This plant thrives in temperatures between 18-25°C (64-77°F), making it ideal for indoor cultivation. It is important to keep the plant away from cold drafts, as exposure to temperatures below 15°C (59°F) can damage or kill the plant.
Soil Requirements
Clerodendrum violaceum Gürke subsp. kigeziense Verdc. prefers well-draining soil that retains moisture but does not become waterlogged. A mixture of potting soil, perlite, and peat moss can provide the ideal growing medium. The soil should be kept consistently moist, but do not allow the plant to sit in standing water. Fertilize the plant with a balanced fertilizer every two weeks during the growing season, from spring to fall, to encourage healthy growth and blooming.
Cultivation Methods for Clerodendrum violaceum Gürke subsp. kigeziense Verdc.
Clerodendrum violaceum Gürke subsp. kigeziense Verdc. is a delicate plant that requires a little extra care to thrive. When cultivating this plant, ensure you place it in a location with partial shade to protect it from direct sunlight, which can be harmful to its growth. The plant grows well in well-drained soils rich in organic matter. Ensure to plant it in a deep hole filled with fertile soil.
Watering Needs for Clerodendrum violaceum Gürke subsp. kigeziense Verdc.
Clerodendrum violaceum Gürke subsp. kigeziense Verdc. requires moderate watering to prevent the soil from drying out while avoiding waterlogging. It is best to maintain the soil's moisture level, which can be achieved by checking the soil's moisture level using a moisture meter or placing a finger in the soil. Water the plant thoroughly once the surface soil feels dry to the touch.
Fertilization for Clerodendrum violaceum Gürke subsp. kigeziense Verdc.
Application of fertilizer in the planting hole can help improve the plant's growth rate. Use a slow-release fertilizer after planting and fertilize in the next spring. Excessive fertilization can lead to rapid growth of foliage at the expense of flowers.
Pruning Clerodendrum violaceum Gürke subsp. kigeziense Verdc.
Pruning is necessary to maintain Clerodendrum violaceum Gürke subsp. kigeziense Verdc. and control its growth. Prune the plant in spring just before new growth appears.

Propagation of Clerodendrum violaceum Gürke subsp. kigeziense Verdc.
Clerodendrum violaceum Gürke subsp. kigeziense Verdc. can be propagated through various methods including cuttings, division, and seedlings.
Cuttings
Cuttings are perhaps the easiest way to propagate Clerodendrum violaceum Gürke subsp. kigeziense Verdc. The process can be started by selecting healthy, young branches from the parent plant. The branches should be clean and free from diseases or pests. Once selected, the branches can be cut using a sharp pruning tool.
The cuttings should be about 6 to 8 inches long, and the bottom end should be dipped in a rooting hormone powder. The cutting should then be planted in a pot containing well-draining soil. The pot should be covered with a plastic sheet or a plastic bag to create a humid environment that will support the development of the roots.
The cutting should remain covered for 6-8 weeks, after which new growth should appear. At this point, the plastic sheet or bag can be removed, and the cutting can be transferred into a bigger container or planted outside in the garden.
Division
Another way to propagate Clerodendrum violaceum Gürke subsp. kigeziense Verdc. is through division. This method is ideal for older plants that have a lot of growth. The process entails digging up the parent plant and dividing it into smaller sections that can be replanted individually.
The divisions should have healthy roots, and each section should have a good portion of the stem and foliage. The divisions can then be replanted in pots or directly into the garden.
Seedlings
Propagation of Clerodendrum violaceum Gürke subsp. kigeziense Verdc. can also be done through seedlings. The process entails planting seeds in pots and providing the necessary care until they germinate.
The seeds should first be cleaned and soaked for a few hours to improve germination. After soaking, the seeds should be planted in small pots containing a soil mix of compost and sand. The pots should be watered and placed in a bright and warm location.
The seeds will take approximately 1 to 2 months to germinate, and the seedlings should be well taken care of by watering and fertilizing until they are strong enough to be transplanted into bigger containers or the garden.
Disease and Pest Management for Clerodendrum Violaceum Gürke subsp. Kigeziense Verdc.
Clerodendrum violaceum Gürke subsp. kigeziense Verdc., commonly known as the "Lilac clerodendrum," is an evergreen shrub native to Africa. It is a popular plant among garden enthusiasts due to its attractive features, such as its lilac-colored flowers and glossy, dark green leaves. However, like any other plant, it is susceptible to diseases and pest attacks.
Common Diseases
One of the most common diseases that affect the Lilac clerodendrum is powdery mildew. Powdery mildew is a fungal infection that forms a powdery white coating on the leaves of the plant. To manage this disease, ensure that the plant is grown in well-drained soil, and avoid excessive watering. If the plant is already infected, remove the infected leaves and dispose of them correctly. You can also apply a fungicide to prevent further damage.
Bacterial leaf spot is also a common disease that affects the Lilac clerodendrum. It is characterized by small, dark spots on the leaves that gradually enlarge, leading to browning and eventual shedding of the leaves. To manage this disease, ensure proper sanitation of the plant and its surroundings, avoiding overhead watering, and removing infected leaves and branches. You can also use copper-based fungicides to control the disease.
Common Pests
One of the most common pests that affect the Lilac clerodendrum is the spider mite. Spider mites are tiny pests that suck the sap from the plant leaves, leading to yellowing and browning of the leaves. To control spider mites, regularly spray the plant with water to wash away the pests. You can also use insecticidal soap or horticultural oil to manage spider mite infestations.
The mealybug is another pest that affects the Lilac clerodendrum. Mealybugs are soft-bodied insects that suck the sap from the plant, leading to yellowing and wilting of leaves. To manage mealybug infestations, wash the plant with a strong jet of water to remove the pests. You can also apply insecticidal soap or neem oil to control the pests.
Overall, proper cultural practices, including regular watering, feeding, and pruning, can help keep the Lilac clerodendrum healthy and less susceptible to diseases and pest attacks. Monitoring the plant regularly for any signs of disease or pests can also help in preventing severe infestations.
