The orchid shown in the picture is an Epidendrum, most likely an Epidendrum radicans hybrid. Over here in Southern Cal or other parts of the country where the weather is temperate (no snow), these guys can be grown in the garden, outdoor in the yard, straight into soil! No need to pot in barks, nuthin'! My mom used to just collect the keikis, and plant them straight into the soil in our backyard and they just grow and grow like weeds, eventually becoming a humongous bush! Just give it lot of sun, water and feed them like any garden plants! So enjoy!
