Sophora chrysophylla (Salisb.) Seem. var. glabrata (Gray) Chock. is a plant species belonging to the pea family (Fabaceae) and is native to California in the United States. The plant is known by various common names including golden bush, western mountain sophora, and wax leaf sophora.
Description of Sophora chrysophylla (Salisb.) Seem. var. glabrata (Gray) Chock.
The plant is a dense, evergreen, and woody shrub that can grow up to 15 feet (4.5 m) tall. Its leaves are bright green, waxy, and oval-shaped, measuring about 1-3 inches (2.5-7.6 cm) long. The foliage releases a pleasant fragrance when crushed.
The plant produces pea-like flowers that are yellow and grow in clusters from late spring to early summer (May to June). The fruit is a flat, elongated pod that contains several seeds.
Uses of Sophora chrysophylla (Salisb.) Seem. var. glabrata (Gray) Chock.
The plant has several ornamental and medicinal uses. It is commonly used in gardens as a hedge or border plant due to its attractive foliage and brightly-colored flowers. Additionally, the plant has been used traditionally by Native Americans for medicinal purposes such as curing rheumatism and tuberculosis. Studies also suggest that the plant has antibacterial and anti-inflammatory properties.
In modern times, the plant extract is used in some skincare products due to its protective and moisturizing qualities. However, caution must be taken as the plant is toxic when ingested and can cause skin irritation.
Light Requirements
The Sophora chrysophylla (Salisb.) Seem. var. glabrata (Gray) Chock plant requires full to partial sun exposure for optimal growth. It cannot tolerate extreme shade, but it can withstand a moderate amount of shade. This plant can thrive best in areas with an abundance of sunlight and well-drained soil that allows water to permeate easily.
Temperature Requirements
The Sophora chrysophylla (Salisb.) Seem. var. glabrata (Gray) Chock plant can grow well in a range of temperatures, but it thrives the most in warm and mild climates. It can adapt to temperatures ranging from 40-90 degrees Fahrenheit. This plant can tolerate occasional dry periods, but it cannot survive frost because it is sensitive to extremely low temperatures. Therefore, it needs protection during low winter temperatures.
Soil Requirements
The Sophora chrysophylla (Salisb.) Seem. var. glabrata (Gray) Chock plant requires well-drained soil for optimal growth. It can grow in various types of soils, but it grows best in neutral to mildly acidic soils with pH ranging from 6.0-7.5. The soil should contain moderate amounts of humus, sandy loam, and organic matter. The plant's root system is shallow, so the soil shouldn't be too compacted. Additionally, it is advisable to plant this species at higher elevations, as it prefers well-aerated clay loam soil.
Cultivation
The Sophora chrysophylla (Salisb.) Seem. var. glabrata (Gray) Chock, also known as the m?mane, is a fabled shrub endemic to Hawaii. It prefers to grow in well-drained soils at high elevations of 500 to 2,500 meters. Prior to planting seeds, the soil should be cleared of weeds or other vegetation. It is also helpful to add organic matter to the soil to improve drainage and nutrient content, as well as help support root growth.
Watering Needs
While m?mane is relatively drought-tolerant, it still requires consistent watering to thrive. During its first year of growth, it is essential to maintain moisture in the root zone by regular watering. M?mane should only be watered at the base of the plant, as overhead watering can cause fungal diseases. In areas where rainfall is scarce, it may be necessary to supplement watering to ensure the plant's adequate hydration.
Fertilization
M?mane does not require frequent fertilization. However, a slow-release, balanced fertilizer may be applied in the early spring to promote healthy growth. Over-fertilization should be avoided, as it may lead to excessive foliage growth at the expense of flower production, which in turn, produces fewer seeds.
Pruning
Pruning m?mane is critical to development since it requires light for growth and flowering. Precision pruning ensures that branches and leaves do not shade out the plant's central region. It is best done during the winter period when the plant is dormant. Pruning should be done to remove branches with disease, deadwood, and broken branches to improve plant health. To maintain its unique form, it should also be periodically cutting back new growth.
Propagation of Sophora chrysophylla (Salisb.) Seem. var. glabrata (Gray) Chock
Sophora chrysophylla (Salisb.) Seem. var. glabrata (Gray) Chock, also known as m?mane, is a shrub or small tree endemic to Hawaii. Here are some of the plant's propagation methods:
Seed Propagation
The easiest and most common method of propagating m?mane is through seeds. Collect the seeds from healthy, mature seed pods. Soak the seeds in water for 24 to 48 hours to soften the seed coat, and then plant them in well-draining soil. Be sure to provide them with enough sunlight and ample moisture until they germinate, which usually takes about 2 to 3 weeks.
Cuttings Propagation
Another way to propagate m?mane is through cuttings. Take 4- to 6-inch cuttings from the tips of the plant's branches during the growth season. Remove the lower leaves, leaving only the top two. Dip the cuttings' bottom ends in rooting hormone, and plant them in moist soil mixed with sand. Keep the soil humid by covering the cuttings with clear plastic, and place them in a warm and well-lit area that receives indirect sunlight. The cuttings will root in about 3 to 6 weeks.
Air Layering Propagation
Air layering can be done to propagate m?mane. Make a small cut halfway through a branch and cover it with damp sphagnum moss or peat moss. Then cover it with plastic wrap and seal the edges with tape. Wait for roots to form from the cut and then cut the branch below the new root bundle and plant it in well-draining soil.
M?mane's propagation methods depend on the grower's preference. Still, no matter which method is chosen, it is essential to select healthy plants and use sterile tools and techniques to avoid contamination.
Disease Management
Sophora chrysophylla (Salisb.) Seem. var. glabrata (Gray) Chock is generally resistant to many diseases. However, in certain weather conditions and poor soil conditions, the plant may become susceptible to fungal and bacterial diseases. The most common diseases that affect this plant include powdery mildew, root rot, and leaf spot. Powdery mildew can be identified by a white, powdery coating on the leaves, while root rot appears as black roots and wilting foliage. Leaf spot is characterized by black spots on the leaves.
To manage these diseases, it is important to ensure proper soil drainage and avoid overwatering. Additionally, removing and destroying infected plant material can help prevent the spread of disease. Fungicides and bactericides can also be used to treat specific diseases.
Pest Management
Sophora chrysophylla (Salisb.) Seem. var. glabrata (Gray) Chock may be prone to certain pests that can cause damage to the plant. The most common pests include spider mites, aphids, and scales. These pests can cause damage to the plant by sucking its juices and causing wilting, yellowing, and stunted growth.
To manage pest infestations, it is important to monitor the plant regularly for signs of pest activity. Infested leaves can be removed and destroyed. Natural predators such as ladybugs and lacewings can be introduced to control pest populations. Horticultural oils, insecticidal soaps, and neem oil can also be used to control pests.
