We are very fond of streptocarpus plants. These house plants seem to be far less well known that they deserve. They are very easy to care for, provided that they are not over-watered. The trick is to wait until the leaves have flopped from lack of water. It is astonishing how quickly a little water will restore them from this. They do not need very hot rooms or direct sunlight, so thrive in our west facing windows. And they have long flowering periods, and come in lots of different colours.
