Epidendrum radicans is a species of orchid. Common names include ground-rooting epidendrum, fire-star orchid, rainbow orchid, and reed-stem epidendrum. It is a common roadside weed at middle elevations in Central America. It is a crucifix orchid, often confused with many other members of the section , including E. calanthe, E. cinnabarinum, E. denticulatum, E. erectum, E. fulgens, E. ibaguense, E. imatophyllum, E. incisum, E. schomburgkii, E. secundum, and E. xanthinum, among others. The diagnostic characteristic of E. radicans is its tendency to sprout roots all along the length of the stem; other crucifix orchids only produce roots near the base. Additionally, E. radicans flowers are resupinate, unlike the members of the Epidendrum secundum complex, E. fulgens, and many other crucifix orchids. E. radicans also differs from E. secundum by bearing no nectar in the flower.

E. radicans, like other members of subgenus Amphiglottium, is a sympodial orchid which grows stems which do not swell into pseudobulbs and are covered with imbricating sheaths, produces a terminal inflorescence covered at its base by close imbricating sheaths, and produces a lip adnate to the column to its apex. The lip of E. radicans is trilobate, as with the other members of section , with the lacerate lobes which are typical of the subsections Carinata and Tuberculata. E. radicans differs from the other lacerate Schistochila by producing roots from most of the stem.
