Epidendrum radicans Reed-stem orchids

Easy-to-grow outdoor orchid

The easiest of all orchids to grow in Southern California is a reed-stem orchid, so called because it flowers atop a 2- to 3-foot reed-like stem, tall enough to peek over a flower bed or a balcony railing.

Though the botanical name, Epidendrum , means “upon trees,” the most common epidendrums are terrestrial orchids, growing in the ground and not attached to treetops. They are easy to grow but shouldn’t be overwatered or planted in too heavy a soil.

In pots, they can grow in ordinary potting soil, or in that coarse bark sold for orchids, and they will not flinch if you forget to water for a few weeks. They do need a sunny location if they are to flower, though garden lore says they do best if their roots are shaded.

One place they are seldom seen--but where they do exceptionally well--is at the back of a flower border, even mixed in with perennials. With their roots shaded by the plants in front, and their sometimes skimpy foliage partially hidden, their flowers will add color throughout the year.

The flowers are small, like miniature cattleyas, but there are many in long-lasting clusters. They come in a variety of colors, though the deep red (usually a species, Epidendrum obrienianum) , orange and purple are the most common. Most are sold by color, however there are named varieties.

Almost all are hybrids, though they may be called Epidendrum radicans , or E. ibaguense , two names for one of the parent plants.

Santa Barbara Orchid Estate (1250 Orchid Drive, Santa Barbara 93111; (805) 967-1284) sells these and many other colors and even offers a reasonably priced trial selection of five colors.

These are also the easiest of plants to propagate once you have a start. A short time after flowering they will produce keikis--or baby plants--at the ends of the stems.

As soon as these have roots a few inches long, cut them off and plant them. In fact where ever roots appear along the stem, you can cut just below and restart the plant.
