The flowers of the plant are small, yellow-green in color, and grow in clusters. The fruit of the plant is a greenish-yellow, round-shaped berry that is about 1 to 2 centimeters in diameter, and contains black seeds.

The leaves are used as a remedy for coughs, fever, and headaches, while the fruit is believed to have anti-inflammatory properties. In Malaysia, the fruit is also used to treat diarrhea and dysentery. Additionally, the wood of the plant is used in construction and furniture making.
Light Requirements
Uvaria connivens Benth. thrives in bright, filtered light. Too much direct light can scorch its leaves and hinder growth. It is best to provide partial shade or indirect sunlight for optimal growth of the plant.
Temperature Requirements
The ideal temperature range for Uvaria connivens Benth. is between 20-30° Celsius. Temperatures below 15° Celsius can severely damage the plant, while temperatures above 35° Celsius can cause the leaves to wilt and dry out.
Soil Requirements
Uvaria connivens Benth. requires well-draining soil with a pH range of 5.5-6.5. It prefers a mix of organic and inorganic materials. A soil mix consisting of sand, peat moss, and perlite in equal parts works well for these plants.
Cultivation Methods
The Uvaria connivens Benth. plant is native to tropical areas and needs warm temperatures to grow healthily. It can be grown both indoors and outdoors as long as it receives the required amount of sunlight.
For outdoor cultivation, plant the U. connivens in well-draining soil in a location that receives partial to full sun. The plant needs adequate spacing, and it's advisable to plant it in a location sheltered from strong winds. Indoor cultivation requires bright, filtered light and a humid environment.
Watering Needs
The U. connivens plant thrives in well-draining soil that's kept moist; however, it's important to avoid overwatering. Water the plant when the soil feels dry to the touch, and ensure adequate drainage to prevent waterlogging. During the dry season, water more frequently to prevent wilting.
Fertilization
U. connivens benefits from regular fertilization, especially during its growth period. Fertilize the plant with a balanced fertilizer, every two weeks, to encourage growth and development. Use a slightly diluted solution if the plant is still young. Stop fertilizing in the winter when the plant goes into dormancy.
Pruning
Prune U. connivens during the fall and winter dormant period while removing any dead, diseased, or damaged plant parts. This pruning encourages the plant's healthy growth and flowering. To avoid damaging the plant, use clean pruning shears when cutting off the stems, and avoid cutting excessively.
Propagation of Uvaria connivens Benth.
Uvaria connivens Benth., commonly known as the Sleepy Head plant, is a tropical plant species. It is a woody climber with attractive foliage and fragrant flowers. The propagation of this plant can be done either through seeds or vegetative propagation.
Propagation through seeds
Propagation through seeds is the easiest way to reproduce Uvaria connivens Benth. The seeds should be collected from a mature plant, and the best time for collecting seeds is during the dry season. The collected seeds should be washed and then dried under the sun for a few days before sowing.
The seeds should be sown in a well-drained potting mix, and the pot should be kept moist. The ideal temperature for seed germination is between 25-30°C. The seeds will take around 2-4 weeks to germinate. Once they have germinated, the seedlings can be transplanted to a larger container, or to the ground, after they have developed sufficient roots.
Vegetative propagation
Vegetative propagation of Uvaria connivens Benth. can be done using stem cuttings. Take a 10-15 cm long stem cutting from a healthy plant. The cutting should have at least two nodes. Remove all leaves except the top 2-3 leaves. Dip the cut end of the stem cutting in rooting hormone powder and insert it into a well-draining potting mix. Water the cutting thoroughly and place it in a shaded area.
The cutting should be kept moist and out of direct sunlight. After a few weeks, the cutting will start producing new leaves, which is an indication that the roots have developed. Once the roots have developed sufficiently, the plant can be transplanted to a larger pot or to the ground.
Propagation through air layering is also possible, but it is a complicated process and requires more skill and care.
Disease and Pest Management for Uvaria connivens Benth.
Uvaria connivens Benth., commonly known as "Benth. Uvaria," is a plant species that is native to tropical regions of Asia and Africa. While it is generally resistant to diseases and pests, there are a few issues that can affect its growth and cause problems. Here are some common diseases and pests that might affect the plant and suggested ways to manage them.
Common Diseases
One of the most common diseases that affect Uvaria connivens is powdery mildew, a fungal disease that can appear as a white or grayish powdery coating on the leaves. This disease can stunt the growth of the plant and can be especially problematic if left unmanaged.
To manage powdery mildew, it is recommended to prune affected leaves and branches and encourage good air circulation around the plant. Additionally, applying a fungicidal spray can help prevent further spread of the disease.
Another disease that can impact Uvaria connivens is root rot, which is typically caused by overwatering or poorly-draining soil. This disease can cause the plant's roots to decay, resulting in wilting, yellowing leaves and stunted growth.
To manage root rot, it is important to avoid overwatering and ensure that the plant is in well-draining soil. Additionally, treating the plant's roots with a fungicidal spray can help prevent the disease from spreading.
Common Pests
Uvaria connivens is generally not susceptible to serious pest infestations, however, there are a few pests that can still pose a problem. Thrips and spider mites are two common pests that can affect the plant, causing discoloration and damage to the leaves.
To manage thrips and spider mites, removing any visibly affected leaves and using a pesticide spray targeted towards the specific pest can help reduce their populations. It is important to use the pesticide carefully and according to the instructions on the label to avoid harming the plant or yourself.
Overall, by maintaining good plant care and promptly addressing any signs of disease or pest infestations, Uvaria connivens can thrive and remain healthy.
