This is the one orchid I can count on to flower. I don't even have to do anything special. It doesn't get enough light, sometimes it gets too much and gets scorched, sometimes it gets too much water, sometimes not enough, sometimes it gets really hot, other times it gets really cold, fed or not fed this is a truly rewarding orchid.

I have just added a closeup image of a flower from this plant which shows the cruciform feature. The plant is growing outdoors in my garden in a frostfree area of San Diego, CA. Sunset Western Garden Book states that radicans (or ibaguense, as they prefer to call it) originated in Colombia, S. A., and can stand brief temperatures down to 28 degrees F. with minimal damage. Cultivars exist in various colors: yellow, orange, pink lavendar and white. I find the lavendar type to be particularly beautiful. Diluted, high-nitrogen liquid fertilizer is beneficial during the growing season. This plant grows readily from cuttings. WalterT.

This plant branches freely, and throws out lateral growths and aerial roots quickly. Best grown on where support of the lateral growths can be provided, like next to a fence. Radicans tolerates a wide variety of temperature conditions as well. Can be used to form a low hedge. I saw one at a botanical garden that is growing about 50 feet from a salt water bay, facing west.

Epidendrum radicans bears a densely flowered head of long-lasting red/orange flowers, with yellow throats, which rises above the foliage.
