Origin
Lespedeza ×neglecta, also known as the bush clover, is a hybrid plant that originated from a cross between a Japanese and Chinese lespedeza species. This plant is native to East Asia and was first introduced to the United States in the 20th century as an ornamental plant.
Common Names
Bush clover is the most common name for Lespedeza ×neglecta, but it is also known by other names such as lespedeza, Japanese clover, and fall blooming clover.
Uses
Lespedeza ×neglecta is primarily used as an ornamental plant in landscaping and gardening. Its beautiful pink to purple flowers bloom in the late summer and early fall, providing a splash of color to gardens and landscapes. Additionally, bush clover helps in erosion control and soil improvement due to its nitrogen-fixing properties.
General Appearance
Lespedeza ×neglecta is a herbaceous perennial plant that grows up to 3 feet tall and 2-3 feet wide. Its leaves are green and trifoliate, with a serrated edge. The plant produces showy flowers in shades of pink, magenta, or purple, which are arranged in clusters along the stems. The flowers are followed by small, flat, brown seed pods. The plant has a delicate and graceful appearance, adding a touch of elegance to any landscape.
Light Requirements
Lespedeza ×neglecta grows best in areas with full sun exposure. It requires at least 6 hours of direct sunlight per day to thrive. Partial shading can affect its growth and may lead to reduced blooming.
Temperature Requirements
Lespedeza ×neglecta is a hardy plant that can withstand a wide range of temperatures. It can survive in USDA hardiness zones 4 to 9, withstanding temperatures as low as -20°F (-28.9°C) to as high as 100°F (37.8°C). However, it does not do well in areas with extreme temperature fluctuations.
Soil Requirements
Lespedeza ×neglecta prefers soils that are well-drained and loamy with a pH level ranging from 6.0 to 7.5. It can also grow in clay soils, but it is important to ensure that the soil is not waterlogged. The plant is not sensitive to soil texture but may not perform well in sandy soils with low nutrient content. Addition of organic matter can increase the fertility of the soil and promote optimal growth.
Cultivation of Lespedeza ×neglecta
Lespedeza ×neglecta thrives well in well-drained soil with a slightly acidic pH between 5.5 and 6.5. The plant prefers full sun to partial shade and grows best in areas with a mild climate. It is ideal for garden borders, naturalized areas, and wildlife gardens.
The plant grows up to 3 feet tall and 3 feet wide, therefore, it requires enough space to grow and thrive. When planting, space them at least 3 feet apart to prevent overcrowding.
Watering Needs
Lespedeza ×neglecta requires well-drained soil that is kept moist, especially during the growing season. Water the plant deeply once a week, or more frequently during hot and dry weather. Ensure the soil is not waterlogged as this can cause root rot and other damages to the plant.
During the winter season, water the plant sparingly as too much water can cause the roots to rot.
Fertilization
Lespedeza ×neglecta requires moderate fertilization to promote healthy growth and development. Apply a balanced fertilizer once a month during the growing season. Conduct soil test to determine the nutrients lacking in the soil and apply the appropriate fertilizer.
Avoid over-fertilization as this can lead to excessive growth, which can weaken the plant and make it more susceptible to disease and pest attacks.
Pruning
Lespedeza ×neglecta requires minimal pruning to maintain its shape and size. Prune the plant in early spring when the new growth begins to appear. Cut back the dead or damaged branches to promote healthy growth.
Avoid pruning the plant during the blooming season as this can reduce the number of flowers produced.
Propagation methods of Lespedeza ×neglecta Mackenzie & Bush (pro sp.)
Lespedeza ×neglecta Mackenzie & Bush (pro sp.), commonly known as bush clover, is a species of flowering plant that belongs to the pea family, Fabaceae. The plant is native to Asia and was first introduced to the United States in the late 1800s. The plant is primarily propagated through seeds and cuttings.
Seed Propagation
Propagation through seeds is the easiest and cheapest method of reproducing bush clover. Seeds are harvested from mature plants during the fall months when the seed pods have developed a dark brown or black color. After harvest, the seeds are air-dried before storing in a cool and dry place for future use.
Prior to sowing, the seeds must be treated with sulfuric acid for 5-10 minutes to increase germination rates. Once the seed coat is softened, the seeds can be planted directly in the ground or in containers filled with a well-draining potting mix. The seeds should be sown at a depth of 1/4 to 1/2 inches and should be kept moist but not wet to avoid damping-off.
Germination will occur within 2 to 3 weeks, and the seedlings can be transplanted to their permanent location after they have developed at least two sets of true leaves.
Cutting Propagation
Bush clover can also be propagated through cuttings taken from mature plants during the late summer months. The cuttings should be approximately 6-8 inches long and should be taken from the top of the plant. The cuttings should be removed with a sharp and clean tool and should be immediately placed in a container filled with water to prevent wilting.
After the cuttings have been removed from the plant, their bottom 1/2 to 1 inch should be dipped in rooting hormone powder to promote root growth. After dipping, the cuttings should be planted in a well-draining potting mix and kept in a shaded location with high humidity until new growth appears.
After approximately 6 weeks, the cuttings should have produced enough roots to be transplanted into their permanent location.
Disease Management
Lespedeza ×neglecta Mackenzie & Bush (pro sp.) is known to be susceptible to various diseases. Here are some common diseases and suggested ways to manage them:
- Crown Gall: This bacterial disease causes galls or tumors to form on the roots or stems of the plant. It can be managed by eliminating infected plants, disinfecting tools, and planting in well-draining soil.
- Leaf Spot: Caused by fungi, this disease produces circular spots on the leaves, which may turn yellow or brown. To manage it, remove infected leaves, avoid overhead watering, and apply fungicides as needed.
- Mosaic Virus: This viral disease causes mottling or streaking of leaves, and stunts growth. It can be managed by removing infected plants, controlling insect vectors, and avoiding planting in areas where the disease has been identified.
Pest Management
Lespedeza ×neglecta Mackenzie & Bush (pro sp.) is also vulnerable to pest attacks. Here are some common pests and suggested ways to manage them:
- Aphids: These small insects suck sap from the plant and secrete honeydew, which attracts ants and promotes fungal growth. To manage them, spray the plant with a strong stream of water or insecticidal soap.
- Japanese Beetles: These beetles feed on the foliage and flowers of the plant, causing significant damage. They can be managed by handpicking, using pheromone traps, or applying insecticides.
- Spider Mites: These tiny pests cause fine webs to appear on the plant, and can cause leaf discoloration and drop. To manage them, spray the plant with water and apply insecticidal soap or miticides.
