WaterCape primrose should be watered when the top inch of soil feels dry to the touch, which will typically be once a week, but this can vary depending on environmental conditions. It's better to err on the side of underwatering rather than overwatering, as Cape primrose does not like to sit in waterlogged soil. When watering, gently pour water at the base of the plant until it begins to drain from the bottom of the pot. Depending on the size of the pot, this might be around 8 to 16 ounces for smaller pots and up to a gallon for larger ones, but always make sure excess water is able to drain away to avoid root rot.
LightCape primrose thrives in bright, indirect light. Placing it near an east or north-facing window where it can receive a few hours of gentle morning sunlight or late afternoon light is ideal. Avoid direct midday sun, as it can scorch the leaves of the plant. If natural light is limited, fluorescent grow lights also work well for Cape primrose.
TemperatureCape primrose prefers temperatures between 60 and 75 degrees Fahrenheit, with a minimum of 50 degrees to avoid cold damage and a maximum of 80 degrees to prevent heat stress. The ideal conditions include consistently warm temperatures without significant fluctuations, so avoid placing the plant near drafts or heat sources that could cause sudden temperature changes.
PruningPrune Cape primrose regularly to remove spent flowers and encourage bushier growth. Deadheading, or the removal of faded blooms, should be done as needed to keep the plant looking tidy and to promote further flowering. Best done after the main flowering flush, additional light pruning can be carried out to shape the plant and manage its size.
CleaningAs needed
SoilThe Cape Primrose requires a well-draining soil mix, ideally composed of peat moss, perlite, and vermiculite, in a ratio of 2:1:1. These plants thrive in slightly acidic to neutral soil, aiming for a pH range between 5.8 and 7.0 for optimal growth and flowering.
RepottingCape Primroses should be repotted annually to refresh the soil and accommodate root growth. It is best to repot in spring or early summer before the growth season peaks, ensuring they have room to thrive each year.
Humidity & MistingCape Primroses prefer a moderate to high humidity level, ideally around 50-60%. Keeping them in a well-humidified room or using a humidity tray can create the right environment for healthy growth without the need for frequent watering.

Life cycleCape Primrose 'Frosty Diamond' begins its life cycle as a seed, which, when sown in a well-draining soil mix and kept warm and moist, will germinate. The seedling emerges with a set of initial leaves and, over time, develops into a young plant with characteristic fuzzy foliage. As the plant matures, it produces larger leaves and starts to form flower stalks; each stalk may bear multiple blossoms known for their velvety texture and white color with speckled variegation. Following the flowering stage, the plant can produce capsules that contain seeds, completing its reproductive cycle. Vegetatively, Cape Primrose 'Frosty Diamond' can also propagate through leaf cuttings, where a leaf or a portion of it is used to grow a new plant. Over time, the plant will experience a period of dormancy, typically in the winter months, where growth slows before resuming in the spring.

Spring-Early Summer
The Streptocarpus 'Frosty Diamond', commonly known as Cape Primrose, can be propagated most effectively through leaf cuttings, a popular method utilized by enthusiasts of this plant. To propagate by leaf cuttings, select a healthy, mature leaf and cut it across horizontally; smaller leaves can be used whole. Then, insert the cut end into a moist, well-draining potting mix. Keep the potting soil consistently moist and place the pot in a warm, bright area without direct sunlight, which may scorch the delicate cuttings. In a matter of weeks, small plantlets should begin to appear at the base of the cutting. Once these plantlets have grown to a reasonable size, typically a few inches in height, they can be gently separated and potted individually to grow on as new Cape Primrose plants.
