Common names for Convolvulus binghamiae Greene
Aside from Bingham's bindweed, Convolvulus binghamiae is also commonly referred to as Sierra bindweed and Sierra morning glory.
Uses of Convolvulus binghamiae Greene
While Convolvulus binghamiae is not typically used for medicinal or culinary purposes, it is a popular ornamental plant among gardeners due to its striking appearance. The plant's large, showy flowers feature deep blue petals surrounding a white center, and bloom from late spring to mid-summer. As a perennial plant, Convolvulus binghamiae can reappear year after year, making it a favorite among gardeners who prefer low-maintenance plants that bring color and beauty to their gardens.
Appearance of Convolvulus binghamiae Greene
Convolvulus binghamiae is a creeping or trailing plant, with stems that can grow up to 3 feet long. Its leaves are alternate, simple, and elongated, measuring up to 2 inches in length. The plant's flowers grow on long, thin stems that arise from the leaf axils, and feature five deep blue petals that measure up to 1 inch in length. The flowers are typically funnel-shaped, with a white center that is surrounded by a yellow throat. Convolvulus binghamiae produces a large number of seeds, which are spread by the wind and can easily propagate the plant in its native habitat.
Light Requirements
Convolvulus binghamiae Greene is a sun-loving plant and requires full sun to really thrive. It prefers at least 6 hours of direct sunlight per day, so it is best to place it in an area where it can receive this amount of sunlight.
Temperature Requirements
This plant is well-adapted to a warm and dry climate, so it typically grows in areas where the temperature is between 60 and 90 degrees Fahrenheit. It can tolerate short periods of extreme heat, but prolonged exposure to temperatures outside of its ideal range can be harmful to the plant.
Soil Requirements
The soil that Convolvulus binghamiae Greene needs to successfully grow must be well-drained and nutrient-rich. It prefers soil that is slightly acidic, with a pH range of 6.0 to 7.0. The plant can tolerate some drought but performs best when the soil is kept evenly moist. It is important to avoid over-watering, as this can cause root rot.
Cultivation
Convolvulus binghamiae Greene is a low-growing and mat-forming plant that is best suited for cultivating in USDA zones 8-11. It thrives in well-draining soils, especially those that are sandy or gritty. While it can grow in partial shade, it prefers full sun exposure for optimal growth and flowering.
Watering Needs
Consistent moisture is essential for the healthy growth of Convolvulus binghamiae Greene. It is recommended to water this plant regularly, especially during the hot and dry summer months. However, excess watering should be avoided as it can cause root rot.
Fertilization
When cultivating Convolvulus binghamiae Greene, it is vital to provide the plant with sufficient nutrients. Fertilizer should be added during the active growing season, which is typically in the spring and summer months. A slow-release fertilizer applied every six to eight weeks is ideal for this plant.
Pruning
Pruning is an essential aspect of Convolvulus binghamiae Greene cultivation. Regular pruning can help maintain the plant's shape and promote healthy growth. It is recommended to prune the plant after flowering, cutting back the stems to encourage bushier growth. Additionally, the plant can be shaped by pinching the tips of the growing stems, which will encourage branching.
Propagation of Convolvulus binghamiae Greene
Convolvulus binghamiae Greene, commonly known as Bingham's bindweed, is a perennial plant species that belongs to the Morning Glory family. The plant is native to California, where it prefers to grow in gravelly or sandy soils, well-drained slopes, and rock crevices. Propagation of Convolvulus binghamiae can be done through several methods, which are discussed below:
Seed Propagation
The easiest and most common way to propagate Convolvulus binghamiae is through seed propagation. The seedlings can be obtained from the ripe seeds that are collected in late summer or early fall. The seeds should be sown in prepared soil in the fall or early spring. Before sowing, the seeds should be soaked in water for 24 hours to increase the germination rate. The seedlings will emerge within two weeks, and they should be thinned to one plant per pot once they have two true leaves. The seedlings should be kept in a bright but cool location until they are ready to transplant outdoors.
Cuttings Propagation
Another propagation method for Convolvulus binghamiae is through stem cuttings. Cuttings can be taken in early spring when the new growth starts to appear. The cuttings should be six inches long and should be taken from the non-flowering stems. The cuttings should be dipped in rooting hormone and then planted in a well-draining potting mix. The pot should be covered with a plastic bag to keep the cutting moist and warm. The cuttings will root within a few weeks, and they can be transplanted outdoors once they are well-established.
Division Propagation
Division propagation is a method of propagating Convolvulus binghamiae by dividing the established plant into smaller sections. The best time to divide the plant is in early spring before the new growth starts to appear. The plant should be carefully dug up, and the root ball should be divided into several sections using a sharp and sterile knife. Each section should have at least one healthy shoot and roots. The divided sections should be replanted in prepared soil, and they should be kept moist until they are well-established.
Overall, Convolvulus binghamiae can be propagated through seed propagation, cuttings propagation, or division propagation. The choice of propagation method depends on the availability of the plant material and the grower's preference.
Disease and Pest Management for Convolvulus binghamiae Greene
Convolvulus binghamiae Greene, also known as Bingham's bindweed, is a drought-tolerant plant that is native to the Western United States. While this plant is generally hardy and disease-resistant, there are a few common diseases and pests that can affect its growth.
Common Diseases
One of the common diseases that affect Convolvulus binghamiae is root rot. Root rot is a fungal disease that affects the roots of the plant, causing them to rot and die. This disease is caused by overwatering, and it can be prevented by ensuring that the plant is not overwatered. Additionally, a well-draining soil can help prevent root rot by allowing excess water to drain away from the roots.
Another common disease that affects Convolvulus binghamiae is leaf spot. Leaf spot is a fungal disease that causes brown or black spots to form on the leaves of the plant. This disease is typically caused by wet conditions, and it can be prevented by ensuring that the leaves of the plant are kept dry and by providing adequate spacing between plants to allow for proper air circulation.
Common Pests
One of the most common pests that affect Convolvulus binghamiae is the spider mite. Spider mites are small, sap-sucking pests that can cause severe damage to the plant. They are typically found on the undersides of leaves, and they can be identified by the fine webbing that they produce. Spider mites can be managed by regularly inspecting the plant and removing any infested leaves. Additionally, a strong blast of water can help dislodge the mites from the plant.
Another common pest that affects Convolvulus binghamiae is the caterpillar. Caterpillars are the larval stage of moths and butterflies, and they can cause significant damage to the plant by eating its leaves and stems. Handpicking the caterpillars and removing them from the plant is the most effective way to manage this pest.
Conclusion
Overall, Convolvulus binghamiae is a hardy plant that is resistant to diseases and pests. However, it is important to be vigilant and regularly inspect the plant to ensure that any issues are identified and addressed promptly. By following these simple disease and pest management techniques, gardeners can help ensure the long-term health and beauty of their Convolvulus binghamiae plants.
