General Description
Chlorocrepis fendleri, also known as Fendler's oxeye, is a herbaceous and perennial plant belonging to the Asteraceae family. It can grow up to 30-80 cm in height and 20-60 cm in width, and produces stems that are smooth and slender. The leaves are basal, forming a rosette, and are lanceolate or oblanceolate in shape, measuring 10-18 cm in length and 2-4 cm in width. The flowers are yellow and daisy-like, with a diameter of 3-4 cm, and develop in loose clusters at the top of the stems. The plant has a deep taproot system.
Origin and Distribution
Chlorocrepis fendleri is native to North America and is found primarily in the southwestern parts of the United States and northern Mexico. It thrives in a range of habitats, including rocky slopes, meadows, and open forests, and can be commonly seen in areas with high altitudes such as the Rocky Mountains and the Great Basin.
Common Names
Chlorocrepis fendleri is known by various common names, including Fendler's oxeye, yellow mountain-daisy, and Fendler's hawksbeard.
Uses
The plant has several medicinal uses, with some indigenous communities using it to treat coughs, sore throats, and gastrointestinal problems. Additionally, the plant is sometimes used as a food source for livestock and serves as a nectar source for bees and butterflies.
Light requirements
Chlorocrepis fendleri prefers to grow in full sun to partial shade. If grown in low light conditions, the plant tends to get leggy and may not produce flowers.
Temperature requirements
The ideal temperature for Chlorocrepis fendleri to grow is between 60-70°F (16-21°C). It can tolerate lower temperatures, but frost or extended periods of cold temperatures can be detrimental to the plant's growth. High temperatures can cause the plant to wilt, so it is important to keep it watered if the temperature rises above 80°F (27°C).
Soil requirements
Chlorocrepis fendleri grows well in well-draining soil that is slightly acidic to neutral. It prefers soil that is rich in organic matter, which can be achieved by adding compost or other organic material to the soil. The plant also prefers soil that is moist but not waterlogged, so it is important to water it regularly but not excessively.
Cultivation methods
Chlorocrepis fendleri is relatively easy to cultivate and grow, making it a desirable addition to gardens and landscapes. The plant can be propagated by seeds or division of mature plants.
When planting from seeds, sow them directly on the soil surface after the last frost date. The soil should be moist, well-draining, and located in full sun or partial shade. Once established, the plant can tolerate drought and heat.
When transplanting mature plants, dig a hole that is slightly larger than the plant's root ball. Gently loosen the roots before placing the plant in the hole and filling it with soil. Water the plant well after planting to promote root establishment.
Watering needs
Chlorocrepis fendleri requires moderate watering during the growing season. The soil should be moist but not waterlogged to prevent root rot. Water the plant deeply once a week or whenever the top inch of soil feels dry to the touch.
In the winter, the plant can tolerate drier soil conditions and requires less frequent watering.
Fertilization
Chlorocrepis fendleri does not require fertilization if grown in nutrient-rich soil. However, adding a slow-release fertilizer in the spring can promote healthy growth and blooming.
Be cautious not to over-fertilize, as this can lead to weak stems and foliage.
Pruning
Chlorocrepis fendleri does not require regular pruning. However, deadheading spent flowers can promote additional blooms and maintain a tidy appearance. Cut back the stem just below the spent flower to prevent the plant from producing seeds and to encourage new buds.
If the plant becomes too leggy or overgrown, it can be cut back to one-third of its height in the spring. This can be followed by light pruning throughout the growing season to maintain a compact shape.
Propagation of Chlorocrepis fendleri
Chlorocrepis fendleri, also known as Fendler's oxytrope, is a plant species that belongs to the Asteraceae family. It is a herbaceous perennial that is native to North America, specifically found in the southwestern part of the United States. Just like other plants, it needs to be propagated to increase its numbers. Here are some of the propagation methods for Chlorocrepis fendleri:
Division
Division is the simplest way to propagate Chlorocrepis fendleri. It is also the best way to rejuvenate older plants. Dividing the plant involves lifting it from the ground, separating the root ball into several parts, and replanting each new section into a new pot or garden patch. This process is best done in early spring when the plant is dormant and just starting to grow.
Seeds
Growing Chlorocrepis fendleri from seeds is also an option, although it is slightly more difficult and less successful compared to division. Seeds from mature plants can be collected in the fall before they fall out of the cones. The seeds must be sown in the spring, as soon as the ground is warm enough. The bed should be well-drained and in a sunny location. Germination occurs anywhere from one to three weeks at a temperature of 18°C to 24°C.
Cuttings
Cuttings of Chlorocrepis fendleri are a viable method of propagation, although they can be challenging to root. The process involves taking a 7 to 10 cm cutting from a parent plant. Make sure to remove any leaves and treat the cutting with rooting hormone before planting it in a well-drained soil mix. Keep the cutting moist and warm and it may take eight weeks or more to root.
Disease Management
Chlorocrepis fendleri is resistant to most fungal diseases. However, excessively moist soil can cause root rot, which leads to discolored and wilted leaves. To prevent root rot, make sure that the soil has good drainage and that you do not overwater the plant. If you notice signs of root rot, remove the affected parts of the plant and repot it in fresh, well-draining soil.
The accumulation of dead leaves and decaying organic matter around the base of the plant can attract pests and diseases. Regularly clean up the area around the plant to reduce the risk of fungal spores carrying in on diseased leaves or debris.
Pest Management
Chlorocrepis fendleri can be vulnerable to infestations by aphids, mealybugs, and spider mites. These pests can cause yellowing, stunted growth, and deformed leaves. To control these pests, use insecticidal soap or neem oil. For a large infestation, consider pruning heavily-affected leaves or using a chemical pesticide. However, these remedies should be used only as a last resort and are not suggested when it comes to ornamental plants such as Chlorocrepis fendleri.
Regularly inspect your plant for signs of pests, including yellowing leaves, chewed tissue and web-like cells. Prevention is important when it comes to pest management. It’s also essential to keep plants healthy; plants that are stressed are more vulnerable to infestations.
If you handle your Chlorocrepis fendleri regularly, make sure to wash your hands with soap and water before and after as pests can move from one plant to another with ease. Keep an eye out on nearby plants, such as herbs or flowers in the garden around the house as they could serve as hosts for pests.
