Origin
Crepis ephemeroides S.Moore, commonly known as the ephemeral hawksbeard, is a species of perennial plant that belongs to the Asteraceae family. It is native to North America, specifically in the western regions of the United States, such as California, Arizona, New Mexico, and Utah.
Common Names
Aside from ephemeral hawksbeard, Crepis ephemeroides S.Moore is also known by other common names, such as dwarf hawksbeard, spring hawksbeard, and western hawksbeard.
Uses
Crepis ephemeroides S.Moore has been traditionally used for medicinal purposes because of its anti-inflammatory, diuretic, and antispasmodic properties. It was used to treat various health conditions like stomachaches, bladder problems, and arthritis. However, further research is needed to validate its effectiveness.
The plant, when taken in small amounts, is edible and can be used as a salad ingredient. Its leaves and flowers have a slightly bitter taste and can be cooked as a vegetable or added to soups. However, overconsumption may cause stomach and kidney problems due to the presence of sesquiterpene lactones, which are toxic in large doses.
Crepis ephemeroides S.Moore also has significant value in the environment. It is an essential plant in the ecosystem as it serves as a food source for various insects, such as bees and butterflies, and provides cover and shelter for small animals.
General Appearance
Crepis ephemeroides S.Moore has a short stature, growing up to only 6-12 inches tall. Its stem is hairy and erect, with a rosette of basal leaves at the base. The leaves are long and narrow, with deep lobes that give them a fern-like appearance. The flowerheads grow on elongated stems and are yellow and daisy-like, with ray and disk florets. When the flowers fade, the plant produces numerous white, fluffy seeds that disperse in the wind.
Light Requirements
Crepis ephemeroides S.Moore prefers full sunlight for optimal growth. It can tolerate some shade but will not thrive in low light conditions. Therefore, it is recommended to plant it in an area that receives at least 6 hours of direct sunlight per day.
Temperature Requirements
The ideal temperature range for Crepis ephemeroides S.Moore is between 18°C to 24°C. It is a hardy plant and can withstand some fluctuations in temperature, but extreme heat or cold can affect its growth. Therefore, it is recommended to plant it in a location that provides moderate temperature throughout the year.
Soil Requirements
Crepis ephemeroides S.Moore grows well in well-draining soil that is slightly alkaline with a pH range between 7.0 to 8.0. It prefers nutrient-rich soil that is moist but not waterlogged. Therefore, it is recommended to plant it in soil that has been amended with organic matter and has good drainage. It also needs regular watering, especially during hot and dry weather.
Cultivation Methods for Crepis ephemeroides S.Moore
Crepis ephemeroides S.Moore is a hardy plant that is easy to grow and requires minimal care. The plant can be cultivated in pots or in the ground. If you are growing it in a pot, choose a container that is wide and shallow. The soil should be rich in nutrients, well-draining, and slightly acidic.
Crepis ephemeroides S.Moore prefers full sun but can also tolerate partial shade. Ensure that the plant is getting at least six hours of sunlight each day.
Watering Needs for Crepis ephemeroides S.Moore
Crepis ephemeroides S.Moore requires moderate watering. Water the plant weekly during the growing season, and reduce watering during the dormant period. The soil should be moist but not waterlogged.

Fertilization for Crepis ephemeroides S.Moore
It is recommended to fertilize Crepis ephemeroides S.Moore once every two weeks during the growing season. You can use a general-purpose fertilizer that is rich in nitrogen, phosphorus, and potassium.
Follow the instructions on the package and apply the fertilizer to the soil around the base of the plant. Be careful not to over-fertilize, as this can damage the plant.
Pruning for Crepis ephemeroides S.Moore
Crepis ephemeroides S.Moore requires minimal pruning, and it typically doesn't need to be pruned unless it has become too large. If you need to prune the plant, do so after it has bloomed in the late summer or early fall.
Remove any dead or damaged branches and cut back any overgrown stems. Be careful not to remove too much foliage, as this can affect the plant's ability to produce flowers.
Propagation of Crepis ephemeroides S.Moore
Crepis ephemeroides S.Moore, commonly known as the ephemeral hawksbeard, is a herbaceous plant that can be propagated by both sexual and asexual methods.
Sexual Propagation
The plant produces yellow flowers that turn into achenes, which are small, dry, one-seeded fruits. The achenes can be collected after they have matured in the late summer or early fall. The achenes should be sown in the fall or spring, 2-3mm deep, in well-draining soil. The soil should be kept moist, but not waterlogged. Germination can take up to 21 days.
Asexual Propagation
Crepis ephemeroides S.Moore can also be propagated asexually by division. The plant can be divided in the early spring before the new growth appears, or in the fall after the plant has finished flowering. Carefully dig up the plant, and using a sharp sterile tool, divide the plant into sections making sure that each section has some roots and shoots. Replant each division into a well-draining soil, keeping the soil moist, but not waterlogged until the plant has successfully rooted.
Disease and Pest Management for Crepis ephemeroides S.Moore
Crepis ephemeroides S.Moore is a hardy and resilient plant that can grow in tough conditions. However, like any other plant, it is susceptible to diseases and pests. Here are some common diseases and pests that might affect the plant and ways to manage them.
Diseases
1. Powdery Mildew: Powdery mildew is a fungal disease that appears as a white, powdery coating on the leaves and stems of the plant. It can weaken the plant and reduce its ability to photosynthesize. To manage this disease, apply a fungicide spray that contains copper or sulfur to the affected parts of the plant. Make sure to follow the instructions on the label to prevent any damage to the plant.
2. Rust: Rust is a fungal disease that appears as small, orange-brown spots on the leaves of the plant. It can cause the leaves to become dry and brittle. To manage this disease, remove the affected parts of the plant and dispose of them properly. Avoid watering the plant from above, as this can spread the spores of the fungi. Apply a fungicide spray that contains copper or sulfur to the remaining parts of the plant to prevent the disease from spreading.
Pests
1. Aphids: Aphids are small, soft-bodied insects that suck the sap out of the plant. They can cause the leaves to become yellow and stunted. To manage this pest, spray the plant with a strong stream of water to dislodge the aphids. Alternatively, apply an insecticide that contains neem oil or pyrethrin to the affected parts of the plant.
2. Spider Mites: Spider mites are tiny insects that produce fine silk webs on the leaves of the plant. They can cause the leaves to become discolored and fall off. To manage this pest, spray the plant with a strong stream of water to dislodge the spider mites. Alternatively, apply an insecticide that contains neem oil or pyrethrin to the affected parts of the plant.
By following these disease and pest management tips, you can help keep your Crepis ephemeroides S.Moore healthy and strong.
