Streptocarpus Harlequin Collection
- Position: partial shade
- Soil: fertile, humus-rich, moist but well-drained soil or fibre-based compost if grown indoors
- Rate of growth: average
- Flowering period: usually throughout the year

Grown for their showy flowers, which come in a wide range of colours, these tender perennials make superb houseplants. They will flower from mid-spring to mid-autumn and tend to bloom more prolifically when slightly pot-bound. Mainly originating from woodland, rocky slopes and grassland in southern Africa, they require a frost-free position with filtered sun. Water regularly during the growing season, allowing the compost to get a little dry in-between, during this time they should also be fed with a high potash fertiliser. Overwinter in a shaded greenhouse, or indoors on an south or west-facing windowsill, watering less often. Repot each spring into a slightly larger, shallow pot filled with fibre based compost. They can also be used as summer bedding, grow in fertile, humus-rich, moist but well-drained soil in partial shade.

Which house plants you choose should depend on the environment you intend to keep them in, the space available, how much time you can spend preening them as well as your personal preference. For me, foliage house plants are the ticket, because they providRead full article
