Cape primrose 'Kim' Streptocarpus 'Kim'

Water

Cape Primrose should be watered when the top inch of soil feels dry to the touch. This might be roughly once a week, but will vary based on environmental factors like humidity and temperature. Water the plant thoroughly, pouring water directly onto the soil until it begins to run out of the bottom of the pot, indicating the soil is fully saturated. It's crucial not to let the plant sit in standing water, so any excess that collects in the saucer should be emptied shortly after watering. Generally, use about a pint of water for a standard 6-inch pot, adjusting as necessary for larger or smaller pots.

Light

Cape Primrose benefits from bright, indirect light without exposure to harsh midday sun. A north-facing or east-facing window is an excellent spot, providing the soft light this plant prefers. It can also thrive under fluorescent lights, making it suitable for office spaces or areas in a home that don't receive ample natural sunlight.

Temperature

Cape Primrose thrives in temperatures between 60°F and 75°F and shouldn't be exposed to temperatures below 50°F. It prefers a stable environment without rapid temperature fluctuations. Protect your Cape Primrose from drafts and vents that could cause sudden changes in temperature.

Pruning

Pruning Cape Primrose is mainly done to remove spent flowers and withered leaves, encouraging the plant to produce new growth and more blooms. Pinch off faded blooms and any yellowing leaves at their base. The best time to prune is immediately after a flowering cycle, which can help stimulate a new flush of blooms. Depending on the plant's growth, this may happen several times a year.

Soil

The best soil mix for Cape Primrose (Streptocarpus 'Kim') is a well-draining mixture, such as one part peat moss, one part perlite, and one part loam. It is important that the mixture retains moisture without becoming waterlogged. A slightly acidic to neutral soil pH of 6.0 to 7.0 is preferable for the health and growth of the Cape Primrose.

Repotting

Cape Primrose should be repotted every 1-2 years or when it becomes root-bound. It's best to repot in the spring, which will provide fresh nutrients and encourage new growth. Always use fresh soil mix when repotting the Cape Primrose to ensure adequate drainage and prevent soil compaction.

Humidity & Misting

Cape Primrose (Streptocarpus 'Kim') thrives in moderate to high humidity levels, ideally between 50-60%. Consistent humidity is important for the plant's well-being, so using a humidifier or placing a tray of water near the plant will help maintain the desired humidity levels.

Suitable locations

• Indoor

  Keep in bright, indirect light; water when topsoil is dry.

• Outdoor

  Place in partial shade, protect from strong wind and frost.

• Hardiness zone

  10-11 USDA

Life cycle

The Streptocarpus 'Kim', commonly known as Cape Primrose, begins its life cycle as a seed, typically sown in a well-draining soil mix where it will germinate under warm, moist conditions. Once the seed germinates, it enters the seedling stage, developing its first leaves and roots, and gradually matures into a young vegetative plant. During its vegetative growth, the plant produces large, textured leaves from a basal rosette and then transitions to the flowering stage, where it forms colorful tubular flowers that can bloom throughout the year indoors. After pollination occurs, the plant may produce small, dry seed capsules that, when ripe, split open (hence the genus name "Streptocarpus" meaning "twisted fruit") dispersing seeds for new plant growth. Throughout its life, which can span several years with proper care, the Cape Primrose will continue to produce new leaves and flowers, while older leaves will wither and die, requiring removal to maintain plant health and appearance. If conditions are favorable and the plant is well cared for, it can be propagated vegetatively through leaf cuttings to produce genetically identical offspring, thereby continuing its life cycle.

Propogation

• Propogation time

  Spring to summer

• One of the most popular methods of propagating a Streptocarpus 'Kim', also known as a Cape Primrose, is by leaf cuttings. This can be done at almost any time of the year, but the best time is usually during the plant's active growing season, which is spring and summer. To propagate by leaf cuttings, select a healthy, mature leaf and cut it into pieces, ensuring each piece has at least one vein. Place the leaf pieces right side up on a moistened mix of perlite and peat moss, pressing them into the surface. Cover the propagation tray with a clear plastic to maintain humidity and keep it in a warm, brightly lit area, avoiding direct sunlight. Roots typically develop within a few weeks to a couple of months, after which you can transplant them into individual pots to grow into new plants.
