Jumellea comorensis (Rchb.f.) Schltr.

This beautiful species from the Comores Islands has pure white, brillant, 5 cm big flowers if grown in a greenhouse. Yes, I did grow the species in a room with gigantic windows, an average temperature of 21°C and a very low humidity (sometimes only 25%). In that condition, altough the plant grew well, the flowers ware not bigger than 3 to 3,5 cm. The plant easily grows to big clumps and divisions can be made from rooted cuttings.
Remackable: the leaves, when touched, smell chocolate.
