Overview:
Lomatium graveolens (S. Wats.) Dorn & Hartman, commonly known as dungreek, is a perennial flowering plant that belongs to the Apiaceae family. The plant is native to western North America, specifically found in the western parts of the United States and Mexico.
Common Names:
In addition to dungreek, Lomatium graveolens is known by several other common names, including biscuitroot, fernleaf biscuitroot, and desert parsley.
Description:
Lomatium graveolens usually grows up to 3 feet tall and bears hairy stem and leaves. The plant has a taproot that is large and fleshy, with a shape resembling a biscuit, which gives it its common name biscuitroot. The leaves are fern-like and are divided into several segments, which are narrow and toothed. The flowers of the plant are small and yellowish-white and grow in a cluster at the end of the stem.
Uses:
Lomatium graveolens has been used medicinally by Native Americans for centuries. The dried root of the plant is used to treat a variety of ailments, including respiratory infections, coughs, and digestive problems. It is also used as an immune booster and to help treat colds, flu, and other respiratory infections. The taproot of the plant is also edible, and some Native American tribes have used it as a food source.
Light Requirements
Lomatium graveolens prefers partial to full sunlight for optimum growth. It can tolerate shade, but too much shade can cause the plant to become spindly and weak. Therefore, it is recommended to grow the plant in an area with at least six hours of direct sunlight per day.
Temperature Requirements
The plant is native to the Rocky Mountains, so it can tolerate a wide range of temperatures. However, it prefers a moderate to cool climate with temperatures ranging from 50 to 75 degrees Fahrenheit. The plant becomes dormant in the summer and requires a winter dormancy period with consistent low temperatures for successful growth.
Soil Requirements
Lomatium graveolens thrives in well-draining, loamy soils with a pH ranging from 6.0 to 7.5. It can also grow in sandy or rocky soils as long as they are well-draining. The plant prefers dry to moist soil, but it cannot tolerate waterlogged soil. Therefore, it is essential to plant it in an area with good drainage.
Cultivation
Lomatium graveolens, also known as biscuitroot, is a perennial plant that is native to North America. It does best in well-drained soils with a neutral to slightly alkaline pH. The plant prefers full sun to partial shade and can grow in various types of soil, including sandy, loamy, and rocky soils. When planting, space the plants about 18-24 inches apart to allow for proper growth and airflow.
Watering Needs
It is important to keep the soil moist, but not waterlogged. Water the plant deeply once or twice a week, depending on the weather conditions and the soil moisture level. In general, Lomatium graveolens is drought-tolerant and can withstand dry periods, but it will benefit from regular watering during prolonged dry spells. Avoid overhead watering as it can cause fungal diseases. Instead, use a drip or soaker hose to water the plant at the soil level.
Fertilization
Lomatium graveolens does not require heavy fertilization. A well-composted soil will provide enough nutrients for the plant. However, you can apply a balanced, slow-release fertilizer once or twice a year to promote healthy growth. Be careful not to over-fertilize, as this can lead to excessive leaf growth and reduced flower production.
Pruning
Lomatium graveolens does not require regular pruning. However, you can remove dead or damaged stems to maintain a neat appearance and promote new growth. After the flowering season, you can cut back the plant's stems to about two inches above the ground level to encourage new growth and prevent the plant from becoming woody and leggy.
Propagation of Lomatium Graveolens
Lomatium graveolens, also known as biscuit root, is a perennial plant that belongs to the carrot family. It is commonly found in the western region of the United States, especially in the Great Basin and Rocky Mountains. The plant grows up to 60 cm tall and bears yellowish-white flowers.
Propagation Methods
Lomatium graveolens can be propagated by several methods, including seeds, cuttings, and root division.
Seeds: Seeds can be collected from the mature plants during autumn. These seeds can be sown directly into the soil during the spring. The seeds require cold stratification to break the dormancy period. This can be achieved by storing the seeds in a refrigerator for several weeks before planting. It takes around 2-3 years for the plant to reach maturity when propagated via seeds.
Cuttings: Cuttings from the stem or root of the plant can be taken during the summer. The cuttings should be around 5-7 cm in length and should have at least two nodes. The cuttings should be planted in a moist soil mix and kept in a warm, shady place. The roots should appear in 3-4 weeks, and after that, the plant can be transplanted outdoors.
Root Division: This method involves dividing the plant's roots into several pieces and transplanting them to a new location. The ideal time for performing this method is during the fall season. The roots should be carefully dug up and divided into sections, each having a shoot or bud. These divisions should be planted in a soil mix, and they should be kept moist.
Overall, Lomatium graveolens is a hardy plant that can adapt to different types of soil and climatic conditions. By using the appropriate propagation method, the plant can be easily propagated, and its population can be increased.
Disease and Pest Management for Lomatium graveolens (S. Wats.) Dorn & Hartman
Lomatium graveolens, commonly known as biscuit root or fernleaf biscuitroot, is a native plant of the western United States. While it is generally a resilient species, there are some diseases and pests that can affect its growth and health.
Common Diseases
One of the most common diseases that can impact Lomatium graveolens is powdery mildew, which presents as a white, powdery substance on the leaves and stems. This fungus can inhibit photosynthesis and stunt growth, but can be managed by pruning affected areas and applying fungicides.
Another disease that can affect the plant is leaf spot, which causes brown or black spots on the leaves. This can be caused by bacteria or fungi, and can be managed by removing affected foliage, ensuring good air circulation around the plant, and applying fungicides if needed.
Pest Management
Several pests can pose a threat to Lomatium graveolens, including aphids, thrips, and spider mites. These insects can suck sap from the plant and weaken it over time. Using insecticidal soaps or oils can help control these pests, as can introducing natural predators like ladybugs.
Gopher and rodent damage can also be a concern, as these animals can eat the roots of the plant. One way to prevent this is to bury plant containers in the ground to protect the roots, or to use wire mesh or hardware cloth around the base of the plant.
Finally, deer and other grazing animals may also feed on Lomatium graveolens. If this is a concern, installing physical barriers or using animal repellents can help protect the plant.
