Origin
Lophochlaena californica Nees var. davyi (L. Benson) A.& D. Löve is a type of flowering plant that is native to California and can be found growing in the southwestern regions of the U.S. and northwestern regions of Mexico.
Common Names
The plant is commonly known as Davy's lomatium or Davidson's lomatium and is a member of the Apiaceae family. Other common names include Indian carrots, desert parsley, and biscuitroot.
Uses
Lophochlaena californica Nees var. davyi has been traditionally used for medicinal purposes by various Native American tribes. The roots and seeds of the plant were used to treat respiratory ailments, colds, and coughs. The plant was also used as a food source and as a natural dye.
General Appearance
The plant grows up to a height of 1 to 3 feet with a spread of up to 1.5 feet. It has a woody stem and feathery, green leaves that are finely divided and have a distinct smell. The plant produces clusters of white or yellow flowers that bloom from March to July, which are followed by seed-filled, narrow pods. The root of the plant is thick and fleshy, with a strong odor.
Light Requirements
Lophochlaena californica Nees var. davyi typically grows in areas with full sun exposure but can tolerate partial shade as well. This plant needs an average of 6 hours of sunlight per day to thrive.
Temperature Requirements
This plant is usually found in areas with a Mediterranean climate, which is characterized by mild, wet winters and hot, dry summers. In general, it can tolerate a wide range of temperatures, but it grows best in regions with an average temperature between 55° F and 80° F. This plant can tolerate frost and temperatures as low as 25° F for short periods.
Soil Requirements
Lophochlaena californica Nees var. davyi prefers well-draining, sandy soil with a slightly acidic to neutral pH (around 5.5-7.0). It can grow in a variety of soil types, including loam, clay, and rocky soil. This plant is adapted to growing in drought conditions, so it can tolerate dry soil, but it also benefits from occasional watering during prolonged dry periods.
Cultivation Methods
Lophochlaena californica Nees var. davyi (L. Benson) A.& D. Löve, also known as the Davy's California marigold, is a drought-tolerant plant that is hardy in USDA plant hardiness zones 8 to 10. It prefers well-draining soils and a full-sun to partial-shade location. The plant can grow up to 3 feet tall and 3 feet wide, so it needs enough space for proper growth.
Watering Needs
When it comes to watering, Lophochlaena californica Nees var. davyi can handle drought-like conditions and requires little irrigation. However, young plants and those grown in containers may require more frequent watering to become established or prevent drying out. It's essential to avoid overwatering, as it can lead to root rot.
Fertilization
Lophochlaena californica Nees var. davyi doesn't require regular fertilization. The plant can grow on poor soils, and overfertilization can lead to excessive foliage growth at the expense of blooming. If the soil is too poor, you can add some compost or well-rotted manure to help improve the soil structure and provide some nutrients.
Pruning
Lophochlaena californica Nees var. davyi doesn't require extensive pruning. However, deadheading spent flowers can help to encourage prolonged blooming and prevent self-seeding, which can sometimes be unwanted. You can also prune the plant to promote bushier growth and remove any damaged or diseased branches. The ideal time for pruning is in late winter or early spring, before the plant begins to actively grow again.
Propagation of Lophochlaena californica Nees var. davyi (L. Benson) A.& D. Löve
Lophochlaena californica Nees var. davyi (L. Benson) A.& D. Löve, commonly known as Davy's Tree Echinacea, is a perennial shrub native to California and southern Oregon. The propagation of this plant is possible through various methods, including seed propagation, stem cutting propagation, and division propagation.
Seed Propagation
Seed propagation is one of the easiest and most common methods used for the propagation of Lophochlaena californica. The plant produces large quantities of seeds yearly, usually in fall. The seeds are light and can be readily wind-dispersed. It's essential to ensure the seeds are collected and stored in dry conditions to maintain their viability. Sow the seeds in a fertile, well-drained soil mix, covering them to a depth of about twice the diameter of the seed. Water the seeds regularly and maintain a warm temperature between 20-25° C. The germination period of Lophochlaena californica varies between 2-6 weeks.
Stem Cutting Propagation
Propagating Lophochlaena californica through stem cutting is possible during the growing season. Take cuttings from the parent plant in the summer, avoiding the woody parts. The cuttings should be approximately 10-15 cm long. Remove the leaves from the lower half of the cuttings, leaving two to three leaves intact at the top. Dip the cut end of the stem into a rooting hormone and plant it in a potting mix of perlite and peat moss. Provide the cuttings with ample water and shade to promote the development of roots. The cutting will take around three to four months to root and be ready to transplant.
Division Propagation
Division propagation is another method used to propagate Lophochlaena californica. The best time to divide the plant is in early autumn or spring. Carefully dig up the entire plant and separate it into smaller sections, making sure each section has a root system and foliage. Replant each section in a suitable soil mix in a separate container or directly in the garden. Water the divided plants and provide them with shelter from the sun initially until they become established.
Successful propagation of Lophochlaena californica can be achieved through any of the above methods, depending on the suitability and availability of the materials. It's essential to provide the young plants with adequate water and shelter initially to ensure their growth and survival.
Disease Management
Lophochlaena californica Nees var. davyi (L. Benson) A. & D. Löve is a relatively resistant plant. However, some diseases can affect it:
- Rusts: These fungi cause orange to brown pustules on the leaves and stems. Rusts can be controlled with a copper-based fungicide.
- Phytophthora root rot: This disease is caused by a pathogen that attacks the roots, causing the plant to wilt and die. Management of phytophthora root rot can be done through adequate drainage and limiting irrigation.
Pest Management
Although Lophochlaena californica Nees var. davyi (L. Benson) A. & D. Löve is generally pest resistant, some pests can infest the plant:
- Aphids: These sucking insects can cause stunted growth, yellowing, and distortion of the leaves. Aphids can be managed through natural predators like lady beetles or through the application of insecticidal soaps or oils.
- Slugs and Snails: These mollusks can cause damage to the plant by eating holes in leaves and stems. Slugs and snails can be controlled by using bait stations or placing copper barriers around the plant.
Regular inspection of the plant can help identify any pest infestations or symptoms of diseases. Early detection and intervention are key to successful management of pests and diseases in Lophochlaena californica Nees var. davyi (L. Benson) A. & D. Löve.
