Silkvine Periploca graeca
ABOUT
The plant known as the silk vine has a distinctive climbing habit, often using other plants or structures as support to spread its foliage. It possesses twining stems that help it to securely anchor and climb. On these stems, the leaves are arranged opposite one another, displaying an attractive dark green color. Each leaf is oval-shaped with pointed tips, giving them a sleek appearance. During its blooming season, the silk vine flourishes with clusters of small, star-shaped flowers. These flowers are a notable feature for their intricate structure and a blend of colors, usually cream or pale yellow, often with a purplish center that adds a touch of allure to the plant. As with many flowering vines, after the blossoming period, the plant will bear fruit. The silk vine produces slender, bean-like pods that contain numerous seeds. These pods have a silky interior lining, which has contributed to the common name of the plant. The fruits mature to a brown color and persist on the vine, adding to the visual interest even after the flowers have faded.

ToxicityTo humans
The plant known as silkvine (Periploca graeca) contains cardiac glycosides, which can be toxic to humans if ingested. These compounds can affect the heart muscle, leading to symptoms that may include nausea, vomiting, abdominal pain, diarrhea, and in severe cases, cardiac arrhythmias which can be potentially life-threatening. Care should be taken to avoid ingestion of any part of the silkvine plant due to its potential toxicity.
To pets
Silkvine (Periploca graeca) is also toxic to pets, including cats and dogs, due to the cardiac glycosides it contains. If a pet ingests any part of the silkvine plant, it may exhibit symptoms such as vomiting, diarrhea, abdominal pain, drooling, loss of appetite, and severe cardiac abnormalities, which include changes in heart rate and rhythm. These symptoms can be serious and warrant immediate veterinary attention to prevent potentially lethal consequences.

WaterThe Silk Vine should be watered thoroughly once the top inch of soil has dried out; this usually means watering roughly once a week during the growing season and reducing to once every two weeks or less during the dormant winter period. When watering, aim to provide enough water until it begins to run out of the drainage holes, which might be around 1 to 1.5 gallons for a medium-sized container. It's crucial not to let the Silk Vine sit in water, as this can lead to root rot, so always empty the saucer shortly after watering.
LightSilk Vine thrives best in bright, indirect light conditions. It should be placed in a location where it can receive plenty of light but protected from the direct harsh rays of the sun, especially during the peak hours of the afternoon. A spot near a south-facing window with some sort of light filtering, like sheer curtains, would be ideal for this plant.
TemperatureSilk Vine prefers temperatures between 60 and 85 degrees Fahrenheit. It can survive a minimum temperature down to about 50 degrees Fahrenheit; however, cold drafts and temperatures below this range should be avoided. The ideal temperature range promotes healthy growth and blooming.
PruningPruning Silk Vine is necessary to control its size, encourage bushier growth, and remove any dead or damaged stems. The best time to prune is in late winter or early spring before new growth starts. Pruning can be done annually, but light trimming can be done throughout the year as needed.
CleaningAs needed
SoilSilk vine thrives in a well-draining soil mix, with a pH level ranging from neutral to slightly alkaline (7.0-8.0). A mixture of loamy garden soil, peat, and sharp sand or perlite can create an ideal growing environment, promoting good drainage and aeration.
RepottingSilk vine requires repotting every two to three years to refresh the soil and to accommodate root growth. This consistent repotting schedule helps to maintain the plant's health and vigor.
Humidity & MistingSilk vine prefers moderate humidity levels but is relatively adaptable and can tolerate the drier air typical of indoor environments. However, ensuring some humidity can promote lush growth and a healthier plant.
Suitable locationsIndoor
Place silk vine in bright, indirect light and maintain moderate humidity.
Outdoor
Plant silk vine in sunlight or partial shade and well-draining soil.
Hardiness zone
Silk vine is suitable for USDA zones 7-10.
Life cyclePeriploca graeca, commonly known as silk vine, begins its life cycle as a seed which, when conditions are favorable, germinates and develops a root system and a shoot that grows toward the light. The plant then enters the vegetative stage, growing leaves and stems as it becomes a young vine, climbing on supports with the help of its twining stems. During the flowering stage, silk vine produces small, purplish-brown flowers usually in the late spring or early summer, which are pollinated by insects and can lead to the development of seed pods. Once pollinated, the flowers give way to slender, elongated seed pods containing seeds with silky tufts that are dispersed by wind. After reaching maturity and producing seeds, the plant enters a period of dormancy, especially in colder climates, where it may lose leaves or appear to die back until favorable growing conditions return. Silk vine can live for many years, going through the cycle of vegetative growth, flowering, and dormancy annually.
PropogationPropogation time
Spring-Early Summer
Propogation: The most popular method of propagation for Periploca graeca, commonly known as the Silk Vine, is through semi-hardwood cuttings. This is typically done in summer when the plant is actively growing. To propagate the Silk Vine, take semi-hardwood cuttings of about 4 to 6 inches (10 to 15 centimeters) in length, ensuring that each cutting has at least two to three leaf nodes. Strip the leaves from the bottom half of the cuttings to prevent excess moisture loss and possible rot. Dip the cut end into a rooting hormone to enhance root development, then plant the cuttings in a well-draining soil mix, ensuring that at least one leaf node is below the soil surface to facilitate root growth. The cuttings should be kept in a warm, humid environment with indirect light until they have rooted, which usually takes a few weeks. Once rooted, the cuttings can be potted up individually and gradually acclimatized to outdoor conditions if that is their intended final location.
