I acquired this Odontoglossum Spectatissimum from Bob Hamilton on my visit to his greenhouse on May 7, 2015. This is a species orchid, native to western Venezuela, Colombia and Ecuador in dense upper montane cloud forests at elevations of 1500m to 3200m. Thus it is a cool to cold growing epiphyte. My plant is in a bark/lava-rock mix, in a five inch pot, and has two flowers on a single spike (it appears that a taller spike was broken off on this one). The orange-brown patterning on the leaves is really striking.
This one will be a challenge for me environment. I will have to find a way to keep it cool in the summer.
