  • water dropWater

    Cape Primrose should be watered when the top inch of soil feels dry to the touch, which typically means once a week but can vary with environmental conditions. It's important to use lukewarm water and to water the plant from below by filling the saucer so the roots can draw water upwards. This helps avoid getting water on the leaves, which can lead to rot. An average-sized Cape Primrose might need around 8 to 16 ounces of water during each watering session. Adjust the amount of water given according to the size of your plant and the humidity level of the room.

  • sunLight

    Cape Primrose thrives in bright, indirect light, making an east- or north-facing window ideal for this plant. Direct sunlight, especially during the hottest parts of the day, can scorch the leaves, so it should be avoided or filtered through curtains. Adequate lighting will promote healthy growth and abundant blooms.

  • thermometerTemperature

    Cape Primrose prefers temperatures between 60-75 degrees Fahrenheit for optimal growth. It can survive minimum temperatures down to about 50 degrees Fahrenheit but avoid sudden temperature changes and keep it away from cold drafts. The warmth of a typical home interior suits this plant well, making it an appropriate houseplant.

  • scissorsPruning

    Prune Cape Primrose to remove any dead or yellowing leaves and spent flowers, promoting healthier growth and rejuvenating its appearance. The best time to prune your Cape Primrose is after a bloom cycle has completed, usually in late winter or early spring. Pruning every few months will encourage the plant to produce more blooms.

  • circleLife cycle

    The life cycle of the Cape primrose (Streptocarpus 'Harriet') begins with seed germination, where the tiny seeds need light and warmth to sprout, usually taking several weeks. Once germinated, seedlings develop a rosette of leaves, characteristic of young Streptocarpus plants, and this vegetative stage can last for a few months as the plant grows. Following vegetative growth, the Cape primrose reaches maturity, characterized by the production of long, thin flower stalks bearing trumpet-shaped flowers that come in a variety of colors, blooming periodically throughout the year, especially when indoor growing conditions are favorable. After the flowering stage, pollination can occur, often with the help of insects, leading to the development of seed pods (the "streptocarpus" fruit) that twist and burst open when dry, dispersing seeds for reproduction. In perennial growing conditions, the plant will enter a period of dormancy, generally during the cooler, darker months, reducing growth and flowering activity. With proper care, Cape primrose can resume vigorous growth and flowering during its active growing seasons, completing its life cycle annually for several years.

    • Propogation time

      Spring-Early Summer

    • Propogation: Streptocarpus 'Harriet', commonly known as Cape Primrose, can be propagated primarily through leaf cuttings. The best time to propagate is during spring or early summer when the plant is actively growing. To propagate by leaf cuttings, a healthy leaf is selected and a portion of it is cut across the width, preferably with a bit of the main stem attached. This cutting should ideally be about 2 to 3 inches (approximately 5 to 7.5 centimeters) long. The leaf segment is then placed in a moist, well-draining potting mix, covering the cut edge slightly with the soil. In a warm environment with indirect light, the cutting will develop roots and eventually sprout new growth. This method is favored because it maintains the characteristics of the hybrid and is generally successful and straightforward.
