- Roots grow all along its stem, unlike related crucifix orchids
- Flowers appear throughout the year in red-orange with yellow tips
- Grows on rocks in full sun in mountain cloud forests
- Part of an ecological group showing convergent evolution
- Chromosome counts vary: 2n = 40, 57, 60, 62, or 64
What does Fire star orchid look like?
Fire star orchid is a ground-growing orchid with upright or sprawling stems that can reach 1.5 metres. Its thick, leathery leaves clasp the stem, sometimes showing a hint of purple. The showy flowers are red-orange with yellow-tipped petals. A distinctive three-part lip at the centre gives the plant its 'crucifix' name.
Where does Fire star orchid come from?
It occurs naturally from Mexico through Central America to Colombia and Venezuela. It thrives on rocky outcrops in full sun within cloud forests and other mountain habitats between 900 and 2500 metres elevation. Though native to this region, it often appears as a roadside plant at mid-elevations.
When and how Fire star orchid blooms
This orchid blooms year-round, sending up flower spikes that may branch and last a long time. It grows best in well-drained, sandy or loamy soil under full sun or light shade. Temperatures between 10°C and 27°C suit it, and it tolerates poor nutrients. Propagation is easy from stem cuttings or plantlets that form on the stems.
Kinds of Fire star orchid
It belongs to a group of similar orange-flowered orchids in section Schistochila, such as E. ibaguense and E. secundum. Unlike most of them, it produces roots along nearly the entire stem. Genetic studies suggest it may be distinct enough to warrant its own subsection within the group.
What Fire star orchid means
Its bright flowers share habitat and pollinators with unrelated plants like Asclepias curassavica and Lantana camara. Scientists have studied whether these species mimic each other’s blooms, but found no clear proof that this affects pollination. The orchid’s seeds are tiny, about 320 per milligram.
