually lasting only one season. The flowers, which may be few or many on a stem, come in shades of white, green, yellow, pink, or purple, often with a contrasting lip. The petals and sepals are similar, but the lip is distinct, usually egg-shaped and sometimes ridged.

Where does Dendrobium come from?

The genus Dendrobium was first described in 1799 by Olof Swartz, with its name coming from Greek words meaning 'tree life', reflecting its habit of growing on trees. It includes over 1,800 species found across a wide area from the Himalayas to the Pacific islands, adapting to environments from mountain forests to dry Australian deserts. Several attempts to split the genus into smaller groups have been made, but most are not widely accepted.

When and how Dendrobium blooms

Dendrobium orchids flower from unbranched stems, with blooms that can last from a short time to several months, depending on the species. They are grown from pseudobulbs or cuttings, often attached to bark or rock rather than planted in soil. Many hybrids and cultivars have been developed for gardens and collections, with some species and hybrids in high demand among orchid enthusiasts.
