The flowers are tubular, about 8-12 mm long, and can range in color from greenish-white to pink or purple. The fruit is a dry capsule with many small seeds that are dispersed by wind.
Uses
Cordylanthus kingii S. Wats. ssp. helleri (Ferris) Chuang & Heckard is used in ecological restoration projects to prevent soil erosion, and as a food source for bees and other pollinators. This plant has no known medicinal uses.
Light Requirements
The Cordylanthus kingii S. Wats. ssp. helleri plant requires full sun to grow and thrive. It needs at least 6 hours of direct sunlight each day, preferably in the morning when the intensity of the sun is not too much. The plant may not perform so well in areas that don't get enough sunlight, resulting in stunted growth and poor flowering.
Temperature Requirements
The ideal temperature range for the Cordylanthus kingii S. Wats. ssp. helleri plant is between 65 and 85°F (18-29°C). It is a warm-season plant that cannot tolerate cold temperatures and frost. It is best planted in the spring, just after the last frost when the temperatures start rising. The plant prefers warm soil temperatures as cold soil can cause the seeds not to germinate.
Soil Requirements
The Cordylanthus kingii S. Wats. ssp. helleri plant grows best in well-drained soils with a sandy to gravelly texture. The soil should also be slightly acidic to neutral, with a pH range of 6.0 to 7.0. Planting the plant in poorly drained soils like clay may cause root rot and fungal diseases. Adding organic matter to the soil can improve its fertility, which in turn enhances the plant's growth and flower production.
Cultivation Methods for Cordylanthus kingii S. Wats. ssp. helleri (Ferris) Chuang & Heckard
Cordylanthus kingii S. Wats. ssp. helleri (Ferris) Chuang & Heckard is generally found in dry, rocky, and sometimes sandy soils in arid regions. Therefore, when cultivating this plant, it is essential to mimic these conditions as closely as possible. This means planting it in a well-draining soil mix, preferably one that allows for air circulation around the roots. Additionally, the plant prefers areas with full sun exposure.
It is also important to consider the plant's natural habitat when determining its moisture needs. While Cordylanthus kingii S. Wats. ssp. helleri (Ferris) Chuang & Heckard can tolerate dry conditions, it still needs some water to maintain optimal health. To achieve this, consider watering this plant only when the soil is dry to the touch about an inch below the surface, and make sure not to overwater it.
Watering Needs for Cordylanthus kingii S. Wats. ssp. helleri (Ferris) Chuang & Heckard
As mentioned, Cordylanthus kingii S. Wats. ssp. helleri (Ferris) Chuang & Heckard prefers dry soil conditions. Therefore, it is best to avoid watering this plant frequently. Always check that the soil is dry to the touch before watering, and if you're unsure, wait a few more days to be safe. When watering, aim to water the soil directly and avoid getting any water on the leaves or flowers as this may cause damage.
Fertilization for Cordylanthus kingii S. Wats. ssp. helleri (Ferris) Chuang & Heckard
Fertilization is not typically necessary when growing Cordylanthus kingii S. Wats. ssp. helleri (Ferris) Chuang & Heckard in its natural habitat. However, if you wish to fertilize it, aim to use natural, low-nitrogen fertilizers to avoid overfeeding the plant. Consider applying a slow-release fertilizer just once a year, preferably in the late winter or early spring.
Pruning for Cordylanthus kingii S. Wats. ssp. helleri (Ferris) Chuang & Heckard
Pruning may not be necessary for Cordylanthus kingii S. Wats. ssp. helleri (Ferris) Chuang & Heckard. However, if you wish to keep the plant's shape, you can carefully trim it towards the end of its blooming season. Consider trimming away any dead or damaged stems and leaves. It's best to do this with sterile pruning shears to avoid transmitting any diseases to the plant. Alternatively, you can let the plant self-seed and multiply on its own without any pruning.
Propagation of Cordylanthus kingii S. Wats. ssp. helleri (Ferris) Chuang & Heckard
Propagation of Cordylanthus kingii S. Wats. ssp. helleri (Ferris) Chuang & Heckard is best done through the use of seeds, as this rare plant is not commonly found in cultivation. The plant is native to California and Nevada, and grows in arid and semi-arid environments. As such, the plant is adapted to drought conditions and requires minimal watering to grow.
Seed Propagation
The best time to collect seeds for propagation of Cordylanthus kingii S. Wats. ssp. helleri (Ferris) Chuang & Heckard is in the late summer or early fall, when the seed heads have matured. The seeds can be collected by gently tapping them into a paper bag, or by cutting the seed heads and shaking them into the bag.
Once the seeds are collected, they should be stored in a cool, dry place until the spring. When the temperatures rise and the soil begins to warm up, the seeds can be planted directly in the ground, about 1/4 inch deep. It is important to plant the seeds in a location that receives plenty of sunlight and has well-draining soil.
The seeds of Cordylanthus kingii S. Wats. ssp. helleri (Ferris) Chuang & Heckard have a hard coat and may require scarification before planting. This can be done by gently rubbing the seeds with sandpaper or nicking the seed coat with a sharp blade.
Once planted, the seeds should be kept moist until they germinate, which can take anywhere from two to six weeks. Once the seedlings have emerged, they should be thinned to about 18 inches apart to allow for proper growth and development.
Disease Management
Cordylanthus kingii S. Wats. ssp. helleri is a relatively hardy plant, but it can still be susceptible to certain diseases. Some common diseases that might affect the plant include:
- Rust: Rust is a fungal disease that appears as yellow or orange spots on leaves and stems. To manage rust, remove any infected plant parts and dispose of them away from the growing area. Consider using a fungicidal spray to help prevent the spread of the disease.
- Mildew: Mildew is a fungal disease that appears as white or gray powdery patches on leaves and stems. To manage mildew, improve air circulation around the plant and avoid wetting the leaves when watering. Consider treating the plant with a fungicidal spray.
- Root rot: Root rot is a fungal disease that can cause the roots of the plant to rot and decay. To manage root rot, avoid over-watering the plant and ensure there is proper drainage in the growing container. Consider repotting the plant in fresh, well-draining soil.
Pest Management
Cordylanthus kingii S. Wats. ssp. helleri is also susceptible to certain pests. Some common pests that might affect the plant include:
- Aphids: Aphids are small, soft-bodied insects that suck the sap from the plant. To manage aphids, remove them manually with a gentle stream of water or use an insecticidal soap or oil.
- Whiteflies: Whiteflies are tiny white insects that feed on the sap of the plant. To manage whiteflies, remove any infected plant parts and dispose of them away from the growing area. Consider using yellow sticky traps or insecticidal soap or oil to trap and kill the pests.
- Spider mites: Spider mites are small arachnids that feed on the plant. They are often difficult to spot but can cause significant damage to the plant. To manage spider mites, improve air circulation around the plant and keep the humidity low. Consider using a miticidal spray to control the pests.
