Overview
Cissus puberula C.A.Sm. is a species of flowering plant in the grape family, Vitaceae, that is native to northern South America in countries such as Venezuela, Colombia, and Ecuador. It is also known by other common names such as bella sombra, vid negra, and silverleaf grape. The plant is known for its various uses, including medicinal and ornamental purposes.
Appearance
Cissus puberula is a climbing vine that can reach up to 7 meters in height. Its leaves are alternate, simple, and heart-shaped, measuring about 10 centimeters in length. The plant's stems are hairy, while its fruit is a small berry that turns from green to black as it matures. Cissus puberula's most distinctive feature is its silvery-white pubescence, which covers the undersides of its leaves, giving the plant a beautiful appearance.
Medicinal Uses
Cissus puberula has been used traditionally in South America as a medicinal herb, treating various health conditions such as wounds, diarrhea, and fever. Recent scientific studies have shown that extracts from the plant have antioxidant and anti-inflammatory properties, making it a potential treatment for conditions such as arthritis and other inflammatory diseases.
Ornamental Uses
Cissus puberula is a popular ornamental plant due to its attractive appearance brought about by its silvery-white pubescence. The plant is commonly used in landscaping, adding aesthetic value to gardens and homes. Its climbing nature also makes it ideal for covering trellises and walls, creating a beautiful green wall.
Light Requirements
Cissus puberula is a plant that requires bright but indirect sunlight in order to thrive. Placing the plant in direct sunlight can cause the leaves to sunburn and turn yellow. Ideally, this plant should be placed near a window that faces east or west, or under a shaded area outside where it can still receive bright light without being directly in the sun.
Temperature Requirements
This plant is native to tropical regions, therefore it is best grown in warm and humid conditions. Ideally, the temperature should be around 60-75°F during the day and no lower than 55°F at night. This plant is not frost-tolerant and should be kept away from cold drafts from windows or doors.
Soil Requirements
Cissus puberula requires well-draining soil that is rich in organic matter. A soil mix that contains coarse sand, perlite, and peat moss is ideal for this plant. The soil pH should be between 6.0 – 7.0. This plant does not like waterlogged soil, and its roots can rot if the soil holds too much moisture. It is, therefore, important to allow the soil to dry slightly between waterings.
Cultivation of Cissus puberula C.A.Sm.
Cissus puberula C.A.Sm. can be grown both indoors and outdoors, but it requires warm temperatures to thrive. It prefers well-draining soil with a pH range of 6.0-7.5 and partial shade. If grown indoors, it needs bright and indirect light. It is advisable to propagate the plant through stem cuttings or layering in the spring or fall.
Watering needs
Cissus puberula C.A.Sm. does not require frequent watering, and overwatering can lead to root rot. It is advisable to water the plant liberally when the soil is dry to the touch, making sure that the water drains properly. In summer, when temperatures are high, the plant may need more frequent watering.
Fertilization
Feeding Cissus puberula C.A.Sm. is not a mandatory requirement; however, the plant benefits from occasional fertilization during the growing season. A balanced liquid fertilizer with a 20-20-20 ratio should be applied every four weeks to encourage strong growth and maintain its health.
Pruning
Pruning promotes bushy growth and enhances the plant's aesthetic appeal. It is advisable to prune Cissus puberula C.A.Sm. back in the late winter or early spring, just before the growing season. Prune any dead, yellow, or diseased foliage, as well as any leggy or straggly vines. Pinching back stem tips promotes bushy growth and keeps the plant from becoming too leggy.
Propagation of Cissus puberula C.A.Sm.
Cissus puberula C.A.Sm., nicknamed the "Velvet Grape", is a popular climbing plant species that is native to Oaxaca, a state in southern Mexico. It is a semi-succulent plant that is characterized by velvety leaves and smooth stems that are green when young and turn woody and brown as they mature.
Methods of Propagation
Cissus puberula C.A.Sm. can be propagated through seeds and stem cuttings. However, stem cuttings are the most effective and popular method of propagating the plant as they have higher success rates than seeds.
Propagation through Stem Cuttings
To propagate Cissus puberula C.A.Sm. through stem cuttings, follow these simple steps:
- Take a stem cutting that is at least 10 cm long and has at least two nodes. Make sure that the cutting is taken from a healthy and mature plant.
- Remove all the leaves except for the top two leaves of the cutting. This will reduce water loss and encourage root formation.
- Optional: Dip the bottom end of the cutting in rooting hormone powder to encourage root formation. While this is not necessary, it can increase the chance of success.
- Plant the cutting in a well-draining potting mix or soil. Make sure that the soil is moist and has good drainage.
- Place the pot in a warm and bright location, but away from direct sunlight. Maintain the soil moisture and water the cutting as necessary.
- Roots should start forming within a few weeks. Once the roots are well-established, which can take 2-3 months, the cutting can be transplanted to a bigger pot or directly into the ground.
Propagation through Seeds
Propagation through seeds is also possible but is not a popular method as it takes longer and has a lower success rate.
- Harvest the seeds from a mature and healthy Cissus puberula C.A.Sm. plant in the fall or winter when the berries are ripe and have turned purple.
- Clean the seeds and soak them in warm water for 12-24 hours to soften the outer seed coats.
- Plant the seeds in a well-draining potting mix or soil, preferably in a seedling tray.
- Place the tray in a warm and bright location but away from direct sunlight. Maintain soil moisture and water as necessary.
- The seeds should germinate within 2-3 weeks. Once the seedlings are big enough to handle, they can be transplanted to individual pots or directly into the ground.

Common Diseases
One of the common diseases that can affect Cissus puberula C.A.Sm. is powdery mildew. Powdery mildew is a fungal disease that appears as white or gray powdery growth on the leaves, stems, and flowers of the plant. This disease can cause the plant to weaken, and it may eventually die if left unmanaged.
To manage powdery mildew, it is essential to maintain good air circulation around the plant. This can be achieved by pruning the plant regularly and avoiding overhead watering. Fungicidal sprays can also be used to manage the disease.
Common Pests
Cissus puberula C.A.Sm. can also be affected by pests such as spider mites. Spider mites are tiny insects that suck the sap from the leaves of the plant, causing the leaves to appear yellow and stippled. In severe cases, the leaves may fall off, and the plant may die.
To manage spider mites, it is important to maintain good hygiene around the plant. Dead leaves and debris should be removed, and the plant should be watered regularly. Insecticidal soap or horticultural oil can also be used to manage the pest.
Another pest that can affect Cissus puberula C.A.Sm. is mealybugs. Mealybugs are white, cotton-like insects that feed on the sap of the plant. They can cause the leaves to turn yellow and wilt, and they may also transmit plant viruses.
To manage mealybugs, it is essential to inspect the plant regularly and remove any visible insects. Insecticidal soap or horticultural oil can also be used to manage the pest.
By maintaining good plant hygiene and using appropriate treatments, it is possible to manage both diseases and pests that can affect Cissus puberula C.A.Sm. With proper care, this plant can thrive and provide years of enjoyment for gardeners and plant enthusiasts.
