Plants for a hot, sunny conservatory
I have a large conservatory with wide windowsills just crying out for plants (once the trays of seeds have been planted out - and squeezed in between my tender plants being overwintered).
Although its North facing, in the summer it gets full sun from about lunchtime until 8pm or so. We have no shading or blinds so although we open windows and the door, it does get very hot in the full sun. In the winter its heated and kept at a minimum of approx 14degrees.
Any ideas for foliage rich, colourful, floriforous plants which could survive the full sun without being scorched would be great. At the moment I have some Christmas cactus (which have been spectacular), a couple of aloes and sempervirums and a cactus. I also have a carnivorous pitcher plant which loves these conditions. Previously I have had scented geraniums but do have problems with whitefly and red spider mite.
I was thinking about something colourful like a Hibiscus - does that like full sun? Any ideas gratefully received - I would prefer plants to be kept on the windowsills rather than larger planters to be kept on the floor (as I have a very old cat who would use anything as a loo rather than go outside in the rain!).
