Origin
Cyanthillium stelluliferum, also known as the starbur or lesser starwort, is a plant species native to tropical and subtropical Asia. It is commonly found in countries such as India, Sri Lanka, Thailand, and Vietnam, among others.
Common Names
Aside from starbur and lesser starwort, Cyanthillium stelluliferum has other common names in different parts of the world. In India, it is known as khokali, while in Sri Lanka, it is called murikankattai. In Thailand, it is referred to as yaa bai thong, and in Vietnam, it is known as c?t l?n ho?c c? ratalia.
Uses
Cyanthillium stelluliferum is widely used in traditional medicine to treat various ailments such as asthma, bronchitis, and diabetes. Its leaves and stems contain flavonoids, alkaloids, and other active compounds that exhibit anti-inflammatory, analgesic, and anti-diabetic activities. In some countries, the plant is also used as a natural insecticide and as an ornamental plant.
General Appearance
Cyanthillium stelluliferum is an annual herb that grows up to 60 cm tall. Its stems are erect, branchy, and covered with fine white hair. The leaves are simple, alternate, and serrated, measuring 2-5 cm long and 1-3 cm wide. The inflorescence is composed of numerous small, white, star-shaped flowers that are densely packed together, forming a rounded head. The fruit is an achene, measuring around 1.5 mm long and 0.5 mm wide, with a tuft of silky white hair at the top.
Light Requirements
Cyanthillium stelluliferum thrives in areas with full sunlight exposure. It requires at least 6 hours of direct sunlight per day to grow and develop properly. Exposure to sunlight aids in its photosynthetic activities, which is important for its growth and survival.
Temperature Requirements
This plant species requires warm temperatures to grow. The optimal temperature for its growth is between 20°C to 30°C. However, it is still capable of tolerating high temperatures of up to 40°C.
Soil Requirements
Cyanthillium stelluliferum has the ability to grow in a variety of soil types. However, it prefers well-drained soils that are rich in organic matter. The soil should have a pH between 6 to 7.5. It can also tolerate slightly acidic to slightly alkaline soil conditions.
Cultivation
Cyanthillium stelluliferum (Benth.) H.Rob., commonly known as the starved daisy, is a hardy perennial plant that thrives in tropical and subtropical climates. It can be easily propagated from seed, which should be planted during the rainy season either directly into the ground or in seedling trays. The seedlings should be transplanted to their permanent location as soon as they acquire four to six leaves.
Watering Needs
Cyanthillium stelluliferum requires frequent watering, especially during dry spells. However, overwatering can lead to root rot, so it is essential to strike a balance. Water the plant every two to three days, keeping an eye on the soil moisture level. The soil should be kept moist but not soggy.
Fertilization
The starved daisy is not a heavy feeder and does not require regular fertilization. However, a boost of nutrients during the flowering season can help promote healthy growth and abundant blooms. Use a balanced fertilizer with equal parts of nitrogen, phosphorus, and potassium once a month during the growing season.
Pruning
Cyanthillium stelluliferum does not require regular pruning, but it can be beneficial to remove dead or damaged foliage to encourage new growth. Pinching back the tips of the plant during the growing season can help promote bushier growth and more blooms. However, pruning should not be done excessively as it can lead to stunted growth and fewer flowers.
Propagation of Cyanthillium stelluliferum (Benth.) H.Rob.
Cyanthillium stelluliferum (Benth.) H.Rob., also known as the Starbur plant or Bintangor, is a fast-growing ornamental plant that can be propagated by several methods:
Propagation by Seed
One of the easiest and most common methods of propagating Cyanthillium stelluliferum is by seed. The seeds can be sown directly in the ground or in pots filled with well-draining soil. It is best to plant the seeds during the rainy season, as the plant prefers moist conditions to grow.
Propagation by Stem Cuttings
Cyanthillium stelluliferum can also be propagated by stem cuttings. To do this, simply cut a 4-6 inch section of stem from a healthy plant and remove the leaves from the lower half of the cutting. Dip the cut end of the stem into rooting hormone powder and plant it in a pot filled with well-draining soil. Keep the soil moist and in a few weeks, new roots should begin to take hold.
Propagation by Division
Another way to propagate Cyanthillium stelluliferum is by division. This method is best used on mature plants that are at least 2-3 years old. Dig up the plant and divide the root ball into sections, making sure each section has several stems and an adequate root system. Replant the sections in well-draining soil and keep the soil moist until new growth appears.
Regardless of the propagation method used, it is important to keep the newly propagated plants in a warm and shaded area until they become established. Cyanthillium stelluliferum is a relatively low-maintenance plant that can flourish in a variety of environments, making it a great addition to any garden or landscape.
Disease Management for Cyanthillium stelluliferum
Cyanthillium stelluliferum is relatively resistant to diseases, but it may still fall victim to some common diseases.
Leaf Spot: Leaf spot is a common disease that affects many plants, including Cyanthillium stelluliferum. The disease is caused by fungi, and it can result in the appearance of yellow, brown, or black spots on the leaves of the plant. To manage leaf spot disease, remove the affected leaves and dispose of them. Avoid watering the plant from above, as this can help spread the disease. Fungicides can also be used to manage the disease.
Root Rot: Root rot is a soil-borne disease that affects the roots of the plant. The disease is caused by fungi, and it can cause the plant to wilt and die. To manage root rot disease, avoid overwatering the plant and make sure it is planted in well-draining soil. Fungicides can also be used to manage the disease.
Pest Management for Cyanthillium stelluliferum
Some pests that can potentially affect Cyanthillium stelluliferum include:
Aphids: Aphids are small, sap-sucking insects that can feed on the leaves of the plant. To manage aphids, introduce natural predators like ladybugs or lacewings, or use insecticidal soap or neem oil.
Spider mites: Spider mites are tiny pests that can suck the sap from the leaves of the plant. They are difficult to see with the naked eye, but if the leaves of the plant are turning yellow or appear stippled, it may be a sign of a spider mite infestation. To manage spider mites, spray the plant with a strong jet of water to knock them off, or use insecticidal soap or neem oil.
Caterpillars: Caterpillars can feed on the leaves of the plant and cause significant damage. To manage caterpillars, remove them by hand if possible or use Bacillus thuringiensis (BT), a natural insecticide that only affects caterpillars.
Snails and slugs: Snails and slugs can feed on the leaves of the plant and cause significant damage. To manage them, handpick them off the plant or use a slug bait.
