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.
In this collection you will receive one plug plant of each of the following varieties:
- Streptocarpus Harlequin Blue:Producing the first flat-faced bi-coloured flowers, this compact cape primrose was voted ‘Plant of the Year’ at the RHS Chelsea Flower Show in 2010.

- Garden care: Water regularly during the growing season, allowing the compost to get a little dry in-between, during this time they should 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.

If you do nothing else...water new plants. Make sure new additions do not suffer during dry spells. Plant up summer containers bedding once the threat of frosts has passed. Feed container plants about six weeks after planting. If it’s a nice day...trim heRead full article
