Origin and Common Names
Sutera henrici Hiern, also known as Bacopa henrici, is a flowering plant native to eastern and southern Africa, particularly in Zimbabwe and South Africa. It belongs to the family Plantaginaceae and is commonly known as the White Bacopa or Snowflake Sutera.
Appearance
The Sutera henrici Hiern is a small, herbaceous perennial plant that grows up to 10-12 inches in height. It has trailing stems with small, oval-shaped, and succulent leaves that are about 0.5 inches long. The plant produces delicate, white, star-shaped flowers measuring about 0.6 inches in diameter with a yellow center. Flowers appear from late spring to fall and bloom in clusters at the end of each stem.
Uses
Sutera henrici Hiern is commonly used as an ornamental plant due to its delicate white flowers that bloom abundantly, and its trailing habit that makes it an excellent choice for hanging baskets, containers, or as ground cover. It performs best in partial shade to full sun and well-drained soil. The plant is easy to grow and maintain, making it a popular choice for gardeners. Its branches root at the nodes, allowing it to spread quickly and form dense mats. Moreover, its succulent leaves store water, enabling the plant to tolerate periods of drought.
Light Requirements
Sutera henrici Hiern thrives best in bright, indirect light. Direct, intense sunlight can scorch and damage the leaves of the plant. Therefore, it is recommended to place the plant in a location that receives partial shade during the day.
Temperature Requirements
The plant grows best in temperatures between 60°F to 80°F (15.5°C to 26.7°C). Sutera henrici Hiern is somewhat tolerant of temperature changes, but it is best to avoid exposing the plant to extreme temperatures. Cold drafts and sudden temperature fluctuations can harm its growth and cause leaf drop.
Soil Requirements
Sutera henrici Hiern prefers well-draining soil that is rich in organic matter. A mixture of peat moss, perlite, and vermiculite can be an ideal choice. The soil pH should be slightly acidic, between 5.5 to 6.5. It is recommended to avoid using heavy soils that may cause waterlogging and root rot.
Water Requirements
The plant enjoys moist but well-draining soil. It is best to avoid over-watering, which can lead to root rot. Allow the soil to dry out slightly between watering sessions. It is also essential to avoid getting water on the leaves as it can cause fungal diseases.
Fertilizer Requirements
Sutera henrici Hiern benefits from regular applications of a balanced, water-soluble fertilizer during the growing season. Use a fertilizer that has a ratio of 10-10-10 or 20-20-20 and apply it every two weeks. The plant should not be fertilized during the dormant season.
Cultivation methods
Sutera henrici Hiern, commonly known as Cape primrose, is a herbaceous plant that belongs to the family of Scrophulariaceae. It is native to South Africa, primarily found in the Cape Province. The plant grows well in well-draining and fertile soil, and it prefers soil pH between 5.5 and 6.5. For better growth, it is recommended to place it in a partially shaded area with a temperature range of 15°C to 25°C.
Watering needs
When it comes to watering, Cape primrose requires moist soil. However, overwatering should be avoided as it can lead to root rot, which ultimately affects the plant's lifespan. It is recommended to water the plant thoroughly and then allow the soil to dry partially before watering again. During the winter season, watering needs to be reduced as the plant's growth rate is relatively slow during this period.
Fertilization
Cape primrose is a heavy feeder; thus, regular fertilization is required to ensure its proper growth and development. Fertilizers rich in nitrogen and potassium are recommended for this plant species. Slow-release fertilizers are preferred as they provide continuous feeding. Fertilization needs to be carried out once a month, during the growing season.
Pruning
Pruning is essential for maintaining the plant's attractive appearance. It is recommended to pinch the growing tips regularly to encourage bushier growth. Deadheading faded flowers is also essential to promote continuous blooming. In addition, regular pruning can be carried out in the spring season to remove damaged or dead stems.
Propagation of Sutera henrici Hiern
Sutera henrici Hiern is a beautiful flowering plant that belongs to the family of Scrophulariaceae. The plant is commonly known as the Cape Primrose or the Fairy Bells. It is widely used for ornamental purposes due to its attractive flowers. Propagation is an important aspect of gardening and plays a crucial role in maintaining the plant's population. Let us explore the various propagation methods of Sutera henrici Hiern.
Seed Propagation
Sowing seeds is the most common method of propagating Sutera henrici Hiern. The seeds are small and should be sown on the surface of the soil mixture, rather than being buried. Keep the soil moist and place the container in a warm, bright location. Germination can take up to four weeks. Once the seedlings have grown big enough, transplant them into their individual pots and continue to care for them.
Cuttings Propagation
Propagation via cuttings is a popular method for propagating Sutera henrici Hiern. Cuttings should be taken during the growing season from the tip of the plant and should include at least two or three nodes. Place the cutting in a well-draining soil mix with a rooting hormone and keep it moist. Once the roots start to develop, transplant the rooted cuttings into their individual pots.
Division Propagation
Division propagation is a simple method of propagating Sutera henrici Hiern. You can divide the plant when it has grown too large for its current pot. Carefully remove the plant from its container and gently separate the roots. Repot each division into a new container with fresh soil mixture. Make sure to water them regularly and keep them in a warm, bright location until they adapt to their new environment.
In conclusion, Sutera henrici Hiern can be propagated using different methods. Growing from seeds is suitable for those who have the patience and time to wait for the seeds to germinate. Taking cuttings is perfect if you want to produce more plants quickly. Lastly, division propagation is highly recommended for those who want to keep the plant population under control. Implementing these propagation methods will help you succeed in propagating Sutera henrici Hiern.
Disease and Pest Management for Sutera Henrici Hiern

Common Diseases
Sutera Henrici Hiern is prone to several common diseases, including:
- Leaf Spot: This fungal disease causes circular brown or black spots on the plant's leaves and can lead to leaf drop.
- Powdery Mildew: This fungal disease appears as a white powdery coating on the plant's leaves, stems, and flowers.
- Root Rot: This disease is caused by overwatering or poor drainage and can lead to wilting, leaf yellowing, and root decay.
Disease Management
To manage these common diseases:
- Remove infected plant parts, dispose of them properly, and sterilize your gardening tools between cuts.
- Water the plant at the base, avoid wetting the leaves, and provide proper drainage for the soil.
