This is the Naked Man Orchid found in the Mediterranean area and like all the orchis is summer dormant. it grows well in an alpine house where it can be protected from winter rain. The plants offered may have either a plain or spotted rosette. Whilst the photograph and name attract people to the plant it is definitely not for the beginner, especially someone without an alpine house. They need the cold of the winter but not the wet. The idea that they could be grown in a conservatory will definitely not work and it is highly likely the plant will become stressed and die.
Tubers are sent out potted to UK customers. With this species this usually from AUGUST to DECEMBER but the amount of growth may prevent this.
