Description How to Grow More Info Delivery

Streptocarpus ‘Harlequin Delft’ is a large and free-flowering variety which bears violet-blue flowers, 5.6cm across, with pale yellow lower lips and finely etched deep purple veins in the throat.  Height: 30cm (12in). Spread: 40cm (16in). 

Streptocarpus make stunning houseplants. Clusters of exotic-looking blooms are produced for at least nine months of the year in an endless array of vibrant shades and colour combinations, rising on slender stems above rosettes of wrinkled, green leaves. They create a superb focal point on a sunny windowsill or in the conservatory. Striking good looks and an easy going nature make this Cape Primrose a perfect gift for beginners and seasoned growers alike.

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

March to September

Place your Streptocarpus in a bright spot in indirect light. Do not expose to hot, direct sunlight. An east or west-facing windowsill is perfect. Water regularly as the compost begins to dry out but avoid letting the plant sit in water. Feed fortnightly with a proprietary houseplant feed. As the plant grows, repot as necessary in spring into a slightly larger pot.

October to February

Move to a south facing windowsill if possible. Only water when the compost dries out and don’t feed. Remove any dead leaves and debris to minimise the chance of pests and diseases.

Feed and water regularly throughout the growing season. Deadhead faded flowers to encourage more blooms to be produced. In winter, allow the compost to dry out slightly in between waterings.
