Origin
Ipomoea hanningtonii (Baker) Rendle, commonly known as Hannington's morning glory, is a species of flowering plant that belongs to the Convolvulaceae family. It is native to central and eastern Africa, specifically Ethiopia, Tanzania, and Kenya.
Common Names
Aside from Hannington's morning glory, the plant is also known by other common names such as African morning glory, bush morning glory, and Lilian's love.
Uses
Ipomoea hanningtonii is primarily cultivated as an ornamental plant valued for its showy flowers that bloom profusely throughout the year. In traditional African medicine, the plant is used as a cure for various ailments such as stomach ache, snake bites, and infertility. The seeds of the plant are sometimes used as a substitute for coffee.
General Appearance
Ipomoea hanningtonii is a sprawling, evergreen perennial plant that grows up to 6 meters long. The plant has a tuberous rootstock from which stems arise, and the leaves are heart-shaped with pointed tips and finely hairy. The flowers are large, funnel-shaped, and fragrant, measuring up to 12 cm in diameter, with five pale pink to white petals. They are held in clusters at the end of long, spiraled stems, and are followed by hard, rounded seed capsules containing numerous seeds.
Growth Conditions for Ipomoea hanningtonii
Ipomoea hanningtonii (Baker) Rendle, commonly known as the bushveld glory in South Africa, is a climbing vine that belongs to the family Convolvulaceae. This species is endemic to Tanzania and South Africa, where it grows in subtropical and tropical forests. It is known for its beautiful violet to purple flowers that bloom from summer to fall.
Light Requirements
Ipomoea hanningtonii prefers to grow in partially shaded areas, where it receives about 4-6 hours of direct sunlight per day. It can also tolerate full sunlight but will require frequent watering to prevent dehydration from intense light exposure. Too much shade can reduce flower production, while too much direct sunlight can damage the leaves and stems, leading to stunted growth and poor flowering.
Temperature Requirements
Ipomoea hanningtonii thrives in warm temperatures ranging from 20-30°C (68-86°F). It can withstand short periods of cold temperatures as low as 10°C (50°F), but extended exposure to frosty conditions can damage and kill the plant. In their natural habitat, this vine grows best during the rainy season, where temperatures are higher and humidity is relatively high.
Soil Requirements
Ipomoea hanningtonii prefers well-draining soils that are rich in organic matter. The pH of the soil should be neutral to slightly acidic, with a range of 6.0 to 7.5. This plant requires moderate watering, and the soil should be kept moist but not waterlogged as it can lead to root rot. Adding a layer of mulch can help to retain moisture and protect the roots from excessive heat.
In conclusion, by providing optimal light conditions, warm temperatures, and well-draining soils, Ipomoea hanningtonii can thrive in its natural habitat. These growth conditions can be replicated in gardens and greenhouses, where this vine can flourish and showcase its beautiful flowers.
Cultivation
I. hanningtonii is a tropical plant that requires warm temperatures and full sunlight. It thrives in well-drained soil with a neutral pH of 6.0 to 7.5. The plant needs a lot of space to grow, so make sure to plant it at least 2 feet apart.
Propagation can be done by dividing the roots, cuttings, or seeds. Sow the seeds in a well-draining potting mix under full sunlight and water moderately.
Watering Needs
Watering is crucial for I. hanningtonii's growth. The soil should be kept slightly moist but not saturated. Overwatering can cause root rot and kill the plant, while insufficient watering can result in stunted growth.
During hot weather, the plant may need frequent watering daily or every other day. During the colder months, water less frequently, allowing the soil to dry out to about an inch deep before watering again.
Fertilization
Regular fertilization is essential for I. hanningtonii's growth and flowering. Feed the plant every two to three weeks using a balanced fertilizer with equal parts of nitrogen, phosphorus, and potassium. Use a water-soluble liquid fertilizer and dilute it to half the strength recommended on the package.
During the growing season, apply a slow-release fertilizer a few times to keep the plant nourished. Avoid over-fertilizing, as it can lead to a buildup of salts in the soil, which can harm the plant's roots.
Pruning
I. hanningtonii needs regular pruning to maintain its shape and encourage bushier growth. The best time to prune is during the dormant season, which is typically in late winter or early spring.
Remove any dead, diseased, or damaged branches with a pair of pruning shears. Cut back any overgrown or leggy stems by at least a third of their length. This will stimulate the plant to produce new growth.
Regular pruning will also help prevent the plant from becoming invasive and overtaking other plants in the area.
Propagation of Ipomoea hanningtonii
Ipomoea hanningtonii (Baker) Rendle is a fast-growing and hardy plant that can be propagated in various ways. Here are some methods for propagating Ipomoea hanningtonii:
Seeds
One of the easiest and common ways to propagate the plant is through seeds. Seeds of Ipomoea hanningtonii can be collected from the plant's mature fruits, which are spherical capsules with four segments containing seeds. The seeds can be sown directly into the soil or in seed trays filled with well-drained soil. The ideal time for sowing seeds is in spring or early summer, just before the rainy season. The soil should be kept moist until the seedlings emerge, which usually takes about two to three weeks.
Cuttings
Another way to propagate Ipomoea hanningtonii is through stem cuttings. Select a healthy stem from the parent plant and cut it about 10-15 cm long. Remove the leaves from the lower half of the stem and dip the cut end in rooting hormone powder. Plant the stems in a pot filled with a well-draining soil mix and keep them in a warm, bright spot, with regular watering until new shoots appear.
Division
Ipomoea hanningtonii can also be propagated through division. This method involves digging up the parent plant and separating its roots into several sections. Each section should have a healthy root system and some stems attached. Replant the divisions in well-draining soil and keep the soil moist until they establish themselves in the new soil.
Grafting
Grafting Ipomoea hanningtonii is a less common method of propagation. It involves joining a stem or bud from the plant onto a related species of Ipomoea. This method requires skill and experience and is generally not recommended for amateur gardeners.
With the right propagation method, you can quickly and easily increase your stock of Ipomoea hanningtonii plants.
Disease and Pest Management for Ipomoea hanningtonii
Ipomoea hanningtonii (Baker) Rendle, commonly known as the white desert morning glory, is a beloved plant known for its unique beauty and resilience.

The fungal infections are caused by various fungi that spread through spores and can affect different parts of the plant. Leaves, stems, and flowers can all be affected by fungal infections. Symptoms of fungal infections include wilting, yellowing, and blackening of leaves, and premature death of flowers. Viruses spread through sap sucking insects such as aphids and whiteflies. Viral infections can cause stunted growth and yellowing of leaves.
Managing Diseases of Ipomoea hanningtonii
Preventing and managing fungal and viral infections in Ipomoea hanningtonii requires a multi-faceted approach that includes basic hygiene practices, planting resistant varieties, and using fungicides. To prevent the spread of fungal infections, it is essential to keep the plant clean and dry, avoid overhead watering, and remove any diseased parts of the plant. Planting disease-resistant varieties can also provide an added layer of protection. Furthermore, fungicides can be used as a preventive measure or as a treatment for existing infections.
Common Pests of Ipomoea hanningtonii
Whiteflies, spider mites, and aphids are some of the common pests that can infest Ipomoea hanningtonii. These pests suck the sap of the plant, leading to the yellowing and death of leaves.
Managing Pests of Ipomoea hanningtonii
The best strategy for managing pests in Ipomoea hanningtonii is to maintain the plant's health and adopt integrated pest management practices. Keeping the plant well-nourished and hydrated can make it less susceptible to pest infestations. Cultural controls, such as handpicking pests or using organic insecticides, can help eliminate them.
