The flowers are funnel-shaped, white or pink in color, and are around two inches in diameter. The plant produces a white root that can reach a depth of up to 15 feet.Common Names
The Calystegia silvatica (Kit.) Griseb. ssp. fraterniflora (Mackenzie & Bush) Brummitt plant is widely known as Pacific false bindweed. This name is derived from its resemblance to common bindweed, which belongs to the same family. Other common names for this plant include woodland morning glory and silky bindweed.Uses
The Pacific false bindweed has several medicinal properties. It is known to have laxative and purgative effects and has been used to treat constipation and hemorrhoids. The root of the plant has been used to treat various ailments such as stomach cramps, menstrual pains, and skin inflammations. However, the plant is considered invasive and can cause problems for farmers and gardeners. It can grow rapidly and compete with other plants for sunlight, water, and nutrients. As such, it is important to control its spread and minimize its impact on native plants.Light Requirements
Calystegia silvatica (Kit.) Griseb. ssp. fraterniflora (Mackenzie & Bush) Brummitt prefers medium to full sunlight exposure for optimal growth and photosynthesis. The plant can tolerate partial shade, but excessive shade can lead to stunted growth and poor blooming.
Temperature Conditions
The plant is native to North America and typically grows well in USDA hardiness zones 4-8. It prefers cooler temperatures ranging from 60-75°F (15-24°C) during the day and 45-65°F (7-18°C) at night. The plant can tolerate freezing temperatures for short periods of time; however, extended periods of frost can damage the leaves and stems.
Soil Requirements
Calystegia silvatica (Kit.) Griseb. ssp. fraterniflora (Mackenzie & Bush) Brummitt prefers well-drained, fertile soil that is rich in organic matter. The plant can tolerate a wide range of soil pH levels but prefers slightly alkaline soil with a pH of 7-7.5. The plant can also tolerate drought conditions but prefers regular watering during prolonged dry spells.
Cultivation Methods
The Calystegia silvatica (Kit.) Griseb. ssp. fraterniflora (Mackenzie & Bush) Brummitt plant prefers well-drained soil and full sunlight. It can grow in a variety of soil types, including sandy, loamy, and clay soils. For best results, plant the Calystegia silvatica (Kit.) Griseb. ssp. fraterniflora (Mackenzie & Bush) Brummitt during the spring or fall when temperatures are mild.
Watering Needs
The Calystegia silvatica (Kit.) Griseb. ssp. fraterniflora (Mackenzie & Bush) Brummitt plant needs regular watering to thrive. Give it enough water to keep the soil consistently moist, but not wet. Be sure not to let the soil dry out completely either as the plant may not respond well to drought.
Fertilization
While Calystegia silvatica (Kit.) Griseb. ssp. fraterniflora (Mackenzie & Bush) Brummitt plants do not require frequent fertilization, you can give them a boost by fertilizing once or twice a year. Apply a slow-release fertilizer at the beginning of the growing season and again in mid-summer.
Pruning
Pruning Calystegia silvatica (Kit.) Griseb. ssp. fraterniflora (Mackenzie & Bush) Brummitt plants is not necessary, but removing spent flowers throughout the growing season will encourage new growth and help keep the plant looking tidy. Remove any dead or damaged foliage as soon as you notice it to prevent the spread of disease.
Propagation of Calystegia silvatica ssp. fraterniflora
Calystegia silvatica ssp. fraterniflora can be propagated through both seeds and vegetative cuttings.
Seeds
The seeds of Calystegia silvatica ssp. fraterniflora can be collected from the plant in the autumn and planted in the spring. To do this, wait until the seed pods turn brown and begin to split open, then collect the seeds. Store the seeds in a cool, dry place until planting in well-draining soil.
When planting the seed, prepare the soil by adding compost or other organic matter to improve drainage and fertility. Sow the seeds thinly, as they will require space to grow, and cover with a light layer of soil. Keep the soil moist but not waterlogged, and within three to four weeks, the seedlings should emerge.
Vegetative cuttings
Vegetative cuttings are a faster method of propagating Calystegia silvatica ssp. fraterniflora than seeds. Cuttings should be taken during the plant's active growing season in late spring or early summer.
To take cuttings, select healthy stems with at least four leaves. Cut the stem just below a leaf node and remove the lower leaves. Dip the cut end of the stem in rooting hormone, then plant it in a container filled with potting soil or directly into a well-drained garden bed. Keep the soil moist and the cutting in a shaded location until it begins to show new growth, at which point it can be gradually introduced to more sunlight.
Disease and Pest Management for Calystegia silvatica (Kit.) Griseb. ssp. fraterniflora (Mackenzie & Bush) Brummitt
Calystegia silvatica (Kit.) Griseb. ssp. fraterniflora (Mackenzie & Bush) Brummitt, commonly known as the woodland false bindweed, is a herbaceous perennial plant that can be found in forests, woodlands, meadows, and disturbed areas. While this plant is generally hardy, it is still susceptible to certain diseases and pests.
Common Diseases
One of the most common diseases that may affect Calystegia silvatica is powdery mildew. This fungus creates a white powdery coating on the leaves that can reduce photosynthesis and stunt plant growth. The best way to prevent this disease is to promote good air circulation by spacing out plants and removing any dead plant matter from the area.
Another common disease that the plant may develop is leaf spot. Leaf spot is caused by fungi or bacteria and can cause the plant's leaves to turn yellow, brown or develop small spots. The removal and destruction of infected leaves are essential to prevent the spread of disease.
Common Pests
Calystegia silvatica can also be affected by insects, including aphids and spider mites. If these pests are not controlled, they can cause significant damage to the plant. Aphids will suck the sap from the plant, depriving it of vital nutrients, while spider mites pierce the plant and suck the sap, leading to yellowed foliage and stunted growth.
Management Strategies
To control powdery mildew, one can use a fungicide on the affected plant and maintain proper air circulation and drainage; reduce nitrogen use and overhead irrigation to minimize the growth of the fungus. Leaf spot can be managed by pruning and removing any infected foliage and avoid the wetting of leaves while watering the plant.
Aphids and spider mites can be dealt with by introducing natural predators such as ladybugs or using insecticidal soap or oils. Regularly inspect the plants to catch and treat an infestation early.
Overall, it is essential to identify any problems as soon as possible and act quickly to prevent the spread of disease or pests affecting the Calystegia silvatica plant.
