Streptocarpus Merlin

Streptocarpus ‘Merlin’ is a stunning variety from the Cape Primrose family, prized for its velvety, trumpet-shaped blooms in deep violet-purple shades, often with intricate markings that resemble hand-painted petals. Native to shaded, humid forest regions in South Africa, this hybrid has been specially cultivated for compact growth and long flowering periods – making it one of the best choices for indoor plant lovers in the UK climate.

While Streptocarpus can be placed outside in summer in a shaded, sheltered spot, they are not frost-hardy and do best as indoor plants in the UK. Treat them like flowering houseplants and they’ll reward you with colour nearly all year round.

Care Guide
Streptocarpus are surprisingly easy and bloom for months with the right care:

• Light: Bright, indirect light is best – perfect for east- or north-facing windows. Avoid direct sun, which can scorch the leaves.

• Watering: Water when the top of the soil feels dry. Avoid getting water on the leaves or crown to prevent rot. Water less in winter.

• Humidity: Prefers average to slightly higher humidity. Will thrive in kitchens, bathrooms, or grouped with other plants.

• Temperature: Enjoys 16–24°C. Keep away from cold draughts or hot radiators.

• Feeding: Use a high-potash feed (like tomato feed) every 2–3 weeks during flowering season for more blooms.

• Soil: Use a light, well-drained houseplant or African violet mix. Avoid compacted or heavy soil.

Best Placement in the Home
Perfect for windowsills, side tables, or shelves in bright rooms. Its compact size and vibrant blooms make it ideal for flats, offices, and homes with limited space but lots of charm.
