Common Names
The plant is commonly known as Indian Reissantia, Asteriskanthe Reissantia, and Kagda in local dialects.
Uses
The Indian Reissantia plant is traditionally used for various medicinal purposes. The roots of the plant are used to treat fever, stomach disorders, and diarrhea. The extract from leaves is believed to reduce inflammation and heal wounds. The locals also use the plant to alleviate the symptoms of snake bites.
The bark of the plant is often used as a natural dye for fabrics. The bark's tannins produce a light brown color, which can be intensified by treatment with iron salts.
General Appearance
The Indian Reissantia plant is a perennial herb that grows to a height of about 1 meter. The stem of the plant is cylindrical, and the leaves are simple, opposite, and oval-shaped. The leaves are about 5-7 cm long and 3-4 cm wide. The flowers of the plant are small and white and are arranged in terminal cymes. The fruits of the plant are small and round, roughly 1 cm in diameter, and are light yellow when ripe.
Light Requirements
Reissantia indica var. astericantha typically grows in full sun to partial shade. It can tolerate full shade, but its growth may be stunted. In its natural habitat, the plant grows under the canopies of large trees, which provide filtered light. Indoor plants should be exposed to bright indirect light for optimal growth and development.
Temperature Requirements
Reissantia indica var. astericantha is a tropical plant and requires warm temperatures to thrive. The ideal temperature range for growth is between 20°C to 30°C. The plant can tolerate slightly cooler temperatures but may suffer from stunted growth if exposed to extreme cold. It is best to avoid exposing the plant to temperatures below 10°C.
Soil Requirements
The plant prefers well-draining soils that are rich in organic matter. Typically, the plant grows in soils that are slightly acidic, with a pH range between 5.5 and 6.5. The soil should be moist but not waterlogged, and it is important to ensure that the soil does not dry out completely between watering. A good soil mix for Reissantia indica var. astericantha is equal parts of peat moss, perlite, and vermiculite.
Cultivation Methods
Reissantia indica (Willd.) N.Hallé var. astericantha (N.Hallé) N.Hallé requires a well-drained soil mixture and plenty of sunlight to grow and thrive. It is recommended to use a peat moss-based soil mix for the plant. The ideal time to plant Reissantia indica (Willd.) N.Hallé var. astericantha (N.Hallé) N.Hallé is in early spring, as this gives the plant enough time to establish itself before the hot summer months.
Watering Needs
Reissantia indica (Willd.) N.Hallé var. astericantha (N.Hallé) N.Hallé requires regular watering, but the soil should not be kept soggy or wet. Watering once a week is usually sufficient, but this may vary depending on the climate and humidity levels. During the summer months, it is recommended to water the plant twice a week to prevent it from drying out.
Fertilization
Reissantia indica (Willd.) N.Hallé var. astericantha (N.Hallé) N.Hallé requires regular fertilization to promote healthy growth and vibrant foliage. Fertilize the plant every two weeks during the growing season, which is spring and summer. You can use a balanced fertilizer with an NPK ratio of 10-10-10 or 20-20-20. Be sure to follow the manufacturer's instructions when applying the fertilizer, as overfertilizing can damage the plant.
Pruning
Reissantia indica (Willd.) N.Hallé var. astericantha (N.Hallé) N.Hallé requires minimal pruning, but dead or damaged leaves and stems should be removed promptly to promote healthy growth. Pinching the stems can also encourage bushier growth and more compact plants. You can prune the plant in the late winter or early spring before new growth appears.
Propagation of Reissantia indica (Willd.) N.Hallé var. astericantha (N.Hallé) N.Hallé
Reissantia indica (Willd.) N.Hallé var. astericantha (N.Hallé) N.Hallé, commonly known as "Indian Fleabane," is a perennial plant that belongs to the Asteraceae family. Propagation is done through different methods:
Seeds
Propagation through seeds is the easiest and most convenient method for Reissantia indica. Collect seeds during the late summer or early fall from the mature flower heads. Dry the seeds completely before storing, making sure to keep them in a cool and dry place until ready for sowing. Sow seeds directly in well-drained soil in the spring, when the weather is warmer. Cover seeds with a thin layer of soil and keep them moist. Consider adding a layer of mulch to help retain moisture and prevent weeds from growing.
Cuttings
Propagation through cuttings can also be done, but it requires specific timing and proper conditions. Spring and summer are the best seasons for this method since the plant is actively growing. Cut 3 to 4 inches of healthy stem with at least two sets of leaves from the parent plant. Remove the lower leaves from the cutting and dip the cut end in rooting hormone. Plant the cutting in a soilless rooting medium or well-drained soil, making sure to keep it moist and under bright light. After three to four weeks, the cutting should start to grow new roots.
Division
Propagation through division is recommended for mature plants in their third or fourth year of growth. Divide the roots in the early spring by carefully digging up the plant and separating the roots with a sharp knife. Each divided section should have several healthy stems and roots attached. Plant each section in well-drained soil, keeping it moist.
Disease Management
Reissantia indica (Willd.) N.Hallé var. astericantha (N.Hallé) N.Hallé is susceptible to foliar fungal diseases such as powdery mildew, leaf spot, and rust. To manage powdery mildew, preventatively spraying the plant regularly with a solution of neem oil or sulfur can be effective. It is important to spray the plant thoroughly, covering both the upper and lower surfaces of the leaves. Leaf spot and rust can be managed by using a copper-based fungicide. Ensure that the fungicide is applied at the first sign of the disease and that it is sprayed onto both sides of the leaves as well as the stems.
Pest Management
Common pests that can affect Reissantia indica (Willd.) N.Hallé var. astericantha (N.Hallé) N.Hallé include aphids, whiteflies, spider mites, and mealybugs. To manage these pests, regularly inspect the plant for any signs of infestation. When detected, it can be helpful to use insecticidal soaps or neem oil. These natural remedies are effective at killing the pests without harming beneficial insects or the environment. Additionally, it is important to keep the plant healthy by providing adequate water, nutrients, and sunlight. A healthy plant is less likely to attract pests and diseases.
