Origin
Astragalus leucolobus S. Wats. ex M.E. Jones ssp. consectus (Sheldon) Abrams is a species of the Astragalus genus, which belongs to the legume family. This plant is native to the western United States, specifically in the intermountain and Great Basin areas. It has been recorded in Arizona, California, Idaho, Montana, Nevada, Oregon, Utah, and Wyoming.
Common Names
Astragalus leucolobus S. Wats. ex M.E. Jones ssp. consectus (Sheldon) Abrams has several common names, including Sheldon's milkvetch, Sheldon's astragalus, and Sheldon's locoweed. The plant is named after Edwin James "Ned" Sheldon, who was a botanist and spent his career studying the flora of the Great Basin area.
Uses
The plant has been used as forage for livestock, particularly for sheep and cattle. It has been noted that when Sheldon's milkvetch is grazed upon, it can cause a neurological disorder in livestock known as "locoism" if they consume too much of it. In traditional medicine, the roots of the plant have been used as a poultice for boils and as a remedy for rheumatism, coughs and colds, and stomach ache. However, it is important to note that this plant should not be consumed by humans or animals without proper research and guidance from a medical professional.
General Appearance
Astragalus leucolobus S. Wats. ex M.E. Jones ssp. consectus (Sheldon) Abrams is a perennial herb that grows up to 20 cm tall. The plant has a branched stem, with leaves that are pinnately compound and have 3-5 leaflets. The flowers are yellow in color and are arranged in clusters at the end of the stem. The plant produces a legume fruit that is 1-3 cm long, which contains several seeds. The roots of the plant are long and fibrous.
Growth Conditions for Astragalus leucolobus ssp. consectus
Astragalus leucolobus ssp. consectus is a plant species that thrives in dry and hot environments. It is generally found in desert habitats, on rocky slopes, and in crevices of cliffs, where it grows at an elevation of 1,000-4,000 feet above sea level. These plants have a woody base and herbaceous stems, which can reach 30-80 cm tall.
Light Requirements
Astragalus leucolobus ssp. consectus plants require a significant amount of light to grow and mature. They typically grow in areas with full sun exposure as well as partial shade. In areas with extreme heat, partial shade may be necessary to provide adequate protection from the sun. If grown indoors, the plant must be placed near a sunny window at a warm temperature.
Temperature Requirements
Astragalus leucolobus ssp. consectus plants are accustomed to extreme temperatures and can tolerate very high temperatures. These plants can grow in temperatures ranging from 20-35°C (68-95°F) during the daytime. They can also tolerate temperature drops below freezing for a short time. However, extreme cold temperatures can damage the plant, so it is important to provide adequate protection during the winter.
Soil Requirements
Astragalus leucolobus ssp. consectus plants require well-draining, sandy or gravelly soils. These plants have a shallow root system, and they prefer soils that are not too wet. If the soil is too wet, it will lead to root rot, which can damage or kill the plant. To ensure proper drainage, it is recommended to mix some sand or small rocks in the soil before planting. This will help prevent excess moisture buildup and provide the necessary drainage to keep the plant healthy.
Cultivation Methods
The Astragalus leucolobus S. Wats. ex M.E. Jones ssp. consectus (Sheldon) Abrams plant can be cultivated in various types of soil, but it prefers sandy soil that is well-drained. It also needs to be placed in a location with full sun exposure. The best time to plant is during fall or early spring. The process involves loosening the soil and adding organic matter or compost before planting the seedlings. The plant can also be propagated through seedlings or cuttings.
Watering Needs
Watering is a crucial aspect of this plant's care routine. Adequate watering is needed to keep the soil moist, but the plant should not be overwatered. It's best to water deeply but not frequently, allowing the plant to establish deep roots that can withstand drought. Always make sure to check the soil before watering the plant to avoid oversaturation.
Fertilization
Fertilization must be carried out every year during the growing season, which is in the spring and summer months. The plant requires balanced fertilizers that can supply it with the vital nutrients needed for healthy growth. Ensure not to over-fertilize the plant as this can harm its growth.
Pruning
Pruning is essential for maintaining the plant's health and aesthetics. The Astragalus leucolobus S. Wats. ex M.E. Jones ssp. consectus (Sheldon) Abrams plant should be pruned in the fall to prevent it from becoming too leggy. It's best to use sharp pruning tools to create clean cuts, and the pruned parts must be removed from the plant to avoid rotting. Pruning can also be done to remove dead or diseased parts of the plant.
Propagation of Astragalus leucolobus S. Wats. ex M.E. Jones ssp. consectus (Sheldon) Abrams
Astragalus leucolobus S. Wats. ex M.E. Jones ssp. consectus (Sheldon) Abrams, also known as Contra Costa milk-vetch, is a rare legume species that is native to California. Due to its rarity, its propagation has become a crucial factor in its conservation.
Seed Propagation
The most common and effective technique for propagating Astragalus leucolobus S. Wats. ex M.E. Jones ssp. consectus (Sheldon) Abrams is through seed propagation. Seeds of the plant should be collected during the months of May and June as the pods begin to dry and open. These seeds should be stored in a cool and dry place until they are ready to be sown in the fall or early spring.
Before sowing, the seeds should be scarified to break their tough seed coat and allow water to penetrate. This can be done by rubbing them lightly with sandpaper or by soaking them in hot water for a few hours. Sowing should be done in well-draining soil and at a depth of ¼ - ½ inches. The soil should be kept moist until germination, which generally takes anywhere from 3-6 weeks.
Vegetative Propagation
Vegetative propagation of Astragalus leucolobus S. Wats. ex M.E. Jones ssp. consectus (Sheldon) Abrams is possible but not commonly used. It is done by using stem cuttings from healthy plants. These stem cuttings should be taken in the spring or early summer, when the plant is actively growing.
The cutting should be around 4-6 inches long and should be planted in a well-draining soil mix with good moisture retention. The soil should be kept moist until new growth starts to appear, indicating that the cutting has taken root. This usually takes around 4-6 weeks.
Overall, seed propagation remains the most effective and reliable method of propagating Astragalus leucolobus S. Wats. ex M.E. Jones ssp. consectus (Sheldon) Abrams.
