WaterCape Primrose should be watered when the top inch of soil feels dry to the touch, approximately every 7 to 10 days, but this can vary based on environmental conditions such as temperature and humidity. Use room temperature water and gently water the soil until it is evenly moist without being waterlogged; the excess should be allowed to drain away. It is best to water from below or at the soil line to avoid wetting the leaves, which can cause problems. Depending on the pot size, watering with about one to two ounces of water at a time may be sufficient for small pots, while larger pots may need up to a quart.
LightCape Primrose thrives in bright, indirect light, making an east- or north-facing windowsill an ideal location. They can tolerate some morning sun, but direct afternoon sun should be avoided as it can scorch the leaves. If the natural light is too intense, diffusing it with a sheer curtain or moving the plant back from the window can help provide optimal lighting conditions.
TemperatureCape Primrose prefers a comfortable room temperature, ideally between 60 to 75 degrees Fahrenheit. The plant can tolerate temperatures as low as 50 degrees Fahrenheit for short periods but should be kept away from cold drafts. Similarly, temperatures above 80 degrees Fahrenheit can cause stress to the plant, so it's best to maintain a consistent temperature within the recommended range.
PruningPrune Cape Primrose to remove faded or dead flowers and leaves, which encourages new growth and more blooms. Light pruning can be done throughout the year as needed, but a more thorough pruning should occur in late winter or early spring, which is the best time for the plant to recover rapidly. Regularly removing spent flowers will also prevent the plant from putting energy into seed production.
CleaningAs needed
SoilThe best soil mix for African Violet siblings like the Streptocarpus 'Harlequin Delft' is light and well-draining, consisting of peat moss, vermiculite, and perlite in equal parts. The ideal soil pH should range between 5.8 and 6.2 for optimal growth.
RepottingStreptocarpus 'Harlequin Delft' should be repotted every 12 to 18 months to replenish its soil and allow room for growth. However, avoid over-potting as they prefer to be somewhat root-bound.
Humidity & MistingStreptocarpus 'Harlequin Delft' thrives best in moderate to high humidity levels, ideally between 50-60%. They can tolerate humidity slightly outside this range, but consistent levels help promote healthier foliage and blooms.
Suitable locationsIndoor
Place in bright, indirect light and keep soil moist.

Life cycleStreptocarpus 'Harlequin Delft', commonly known as Cape Primrose, begins its life cycle with seed germination, which typically occurs in a warm, moist environment. As a seedling, it develops its first pair of leaves and must have consistent moisture and good light to continue to grow. The vegetative stage is marked by the growth of larger, fuzzy leaves in a rosette pattern, which can last for several years as the plant is a perennial. As it reaches maturity, Cape Primrose produces vibrant and patterned flowers that emerge from the base of the leaves, attracting pollinators. After pollination, the flowers fade, and seed capsules develop, which then dry and split to release seeds for reproduction. Outside of this cycle, the plant may enter a dormancy phase in response to cooler temperatures or periods of less light, after which it can resume active growth.
PropogationPropogation time
Spring-Early Summer
Propogation: The Streptocarpus 'Harlequin Delft', commonly known as Cape Primrose, is typically propagated through leaf cuttings, a method that can be performed at virtually any time of year, although spring and early summer are ideal for faster growth due to warmer temperatures and longer daylight hours. The most popular method of propagation is by using a healthy, mature leaf. The leaf is cut across the width into pieces about 1.5 to 2 inches (approximately 3.8 to 5 centimeters) long, making sure that each piece has a main vein. These leaf sections are then planted in a moist, well-draining potting mix, with the cut edge inserted into the soil. Over the next several weeks, with consistent moisture and indirect light, each leaf cutting can produce one or more new plants from the base of the leaf section, as the vein area typically has the highest concentration of plant hormones that stimulate root and shoot formation.
