Origin
Ipomoea holosericea, also known as the silky morning-glory, is a species of flowering plant in the family Convolvulaceae. It is native to southern Africa and found in countries such as Namibia, Botswana, Zimbabwe, and South Africa.
Common Names
Besides silky morning-glory, Ipomoea holosericea has other common names such as suurvy in Afrikaans, dikgerooi in Sesotho, and ikhankxwe in isiXhosa.
Uses
In traditional medicine, the roots of Ipomoea holosericea are used to treat various ailments such as stomach pains, diarrhea, and pneumonia. The plant's leaves and roots are also used to make a herbal tea that is believed to alleviate cold symptoms.
Ipomoea holosericea is also cultivated as a garden plant, where its pretty pink flowers and heart-shaped leaves are highly valued.
General Appearance
Ipomoea holosericea is a perennial plant that can grow up to two meters in height. Its leaves are heart-shaped, broad, and up to 10 cm long. The plant's stems are thin and twining, and the flowers are pink, funnel-shaped, and up to 5 cm in diameter. Ipomoea holosericea likes to grow in sandy soils, in full sun, and flowers from late winter to early summer.
Light Requirements
Ipomoea holosericea grows best in full sunlight. It can tolerate some shade but too much shade can hinder its growth and flowering. Therefore, it is recommended to plant it in a location that receives at least 6-8 hours of direct sunlight.
Temperature Requirements
This plant is native to sub-tropical and tropical regions and therefore requires warm temperatures to thrive. The ideal temperature range for its growth is between 21°C to 30°C. Temperatures below 10°C can damage the plant's leaves and stem, and frost will kill it rapidly.
Soil Requirements
The soil for Ipomoea holosericea needs to be well-draining but also retain moisture. Loam and sandy loam soils are the best for planting this species. Soil pH level should be between 5.5 to 7.5, if out of this range the plant may start to weaken. This plant is tolerant of some soil saturation, but it prefers soil to be slightly damp rather than swamp-like.
Cultivation of Ipomoea holosericea E.Mey. ex Choisy
Ipomoea holosericea E.Mey. ex Choisy, also known as the silvery morning glory, is a species of morning glory that is native to South Africa. Here are some cultivation methods to keep in mind:
- Ipomoea holosericea prefers well-draining soil that is rich in organic matter.
- It should be planted in an area that receives at least 6 hours of sunlight daily.
- The seeds should be planted in spring or early summer, after the danger of frost has passed.
- The seeds should be planted at a depth of ½ inch and spaced 12 inches apart.
- Seedlings should be thinned to 18 inches apart to allow enough space for growth.
Watering Needs
Proper watering is essential for the healthy growth of Ipomoea holosericea. Here are some tips for watering:
- The plant should be watered regularly, but not too frequently, as over-watering can cause root rot.
- It is best to water in the morning or evening, when the sun is not too strong.
- The soil should be allowed to dry out between watering, as this will encourage deep root growth.
- In times of drought, it is recommended to give the plant a deep watering once a week to help it survive.
Fertilization
Fertilization is a vital aspect of plant care that should not be overlooked. Here are some tips for fertilizing Ipomoea holosericea:
- A slow-release fertilizer should be added to the soil when planting, or during the growing season.
- Organic fertilizers, such as compost or manure, can also be used and are preferred by some gardeners.
- Fertilizer should be applied every 4 to 6 weeks during the growing season to promote healthy growth.
- Be sure to follow the instructions provided on the fertilizer packaging for best results.
Pruning
Pruning is an important aspect of caring for Ipomoea holosericea. Here are some tips for pruning:
- The plant can become quite invasive, so it is important to prune it regularly to prevent overgrowth.
- Remove any dead or damaged branches promptly to promote healthy growth.
- Prune the plant in late winter or early spring to control its size and shape.
- Pinch back the tips of the plant regularly to encourage bushier growth.
Propagation of Ipomoea holosericea E.Mey. ex Choisy
Ipomoea holosericea E.Mey. ex Choisy, commonly known as silky morning glory, is a beautiful flowering plant native to South Africa. It belongs to the family Convolvulaceae and the genus Ipomoea, which includes other popular plants such as sweet potato and morning glory. To propagate Ipomoea holosericea E.Mey. ex Choisy, gardeners have various options to choose from:
Propagation by seeds
Propagating Ipomoea holosericea E.Mey. ex Choisy by seeds is an easy and practical method. Collect seeds from mature seed pods when they turn brown and brittle. Sow the seeds in well-draining soil in a sunny location, burying them about 1-2 cm beneath the soil surface. Keep the soil moist, but not soggy, and wait for the seeds to germinate, which usually occurs within 2-3 weeks.
Propagation by cuttings
Ipomoea holosericea E.Mey. ex Choisy can also be propagated by stem cuttings. Take a 10-15 cm cutting from a healthy plant with a sharp and sterilized knife. Remove the leaves from the bottom of the stem, leaving only two or three leaves at the top. Dip the cutting in rooting hormone and plant it in moist soil, preferably a sand and peat mixture. Cover the cutting with a plastic bag to create a humid environment and place it in a well-lit area, avoiding direct sunlight. Water the cutting regularly and, after one month, check for rootedness by tugging gently on the stem. If the stem resists a little, the cutting has successfully rooted and can be removed from the plastic bag.
Propagation by division
Lastly, Ipomoea holosericea E.Mey. ex Choisy can be propagated by dividing the plant. When the plant is mature and has a dense root system, carefully dig it out from the soil and separate its root clumps into several smaller plants. Make sure each plant has a healthy root system and replant them in their new locations, watering them thoroughly.

Common Diseases
Like all plants, Ipomoea holosericea is vulnerable to certain diseases that can affect its growth and health. Some of the most common diseases that affect this plant include:
- Leaf spot: This fungal disease causes circular or irregular spots on the leaves. It can be treated with fungicides and by removing infected leaves.
- Powdery mildew: This fungal disease looks like a white powdery coating on the leaves. It can be treated with fungicides and by reducing humidity around the plant.

Pest Management
Ipomoea holosericea is also vulnerable to pest infestations that can cause significant damage. Some of the most common pests that affect this plant include:
- Aphids: These small, soft-bodied insects suck sap from the leaves and stems, causing wilting and stunted growth. They can be treated with insecticidal soap or by attracting natural predators like ladybugs.
- Spider mites: These tiny pests are barely visible to the naked eye and spin webs on the underside of leaves. They can be treated with insecticidal soap or by spraying the plant with water to dislodge them.
- Thrips: These tiny insects cause leaves to turn yellow or brown and stunt growth. They can be treated with neem oil or insecticidal soap.
To prevent pest infestations, it's important to maintain good plant hygiene, avoid overcrowding, and remove any infested leaves or plants promptly.
By taking preventive measures and promptly treating any diseases or pest infestations, you can keep your Ipomoea holosericea healthy and thriving.
