It is a member of the family Gesneriaceae and is endemic to the Hawaiian Islands. The plant is usually found in wet forests at elevations ranging from 800 to 1100 meters above sea level.
Common Names:
The plant is commonly known as Caudate Sepal Cyrtandra, a name that most likely refers to the long, tapering sepal of the plant, which has a tail-like appearance.
Appearance:
C. ×caudatisepala is a herbaceous plant with hairy stems. The plant can grow up to a height of about 50 cm. The leaves of the plant are arranged in an alternating, spiral pattern and are typically oblong to elliptic in shape, reaching a length of 25 cm and a width of 9 cm. The flowers of the plant are tubular and bell-shaped with five petals. The flowers tend to be about 1.5 cm long and come in shades of pink or lavender. The long, tapering sepal of the plant is about 4.5 cm long and curves downwards, giving the plant a unique appearance.
Uses:
The Caudate Sepal Cyrtandra is cultivated as an ornamental plant due to its attractive flowers and unique appearance. The plant is easy to grow and is a good choice for tropical gardens or indoor cultivation. The plant prefers well-drained soils and partially shady conditions. Further research is required to determine the medicinal value of the plant.
Light Requirements
Cyrtandra ×caudatisepala St. John requires bright, indirect sunlight to thrive. It should be placed near a window that provides bright, indirect light. Direct sunlight can scorch the leaves and cause damage to the plant.
Temperature Requirements
The ideal temperature range for Cyrtandra ×caudatisepala St. John is between 60°F to 75°F (15°C to 23°C). It cannot tolerate temperatures below 50°F (10°C) or above 85°F (29°C). Keep the plant away from drafts and sudden temperature changes, as this can cause stress and damage to the plant.
Soil Requirements
Cyrtandra ×caudatisepala St. John prefers well-draining soil that is rich in organic matter, such as peat moss. The soil should be kept evenly moist, but not waterlogged. Use a pot with drainage holes to prevent the soil from becoming too wet. The plant can be fertilized every 2-3 months with a balanced fertilizer to promote healthy growth.
Cultivation
Cyrtandra ×caudatisepala St. John (pro sp.) requires a warm and humid climate to grow, preferring daytime temperatures of 73-78°F and nighttime temperatures of 60-65°F. This plant can be grown both indoors and outdoors, but it does best in a shady and protected outdoor environment such as a shaded patio or porch.
The soil should be mildly acidic, with a pH range of 6.0-6.5. A well-draining and loose potting mix is ideal for indoor potted plants, while garden beds should be enriched with organic matter like compost or aged manure.
Propagation is best done through stem cuttings during the warmer months of the year. Once rooted, the young plants can be transplanted to a larger pot or bed with rich, well-draining soil.
Watering Needs
Cyrtandra ×caudatisepala St. John (pro sp.) prefers moist soil with good drainage. Water the plant thoroughly when the soil surface feels dry to the touch, but avoid overwatering, which can cause root rot. For indoor plants, it is best to water from the bottom up, allowing the plant to soak up water through the drainage holes. For outdoor plants, watering in the early morning or late evening can help prevent excess evaporation.
Fertilization
Cyrtandra ×caudatisepala St. John (pro sp.) benefits from regular fertilization to encourage healthy growth and flowering. Use a balanced fertilizer every four to six weeks during the growing season, diluting it to half strength. Avoid fertilizing during the dormant season, as it can cause leaf burn or damage to the plant's roots.
Pruning
Cyrtandra ×caudatisepala St. John (pro sp.) requires minimal pruning, but it can benefit from shaping after flowering to maintain a neat and compact appearance. Deadheading spent flowers can also encourage new blooms. Trim back any yellow or dead leaves to prevent pest and disease problems.
Propagation of Cyrtandra ×caudatisepala St. John
Cyrtandra ×caudatisepala St. John can be propagated through various methods including:
Seeds
Seeds can be obtained from a mature plant and sown directly into soil. The seeds need to be kept moist and warm until germination occurs, which can take several weeks. Once the seedlings have emerged, they can be transferred to individual pots and grown until they are large enough to be planted outdoors.
Cuttings
Cuttings can be taken from a mature Cyrtandra ×caudatisepala St. John plant in the spring or early summer. A 2-3 inch cutting can be taken from the tip of the plant and planted in potting soil. It is important to keep the soil moist and warm and to provide adequate light for the cutting to grow. Once the cutting has grown a strong root system, it can be transferred to a larger pot or planted outside.
Division
Cyrtandra ×caudatisepala St. John can also be propagated through division. This method involves separating the root ball of a mature plant into smaller sections, each with their own stem and root system. These smaller sections can then be transplanted into individual pots or planted outside. Division is best done in the spring or fall when the plant is not actively growing.
Disease and Pest Management for Cyrtandra ×caudatisepala St. John
Cyrtandra ×caudatisepala St. John is a beautiful plant to have indoors or outdoors at home. However, it is susceptible to diseases and pests that can ruin its beauty and health if not properly managed. Here are some common diseases and pests that might affect this plant and ways to manage them.
Diseases
Cyrtandra ×caudatisepala St. John can be affected by bacterial and fungal diseases. Bacterial wilt is the most common disease that affects this plant. The symptoms of bacterial wilt include yellowing and wilting leaves, and the stems may have brown streaks. To manage bacterial wilt, remove and destroy infected plants, maintain good sanitation practices, and avoid over-watering.
Fungal diseases such as leaf spot and powdery mildew are also common in this plant. Leaf spot causes small brown spots on leaves, and powdery mildew causes a white powdery substance on the leaves. To manage fungal diseases, remove infected leaves, avoid watering the foliage and maintain good air circulation.
Pests
Cyrtandra ×caudatisepala St. John can be affected by common pests such as spider mites, mealybugs, and aphids. Spider mites cause webbing on the leaves and leave a stippled appearance. Mealybugs and aphids both suck the sap from the leaves, causing discoloration and stunted growth. To manage these pests, use an insecticide soap or oil, keep the plant clean, and maintain good air circulation.
In conclusion, Cyrtandra ×caudatisepala St. John is a great plant to have. However, it is important to be aware of the different diseases and pests that might affect it and take measures to manage them properly. These measures include maintaining good sanitation practices, avoiding over-watering or watering foliage, removing infected leaves, and using an insecticide soap or oil.
