Description
Convolvulus subacaulis, also known as low bindweed, is a perennial plant that belongs to the morning glory family, Convolvulaceae. It is native to western North America, particularly in the states of California, Nevada, Arizona, and Utah.
General Appearance
The plant grows up to 25-50 cm tall and forms a basal rosette with numerous stems that grow along the ground. The stems and leaves are covered with hairy grey-green foliage. The flowers are funnel-shaped and bloom in clusters at the end of the stems. The flowers are typically pink or white in color, with darker pink stripes at the base of each petal. The plant blooms from spring to fall.
Common Names
Aside from low bindweed, Convolvulus subacaulis is also commonly called short-stemmed morning glory, dwarf morning glory, and pintantillo in Spanish.
Uses
Convolvulus subacaulis is primarily used as an ornamental plant in gardens and landscapes due to its beautiful, delicate flowers. It is also grown as a ground cover due to its spreading habit. Additionally, this plant is known to attract bees and other pollinators, making it a beneficial addition to any garden. In traditional herbal medicine, the plant is used as a diuretic and laxative. However, further research is needed to confirm its medicinal properties and safety for human consumption.
Growth conditions for Convolvulus subacaulis
Convolvulus subacaulis (Hook. & Arn.) Greene is a small, perennial herb that is native to western North America. The plant is a member of the morning glory family and typically grows to a height of around 10-20 cm.
Light requirements
Convolvulus subacaulis typically grows best in full sun. The plant requires a minimum of 6 hours of direct sunlight per day to thrive. In areas with hot summers, the plant benefits from some light shade during the hottest parts of the day.
Temperature requirements
Convolvulus subacaulis is adapted to a range of temperatures, though it prefers a relatively mild climate. The plant grows well in temperatures between 15°C and 27°C, with nighttime temperatures between 7°C and 16°C. It can tolerate occasional frosts, but extended periods of freezing temperatures can be detrimental to the plant's growth and survival.
Soil requirements
Convolvulus subacaulis grows best in well-drained soils that are rich in organic matter. The plant prefers slightly acidic to neutral soils with a pH between 6.0 and 7.0. Sandy loam soils with good drainage are ideal. The plant can tolerate some saline soils, but it does not do well in heavy clay or waterlogged soils.
Cultivation Methods
Convolvulus subacaulis, commonly known as low bindweed, is a perennial herb native to western North America. This plant prefers well-drained soil with moderate moisture and full sunlight to partial shade. It is adaptable to various soil types, including sandy, loamy, and rocky soils. The ideal temperature range for its growth is between 55 and 85°F (13-29°C).
You can propagate Convolvulus subacaulis by seeds or cuttings. Sow the seeds in early spring or fall, and keep them moist until they germinate. For cuttings, take 3-to-4-inch stem sections in early summer, dip them in rooting hormone powder, and plant them in a well-draining potting medium.
Watering Needs
Convolvulus subacaulis requires moderate watering, especially during its growing season. Water the plant when the top 1 inch of soil is dry. Avoid overwatering, as it may cause root rot and yellowing of leaves. In the dormant season, reduce watering to once every 2-3 weeks.
Fertilization
Convolvulus subacaulis benefits from fertilization, especially in poor soil conditions. Apply a balanced fertilizer, such as 10-10-10, in early spring when the new growth appears. Repeat the fertilization process every 6-8 weeks until the fall season. Always follow the package instructions for the recommended dosage.
Pruning
Convolvulus subacaulis requires light pruning to maintain a compact shape and promote bushier growth. Prune the plant in late winter or early spring before new growth appears. Remove the dead, damaged, or diseased branches by cutting them back to their base. You can also pinch back the tips of young shoots to encourage branching. Avoid pruning in the summer or fall, as it may reduce the plant's ability to survive the winter season.
Propagation of Convolvulus subacaulis
Convolvulus subacaulis (Hook. & Arn.) Greene is a low-growing perennial plant that is commonly known as the stemless bindweed. The plant is native to the southwestern United States and Mexico and belongs to the family Convolvulaceae. The stemless bindweed produces tubular flowers that are trumpet-shaped and range in color from pink to purple. The plant is commonly propagated using seeds and cuttings.
Propagation by Seeds
The most common method of propagating Convolvulus subacaulis is by using seeds. Seeds can be collected from mature plants and stored in a dry and cool place until they are ready to be sown. The seeds should be thinly sown in well-draining soil and covered lightly with soil. The soil should be kept moist until the seeds germinate, which typically takes between 1 and 3 weeks. Once the seedlings have grown large enough, they can be transplanted into their permanent location.
Propagation by Cuttings
Convolvulus subacaulis can also be propagated by using cuttings. Cuttings should be taken from mature plants during the growing season. The cuttings should be approximately 4 to 6 inches long and should be taken from healthy and disease-free plants. The cuttings should be stripped of their lower leaves and planted in a well-draining soil mix. The cuttings should be kept moist and in a shaded area until they have developed roots, which typically takes between 2 and 4 weeks. Once the cuttings have developed roots, they can be transplanted into their permanent location.
Disease and Pest Management for Convolvulus subacaulis
Convolvulus subacaulis, commonly known as California bindweed, is a hardy plant that can tolerate a range of growing conditions. However, like all plants, it is still susceptible to disease and pest infestations that can affect its growth and overall health. Here are some of the most common diseases and pests that can affect Convolvulus subacaulis, and suggestions for managing them:
Diseases
Root Rot: Root rot is a fungal disease that can be caused by overwatering or poorly drained soil. Symptoms include wilting, yellowing leaves, and stunted growth. To manage root rot, it is important to improve soil drainage by adding organic matter or perlite to the soil. Avoid overwatering and remove any affected plants promptly.
Mildew: Powdery mildew is a fungal disease that can affect the leaves of Convolvulus subacaulis. It appears as a white, powdery substance on the leaves and can cause them to become distorted. To manage mildew, try to maintain good air circulation around the plant and avoid overhead watering. Neem oil or other fungicides may also be necessary to treat severe infections.
Pests
Mites: Spider mites are a common pest that can infest Convolvulus subacaulis, causing leaves to turn yellow and develop small, web-like structures. To manage mites, rinse the plants with water frequently to remove them and prevent infestations. Insecticidal soap or neem oil may also be used for severe infestations.
Thrips: Thrips are small, winged insects that can cause significant damage to Convolvulus subacaulis. They can feed on the flowers and leaves, causing them to become distorted and discolored. To manage thrips, try using yellow sticky traps to catch adult insects. Insecticidal soap, neem oil, and other insecticides may also be necessary to control severe infestations.
Slugs and Snails: Slugs and snails can be a problem for Convolvulus subacaulis, especially in damp or humid conditions. They can eat holes in the leaves and damage the stem, causing the plant to wilt or die. To manage slugs and snails, try using copper tape around the plant base to create a barrier. Beer traps or other baits may also be used to lure and kill these pests.
By monitoring your Convolvulus subacaulis regularly and taking appropriate measures to manage disease and pest infestations, you can ensure that your plants remain healthy and vibrant throughout the growing season.
