This unusual plant is a climbing species of the Acanthaceae family. You are probably more familiar with its cousin, Black-eyed Susan, Thunbergia alata. The mysorensis is a tropical species that comes from southern India where it is used as hedging. It can grow very large, 10-15 metres is quite normal. The plant is very striking with its red and yellow slipper-like flowers which are about 5cm in length. They hang from long pendants with up to ten flowers. The individual flower can last up to a week.
The species is occasionally seen in cultivation and requires a reasonable amount of room. It is propagated by seed and by cuttings. Cuttings need a high temperature to root, ±22-25°C and a high humidity. I have never had seed on my plant, so I do not know what conditions it needs to germinate, but as it is a tropical species, a high temperature is likely. Most cuttings will root in about a month, but some take longer. If possible, plant it out in the greenhouse or conservatory, rather than keeping it in a pot, as it will do much better then. I grow it in a shaded greenhouse, but whether it needs more sun to flower, I do not know yet.
