Appearance of Cordylanthus rigidus (Benth.) Jepson ssp. setigerus Chuang & Heckard
Hairy Bird's-beak can grow up to 3.3 feet tall, with a somewhat woody base. The stem and leaves are covered with fine hairs that give the plant its common name. The leaves are narrow and up to 2 inches long, while the flowers are small and tubular, with white or pale-pink petals.
Uses of Cordylanthus rigidus (Benth.) Jepson ssp. setigerus Chuang & Heckard
Hairy Bird's-beak is an important plant for wildlife, as it is visited by hummingbirds, butterflies, and bees. It also serves as a host plant for the endangered Bay Checkerspot butterfly. Moreover, several Native American tribes, such as the Kashaya Pomo and the Coast Miwok, utilized the plant for medicinal and ceremonial purposes.
Nowadays, Cordylanthus rigidus (Benth.) Jepson ssp. setigerus Chuang & Heckard is often planted for its ornamental value and as a component of native plant gardens or restoration projects. However, due to habitat loss and fragmentation, the plant is considered rare and in need of conservation efforts.
Light Requirements
The Cordylanthus rigidus (Benth.) Jepson ssp. setigerus Chuang & Heckard typically grows in full sun. It requires direct sunlight for at least six hours every day. The surrounding vegetation should be low so that it does not block the sun from reaching the plant. In areas with too much shade, the plant tends to grow spindly and does not produce as many flowers.
Temperature Requirements
The Cordylanthus rigidus (Benth.) Jepson ssp. setigerus Chuang & Heckard grows in a variety of temperature ranges. However, it prefers temperatures between 60°F and 80°F. It can tolerate temperatures as low as 20°F and as high as 100°F. But when the temperatures are too extreme, it may go dormant and cease to grow. Therefore, it is essential to ensure that the temperature range is adequate for its growth.
Soil Requirements
The Cordylanthus rigidus (Benth.) Jepson ssp. setigerus Chuang & Heckard thrives in well-drained, sandy soils that are rich in organic matter. It prefers slightly acidic soils with a pH range of 5.5 to 6.5. It does not do well in heavy clay soils or those that are poorly drained. The plant is also tolerant of coastal and desert soils, as long as they meet its other soil requirements. Overall, it is essential to provide the plant with the appropriate soil type for its optimal growth.
Cultivation Methods
Cordylanthus rigidus (Benth.) Jepson ssp. setigerus Chuang & Heckard is a perennial plant that is native to California. If you are planning to cultivate this plant, it's best to grow it in areas with well-draining soil and full sunlight exposure. Cordylanthus rigidus can tolerate drought, poor soils, and high temperatures, making it ideal for xeriscaping. However, it's also important to note that this plant may not do well in areas with high humidity and moist soils.
Watering Needs
When it comes to watering Cordylanthus rigidus, it's essential to keep the soil moist but not waterlogged. This plant is drought-tolerant, but it needs occasional watering during prolonged dry spells. Avoid overwatering the plant, as it can lead to root rot. Water once a week during the growing season, and reduce watering during the winter months.
Fertilization
Cordylanthus rigidus doesn't need much fertilization to thrive, but you can add a small amount of fertilizer during the growing season to promote growth and flowering. Avoid using too much fertilizer, as it can lead to excessive growth and reduce the plant's overall health. Use a slow-release fertilizer with a balanced N-P-K ratio, and apply it to the soil according to the manufacturer's instructions.
Pruning
Pruning Cordylanthus rigidus is not necessary, but you can trim back the plant after flowering to maintain its shape and size. Cut back any dead or damaged stems, and reduce the length of the remaining stems by up to half their size. Be sure to use clean, sharp pruning shears to avoid damaging the plant or introducing diseases.
Propagation of Cordylanthus rigidus (Benth.) Jepson ssp. setigerus Chuang & Heckard
Cordylanthus rigidus (Benth.) Jepson ssp. setigerus Chuang & Heckard is commonly known as Spiny bird's-beak, and it belongs to the Orobanchaceae family. The plant is native to California and is mainly found in the central and southern regions of the state. The propagation of Cordylanthus rigidus can be done through both sexual and asexual methods.
Propagation through Seeds
Propagation of Cordylanthus rigidus through seed is feasible and straightforward, and this is the most commonly used method. The seed collection should be done from mature fruits when the seeds are ripe, usually in late summer or early fall. The collected seeds should be cleaned to remove any dirt or extra plant pieces. After that, stratification is necessary to break the seed dormancy, for about three months, to help the seeds germinate.
After the stratification period, sow the seeds in pots or seed trays with well-drained soil and perlite to facilitate drainage. The sowing should be done in the spring season, and the seedlings should be watered occasionally to keep the soil moist. When the seedlings grow up to 3-4 inches, transplant them to their permanent place outdoors in a sunny location.
Propagation through Cuttings
Cordylanthus rigidus can also be propagated through stem cuttings. The cuttings should be taken from the woody part of the plant during the fall season. The cuttings should be 3-6 inches long, with a clean cut at the base, and the leaves on the lower half of the cutting should be removed.
Dip the lower end of the cutting in a rooting hormone to increase the success rate of propagation, and then plant the cutting in a soil mix with sand and peat moss. Cover the cutting with a plastic bag or a cloche to maintain moisture and warmth, and place it in bright, indirect sunlight. After a few weeks, the cutting should have developed roots, and it can be transplanted to a larger pot or outdoors to its permanent location.
In conclusion, Cordylanthus rigidus (Benth.) Jepson ssp. setigerus Chuang & Heckard can be propagated through both seed and cutting methods successfully. Growers should carefully select the propagation method that suits their conditions and time of the year to ensure successful propagation of the plant.
Disease Management
Cordylanthus rigidus (Benth.) Jepson ssp. setigerus Chuang & Heckard is relatively pest and disease-resistant plants. However, the plant may contract the following diseases:
- Mildew: affected leaves develop a white powdery film. Regularly spraying the plant with fungicides can help prevent mildew.
- Leaf spot: the plant might develop brown or black spots on the leaves. To control leaf spots, remove and dispose of the affected leaves and treat the plant with fungicides.
- Root rot: Cordylanthus rigidus (Benth.) Jepson ssp. setigerus Chuang & Heckard is susceptible to root rot. Avoid overwatering the plant and improving drainage in the soil can help prevent root rot. Fungicides can also be used to control root rot.
Pest Management
The following pests are prone to infecting Cordylanthus rigidus (Benth.) Jepson ssp. setigerus Chuang & Heckard:
- Aphids: these sap-sucking insects cause curling of leaves. You can manually remove aphids by washing the plant with insecticidal soap.
- Spider mites: these pests also suck sap from the plant and cause discolored leaves and webbing. Regularly spraying your plant with neem oil can help manage spider mites.
- Thrips: they cause distorted leaves and stunted growth of the plant. Using sticky cards or yellow traps with the plant can help catch thrips.
