Cape primrose 'Sioned' Streptocarpus 'Sioned'

Water

For the Cape Primrose, it's vital to water it well when the surface of the soil feels dry to the touch, typically every 5 to 7 days depending on environmental conditions. Use room temperature water and avoid wetting the leaves to prevent fungal diseases; water from beneath or use a watering can with a long spout to direct water to the soil. A thorough watering that allows a little water to flow through the drainage holes is ideal, but be cautious not to leave the plant sitting in water. As a rough guideline, aim for about 8-16 ounces of water for a standard 6-inch pot, adjusting as necessary for your specific conditions and pot size.

Light

The Cape Primrose thrives in bright, indirect light; place it near a window where it can receive plenty of light without being exposed to the harsh midday sun. A north- or east-facing window is often ideal, offering the gentle light this plant prefers.

Temperature

The Cape Primrose prefers temperatures between 60 to 75 degrees Fahrenheit and can tolerate a minimum temperature of 50 degrees Fahrenheit. To ensure healthy growth, keep the plant away from drafts and sudden temperature changes which can cause stress to the plant.

Pruning

Prune the Cape Primrose to remove spent flowers and yellowing leaves to encourage new growth and blooming. The best time for pruning is immediately after a bloom cycle has finished, which can be at various times throughout the year depending on the plant's environment.

Cleaning

As needed

Soil

Cape Primrose requires a light, fast-draining soil mix with added perlite or vermiculite. A pH balance of around 6.0 to 7.0 is ideal for optimal growth.

Repotting

Cape Primrose should be repotted annually, preferably in spring or after it finishes blooming, to refresh the soil and provide room for growth.

Humidity & Misting

Cape Primrose thrives in high humidity, maintaining levels around 50-60% for optimal plant health and bloom production.

Suitable locations

• Indoor

  Place Cape Primrose in bright, indirect light and keep soil slightly moist.

• Outdoor

  Grow Cape Primrose in dappled shade; protect from afternoon sun.

• Hardiness zone

  10-11 USDA

Life cycle

Cape Primrose 'Sioned' begins its life cycle when seeds germinate in warm, moist soil, typically taking between two to four weeks to sprout. The young seedlings then develop into a rosette of leaves, which gradually matures and begins to produce flowering stalks. These stalks can blossom in a variety of colors depending on the variety, with 'Sioned' producing blooms that persist for several weeks. After flowering, if the flowers are pollinated, the plant can produce seed pods that twist open to disperse seeds, completing the reproductive cycle. Even without pollination, Cape Primrose 'Sioned' can be propagated vegetatively by leaf cuttings, allowing for the creation of clone plants. Throughout its lifetime, which can be several years with proper care, 'Sioned' requires periods of growth and dormancy, with reduced watering in cooler months to simulate a natural environment.

Propogation

• Propogation time

  Spring-Summer

• Propogation: Streptocarpus 'Sioned', commonly known as Cape Primrose, is predominantly propagated through leaf cuttings. This method is popular because it is straightforward and effective. It's best to propagate in late spring or early summer when the plant is in its active growth phase. A healthy leaf should be chosen, preferably one that is neither too young nor too old. The leaf is cut across into sections, each with a vein, and then the sections are placed either directly into a potting mix or into a water medium to root. In the potting mix, they are placed vein-side down and lightly covered with soil; if water rooting is used, each piece should be suspended with the cut edge submerged. Rooting typically occurs in about four to eight weeks, after which individual plantlets will soon begin to form at the base of the cuttings. After a sufficient root system has developed, they can be potted individually into their own containers with a well-draining potting mix.
