In traditional medicine, the plant has been used to treat coughs, colds, and stomach ailments. The leaves and flowers of the plant are crushed and mixed with water or other liquids to form a decoction, which is ingested orally.
General Appearance
The Madagascar Daisy is a small, bushy shrub that grows to a height of about 60 centimetres. It has slender, green stems with small, oval-shaped leaves that are arranged in an alternate pattern. The plant produces bright yellow flowers that measure about 3 centimetres in diameter and have a distinctive central disc of dark-coloured florets. The plants are relatively easy to grow, and they prefer moist, well-drained soil and partial sun exposure.
Light Requirements
Agathisanthemum bojeri Klotzsch var. glabriflorum Bremek. prefers full sunlight exposure for optimal growth and requires at least six hours of direct sunlight exposure per day. Without adequate sunlight, the plant may not produce flowers or may develop weak stems and leaves. Therefore, it is best to place the plant in a south-facing direction where it can receive maximum sunlight.
Temperature Requirements
The plant prefers warm temperatures ranging from 65°F to 80°F (18°C to 27°C) and cannot tolerate frost or extreme heat. The ideal temperature range for the plant is between 70°F and 75°F (21°C to 23°C). It is best to keep the plant away from drafty windows or doors as cold temperatures and harsh winds can damage its foliage and overall growth.
Soil Requirements
Agathisanthemum bojeri Klotzsch var. glabriflorum Bremek. requires well-draining soil to prevent waterlogging. The ideal soil pH range is between 6.0 and 7.5, with a mix of organic matter for optimal growth. It is necessary to avoid using heavy clay soils and instead opt for loamy soils enriched with compost and other organic matter. A well-draining potting mix with peat moss, perlite, and vermiculite in equal parts is also suitable for the plant.
Cultivation Methods
Agathisanthemum bojeri Klotzsch var. glabriflorum Bremek. is a fairly easy plant to cultivate. It does best in well-draining soil and full sun to partial shade. The plant also likes warm and humid conditions and requires a temperature between 18 to 26 degrees Celsius. This plant can also be propagated by cuttings or seeds.
Watering Needs
It is important to keep the soil of Agathisanthemum bojeri Klotzsch var. glabriflorum Bremek. consistently moist but not waterlogged. Allow the top of the soil to dry out slightly between waterings. Overwatering can lead to root rot, so it is important not to let the plant sit in standing water.
Fertilization
Agathisanthemum bojeri Klotzsch var. glabriflorum Bremek. is not a heavy feeder but will benefit from occasional fertilization. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Feed the plant once a month during the growing season and stop feeding during the winter months.
Pruning
Agathisanthemum bojeri Klotzsch var. glabriflorum Bremek. can be pruned to keep its shape and to encourage bushier growth. Prune the plant in late winter or early spring before it enters its growing season. Remove any dead or damaged growth and cut back any stems that are too long or leggy. Avoid excessive pruning, as this can reduce the number of flowers the plant produces.
Propagation of Agathisanthemum bojeri Klotzsch var. glabriflorum Bremek.
Agathisanthemum bojeri Klotzsch var. glabriflorum Bremek. can be propagated by various methods.
Seed propagation
The easiest and most common method of propagating Agathisanthemum bojeri Klotzsch var. glabriflorum Bremek. is by seeds. The seeds can be collected from mature fruit pods. The collected seeds should be cleaned and dried, and then stored in a cool, dry place until they are ready to be sown.
To sow the seeds, prepare a well-draining soil mix with sand and vermiculite. Sow the seeds on the surface of the soil mix and cover lightly with the same mix. Keep the soil moist but not wet, and place the container in a warm, bright area. Germination should occur within two to three weeks.
Cuttings propagation
Agathisanthemum bojeri Klotzsch var. glabriflorum Bremek. can also be propagated by stem cuttings. Cuttings should be taken from strong, healthy plants in the spring or summer. The stem cuttings should be between 4-6 inches in length and should be taken from the tip of the stem.
Dip the cut end of the stem cutting into rooting hormone and plant the cutting in a well-draining soil mix. Place the container in a warm, bright area but out of direct sunlight. Keep the soil moist but not overly wet. In about four to six weeks, the cutting should have roots and be ready to transplant into its permanent location.
Division propagation
Agathisanthemum bojeri Klotzsch var. glabriflorum Bremek. can also be propagated by dividing the roots of an established plant. This method should be done in the spring or fall when the plant is not in bloom.
To divide the plant, dig up the entire root ball and gently pull apart the roots into smaller sections. Each section should have a minimum of three stems and a healthy root system. Plant each section in a well-draining soil mix and water until the plant is established.
Propagation of Agathisanthemum bojeri Klotzsch var. glabriflorum Bremek. can be easily done by following the above-mentioned methods. It is important to keep the soil moist and provide bright light but avoid direct sunlight.

Agathisanthemum bojeri Klotzsch var. glabriflorum Bremek. is a plant that is prone to several diseases and pests. Proper disease and pest management strategies are necessary to maintain the health and vigor of this plant.
Common Diseases
Fungal leaf spot: Fungal leaf spot is a common disease that affects Agathisanthemum bojeri Klotzsch var. glabriflorum Bremek. The symptoms include small brown spots on the leaves that can spread and cause the leaves to yellow and fall off. To manage this disease, remove the infected leaves and ensure the plant is well-ventilated.
Crown and root rot: Crown and root rot is a fungal disease that affects the roots of Agathisanthemum bojeri Klotzsch var. glabriflorum Bremek. It causes the roots to turn brown and mushy, and the plants may wilt or die. To manage this disease, avoid overwatering and ensure proper drainage. If the plant is already infected, remove it and its surrounding soil to prevent the disease from spreading.
Common Pests
Aphids: Aphids are small sucking insects that can affect all parts of the plant. They cause the leaves to curl and may stunt the growth of the plant. To manage aphids, use insecticidal soap or neem oil. Alternatively, blast them off the plant with a strong stream of water.
Spider mites: Spider mites are tiny insects that thrive in hot and dry conditions. They cause the leaves to turn yellow and may cause webbing on the plant. To manage spider mites, ensure the plant is well-hydrated and mist the leaves to increase humidity. Alternatively, use insecticidal soap or neem oil to control the infestation.
Implementing these disease and pest management strategies for Agathisanthemum bojeri Klotzsch var. glabriflorum Bremek. can help maintain the health and appearance of the plant, ensuring it grows to its full potential.
