Light Requirements
Cyrtandra ellipticifolia requires a moderate amount of light to grow well. It prefers bright but indirect light rather than direct exposure to the sun. It can thrive in partially shaded or dappled light conditions, such as under a canopy of trees. If grown indoors, it should be placed near a window where it receives bright, indirect light.
Temperature Requirements
Cyrtandra ellipticifolia is a tropical plant and prefers a warm and humid climate. The ideal temperature range for this plant is between 60°F (15.6°C) to 80°F (26.7°C). It cannot tolerate temperatures below 50°F (10°C) or above 90°F (32.2°C), which may cause damage to the leaves and overall growth of the plant. If grown indoors, it is essential to maintain a warm and stable temperature and avoid placing the plant in cold drafts.
Soil Requirements
Cyrtandra ellipticifolia requires a well-draining soil that retains moisture without becoming waterlogged. It is best to use a rich and fertile soil mix with a high content of organic matter. A pH range between 5.5-6.5 is optimal for this plant. It can also benefit from regular fertilization, especially during the growing season, to promote healthy growth and flowering. Adding compost or mulch to the soil can help retain moisture and provide necessary nutrients for the plant.
Cultivation Methods
Cyrtandra ellipticifolia St. John is a tropical plant native to Hawaii that prefers a warm and moist environment. It is commonly grown as an indoor plant or in a greenhouse in areas with cooler climates. The plant can also be grown outdoors in USDA hardiness zones 10 to 11. It requires well-draining soil that is rich in organic matter. When potting the plant, use a combination of peat moss, perlite, and sand. Place the pot in a location that receives bright, indirect sunlight.
Watering Needs
Watering is an essential part of Cyrtandra ellipticifolia St. John's care routine. The plant's soil should be consistently moist, but not waterlogged. Check the soil regularly, and water the plant when the top inch of the soil feels dry to the touch. Be sure to use room-temperature or lukewarm water as cold water can shock the plant's roots. Overwatering can cause the roots to rot, so avoid leaving the plant in standing water.
Fertilization
Cyrtandra ellipticifolia St. John should be fertilized every two weeks during the growing season (spring and summer) with a balanced fertilizer (10-10-10). During the dormant season (fall and winter), reduce fertilization to once a month. Be sure not to over-fertilize the plant as it may lead to leaf burn or stunted growth.
Pruning
Pruning should be done during the plant's dormant season to encourage healthy growth and maintain its shape. Trim back any yellow or brown leaves and cut back any leggy stems to promote bushier growth. Pinch off stem tips to encourage lateral branching. Be sure to use sterilized pruning shears to prevent the spread of disease.

1. Propagation by Seeds
Propagation by seeds is a reliable method of producing new plants of Cyrtandra ellipticifolia St. John. The method is suitable for people who want to grow the plant from scratch. Here are the steps involved in propagating using seeds:
- Collect mature capsules and extract the seeds. You can harvest the seeds from dry capsules and spread them evenly in a tray.
- Add a layer of peat moss and soil to the tray, ensuring it's well-draining.
- Cover the tray with a plastic bag to retain moisture.
- Place the tray in a warm, bright location, but not in direct sunlight.
- Keep the soil moist by spraying water regularly and remove the plastic bag if necessary to prevent mold growth.
- The seeds germinate in two to six weeks. And after six months, you can transplant the plants into the garden.
2. Propagation by Cuttings
Propagation by cuttings is also an easy way of growing Cyrtandra ellipticifolia St. John plants, and it's suitable for propagating the plant to improve the density of an existing plant. Here are the steps involved in propagation by cuttings:
- Choose a mature plant with healthy leaves.
- Cut a 6-inch stem from the mother plant.
- Strip the leaves on the bottom half of the stem and coat the end in rooting hormone.
- Place the stem in well-draining soil and cover it with a plastic bag to retain humidity.
- Place the pot in a place with bright, indirect light, and maintain the soil's moisture level.
- The cuttings form roots within four to six weeks. After the roots form, you transplant them into a larger pot or garden bed.
Propagating Cyrtandra ellipticifolia St. John is easy and a great way to add to your collection of plants. Whether by seed or cuttings, you can easily grow new plants and enjoy their stunning flowers and foliage.
Disease and Pest Management for Cyrtandra ellipticifolia St. John
Cyrtandra ellipticifolia St. John, also known as Hawaiian Campanula, is a beautiful and exotic plant that requires proper care to thrive. One of the critical aspects of taking care of this plant is managing the various pests and diseases that may attack it. Some of the common diseases and pests that may affect Cyrtandra ellipticifolia St. John include:
Diseases
1. Anthracnose: This is a fungal disease that causes the leaves to become brown and yellow. The disease spreads quickly and can lead to the plant's death. To manage anthracnose in Cyrtandra ellipticifolia, remove and destroy the infected leaves and increase ventilation around the plant.
2. Root rot: This disease occurs when there is excess moisture around the plant's roots, leading to the roots' decay. To manage root rot in Cyrtandra ellipticifolia st. John, ensure proper drainage of the soil and avoid overwatering the plant.
3. Leaf spot: This disease causes the leaves to develop small spots that turn brown and yellow. The spots may spread and cause the leaves to drop off. To manage leaf spot, remove the infected leaves and improve air circulation around the plant.
Pests
1. Mealybugs: These pests cause the leaves to develop a sticky residue that attracts ants. To manage mealybugs, wipe the leaves and stem with a damp cloth, and use insecticidal soap or neem oil.
2. Spider mites: These pests are tiny and can be difficult to see. They cause leaves to yellow and develop small brown spots. To manage spider mites, increase humidity around the plant and use insecticidal soap or neem oil.
3. Aphids: These pests suck the sap from the plant's leaves, leading to yellowing and stunted growth. To manage aphids, spray the plant with a solution of water and dish soap, or use insecticidal soap or neem oil.
Regular monitoring of your Cyrtandra ellipticifolia St. John plant can help identify and manage any diseases and pests before they cause significant damage. Proper care and management will help keep your plant healthy and beautiful.
