10 streptocarpus to grow

Discover 10 colourful streptocarpus houseplants to grow, in our pick of the best.

Native to South Africa, Streptocarpus – or Cape primrose – makes a fantastic houseplant in the British Isles. They come in a huge range of flower colours, and bloom from spring though to autumn, offering a long-lasting indoor display. They’re easy to grow and even easier to propagate. The key to growing streptocarpus is to find a bright window sill away from direct sunlight, and avoid over-watering. Streptocarpus are native to wooded mountain areas, so thrive in dappled shade and free-draining soils.
