This perennial species comes from Sri Lanka and India, specifically from the western Ghats of Tamil Nadu, and is one of the late flowering sorts. It is flowering in my greenhouse at the moment and the flowers are white with splashes of red and between 5 and 7 cm in size. It requires warmth (15-20°C) to do well; it can be kept at 10°C but will not grow or flower so well in cooler conditions. When the temperatures are right and it is kept in a shady place, it can grow into a real bush of up to one or one and a half metres in height. It needs to be cross-pollinated to obtain seed which I have been doing this year and to catch the seed I have used empty teabags which works very well. Perhaps I will get enough seed to be able to offer it on the webshop next year.
