Named after the 19th century Danish botanist and scientist Anders Sandoe Oersted, this genus was originally part of the genus Epidendrum; however, it was separated about 35 years ago and is a separate genus today. Unfortunately, some continue to call them “Purple-Warted stem Epidendrums”.

There are about 35 species, all found in humid temperate forests of Central America and South America, mostly as epiphytes, rarely as lithophytes or as terrestrials.

The plants grow up to 60 cm tall, the roots are thick and succulent, and the inflorescence it terminal. It can flower at any time of the year but it flowers predominantly during the spring, the same time as most Epidendrums.

The numerous flowers are small, waxy in appearance, predominantly mauve but also white and orange, and are long lived and resemble Epidendrum flowers.

In “captivity”, Oerstedella orchids require temperate climate with day temperatures from 15°C and 25°C and night temperatures from at least 12°C to 18°C. Partial shade, good humidity and air circulation are important.

Like Epidendrums, Oerstedella orchids produce aerial roots at the end of their stems. Good watering during the growing season and less during the winter.

All species are best grown mounted. General speaking, the conditions required are very similar to those required by Epidendrums. Best propagated by division.
