  • water dropWater

    Cape primrose prefers to be watered when the top inch of soil feels dry to the touch. Typically, it might need watering once a week, but this can vary depending on environmental conditions such as temperature and humidity. Use lukewarm water and aim to water directly onto the soil to avoid wetting the leaves, which can lead to fungal diseases. Each watering session should provide enough water so that it just starts to drain through the bottom of the pot – for an average-sized pot, this might be around 8 to 16 ounces.

  • sunLight

    Cape primrose thrives in bright, indirect sunlight. A north-facing or east-facing window would be ideal for providing the gentle morning sunlight or diffused light without the harsh afternoon rays. Avoid placing the Cape primrose in direct sunlight, especially during the hot summer months, as this can scorch its leaves and fade the flowers.

  • thermometerTemperature

    Cape primrose performs well in typical indoor temperature ranges, ideally between 60 to 75 degrees Fahrenheit. It's important to keep the plant away from drafts, heating vents, and air conditioners to prevent sudden temperature fluctuations. The Cape primrose can tolerate a minimum temperature of about 50 degrees Fahrenheit, but prolonged exposure to temperatures below this can be detrimental to the plant's health.

  • scissorsPruning

    Prune Cape primrose to remove any yellowing or dead leaves and spent flowers to encourage new growth and a tidier appearance. The best time to prune is immediately after the blooms have faded. Pruning can be done sporadically throughout the year as needed, but a more thorough tidying is beneficial in late winter or early spring, just before the new growing season begins.

  • circleLife cycle

    Streptocarpus 'Katie', commonly known as Cape primrose, begins its life cycle when seeds germinate in warm, moist soil conditions, typically in spring or early summer. The seedlings quickly develop into rosettes of velvety leaves, a stage where they focus on vegetative growth and establish a strong root system. As the plant matures, usually within a few months, it begins the flowering stage, producing delicate tubular flowers that can vary in color, often in shades of blue, purple, or white. After pollination, the flowers will fade and seed pods, or 'twisted pods' (which the genus name Streptocarpus derives from), will form and mature, eventually drying and releasing seeds for reproduction. Some Cape primroses can also propagate vegetatively through leaf cuttings, where a portion of a leaf develops roots and grows into a new plant. Over time, typically after several years, the parent plant may decline in vigor, at which point it has completed its life cycle, though its progeny may continue through seeds or cuttings.

      Spring-Early Summer

    • The most popular method of propagation for Streptocarpus 'Katie', commonly known as Cape Primrose, is by leaf cuttings. This is usually done in spring or early summer when the plant is actively growing. A healthy leaf is selected and cleanly cut from the plant with a sharp knife or scissors. The leaf is then laid flat and sectioned into pieces, each piece containing a vein. These sections are placed vein-side down in a moist, well-draining soil mix, ensuring that the soil is lightly firmed around them. The container with the leaf cuttings is placed in a warm, bright area, avoiding direct sunlight, and kept consistently moist. Roots and new shoots will develop from the veins, and once they have grown sufficiently – typically after a few weeks – they can be potted up individually into their own containers.
