I bought an assortment of gingers and bulbs from Bangkok’s incredible Chatuchak market a few years ago. Among the succulent pile were these stout, green, segmented bulbs.
Not knowing what they were, I planted them onto a lose mixture, but instinctively keeping them above the soil. The bulbs grew quickly and vigorously. After one round of flowers, I’ve identified them to be Eulophia andamanensis.
Not a fussy plant, Eulophia andamanensis thrives in hot conditions and can even tolerate full sun. It grows quickly if planted on a rich, fast-draining soil with a bit of sand and fertilised regularly with organic fertilisers.
If you happen to grow Eulophia andamanensis, do note that this species is deciduous. It needs a prolonged 3-4 month rest period toward the end of the year or it will not flower. At the first sign of leaf-drop, keep it dry and water it only about once every 2 weeks or so.
Around February, tall spikes will emerge with small, greenish flowers that are mildly fragrant. New pseudobulbs will also start to grow.
I once made the mistake of keeping this plant growing throughout its rest period. The plant looked weak, there was some rot, and needless to say, no blooms for me that year.
