Brassidium Orchids – These Are Beautiful “Spiders” in a Beautiful Display!

Brassidium orchids and succulentsJamie put together this stunning display the other day at the front of the shop, using  a beautiful mix of containers and plants. The picture doesn’t do her designs justice,,,a  pony tail palm underplanted with succulents; another succulent planting in cork bark; and a gorgeous arrangement of a standing cork bark planter with brassidium, or spider, orchids.

The spider orchids are so exotic looking with their long, long stems holding spidery-looking flowers all along their length. These flowers actually evolved to attract a certain female parasitic wasp that lay their eggs on spiders in their webs. Since the flowers look like spiders, The wasp lays the eggs on the flower and is covered with pollen. Not getting the spider it’s looking for, it moves on to the next “spider”, thus pollinating the plant. Pretty amazing stuff.

As I’ve pointed out in other posts, the key to figuring out how to grow a plant is finding out where it’s native habitat is, and a previous post on bromeliads highlighted this. Brassia orchids are native to wet, tropical forests of Central and South America. They are named for the 19th century British botanical illustrator, William Brass.

Orchid hybridizers have crossed Brassias with Miltonia and Ondontoglossums to create some incredible hybrids, many of which are fragrant and have very large, spidery flowers.

How to grow your Brassidium orchid:

They require very bright light but not direct sun. Please don’t expect them to be happy in a dark, interior room! In the tropical forests they receive diffused light through the trees.

Keep your Brassidium orchid moist during the growing season. This is the period when the pseudobulb develops and flower spikes appear. After this period, when in flower, don’t overwater; the fat pseudobulb at the base is helping hold moisture. Water once a week or when the pot begins to feel light.

Brassidium orchids appreciate humidity, temperatures between 65F and 75F during the day, and good air circulation that can be provided by a fan. Since our homes tend to be dry, if you’d like to keep your brassia happy, add a shallow tray of pebbles in water that the pot can sit on (but not in the water). This  will help raise the humidity to the 50%-70% these orchids prefer.
