Common Names:
The plant is commonly known as Graham's bundleflower, Graham's sensitive-plant, or Graham's prickleleaf.
Uses:
Meibomia grahamii has several uses in traditional medicine. The plant contains compounds that possess anti-inflammatory and antioxidant properties, and have been used to treat several illnesses including fever, cough, and skin diseases. Additionally, the plant is a great source of food for livestock as they graze on it.
General Appearance:
Meibomia grahamii is a perennial plant that grows up to 1m tall. It has a branching stem with prickly compound leaves that resemble a bundle of twigs. The flowers are small and white or pink and bloom in clusters in the spring and summer months. The fruits produced by the plant are flattened, brown legumes that contain black seeds.
Growth Conditions for Meibomia grahamii (Gray) Kuntze
Meibomia grahamii (Gray) Kuntze, commonly known as Graham's bundleflower, is a perennial herb that belongs to the legume family. It is native to North America and grows in prairies, meadows, and other open habitats.
Light Requirements
Graham's bundleflower is a plant that requires full sun exposure to grow properly. It tolerates some shading, but growth is significantly reduced in the absence of sunlight. Therefore, it is essential to plant these in areas that receive ample sunlight.
Temperature Requirements
Graham's bundleflower is a plant that is native to North America and is well adapted to various climatic conditions. However, it grows best in warm climates that experience hot summers and mild winters. The plant can tolerate temperatures as low as -15°C and as high as 40°C.
Soil Requirements
Graham's bundleflower is a plant that grows well in a wide range of soil types, including loamy, sandy, and clay soils. It prefers moist, well-drained soils, but can also grow in drier soils. The plant is tolerant of alkaline soils with a pH of up to 7.5.
Cultivation Methods:
Meibomia grahamii thrives in well-drained, fertile soil. The plant requires full sun to partial shade for optimal growth. The ideal temperature range for this plant is between 20 to 35 degree Celsius. With proper care, this plant can grow up to 30 inches tall and spread 24 inches wide.
Watering Needs:
Meibomia grahamii requires regular watering during the growing season. The soil must be kept consistently moist, but not waterlogged, to ensure healthy plant growth. However, the plant is tolerant of short drought periods and can recover quickly with proper watering. Watering should be decreased during the dormant season to prevent root rot.
Fertilization:
Meibomia grahamii requires a balanced and slow-release fertilizer application during the growing season. The fertilizer should be applied once a month or as directed by the manufacturer's instructions. Over-fertilization can cause leggy growth and may reduce flowering. It is recommended to stop fertilizer application during the dormant season.
Pruning:
Meibomia grahamii requires pruning to maintain its shape and promote healthy growth. Pruning should be done during the dormant season or after flowering to prevent reduce floral display. The plant should be pruned to maintain a rounded shape, remove dead or diseased wood and to promote air circulation. Avoid over-pruning to prevent damage to the plant's growth.
Propagating Meibomia Grahamii (Gray) Kuntze Plants
The Meibomia grahamii plant can be propagated through both sexual and asexual means. The following propagation methods can be employed:
Seeds
Propagation through seeds is a common method, although it can be time-consuming. Seeds should be obtained from a reliable source to ensure they are of good quality. Freshly harvested seeds should be sown immediately while old seed should be stored in a cool, dry place. The seed should be sown on a well-prepared seedbed, preferably using fine soil. Once the seedlings emerge, they should be carefully thinned to avoid overcrowding.
Cuttings
Propagation through cuttings is an asexual method, and it provides faster results compared to seed propagation. Both hard and softwood cuttings can be used to propagate Meibomia grahamii. Hardwood cuttings should be taken during the dormant season, while softwood cuttings should be taken during the growing period. After taking the cuttings, they should be treated with rooting hormone and placed in soil that is well-drained. The soil should be watered frequently to keep it moist.
Division
Another asexual method for propagating Meibomia grahamii is division. The plant should be lifted from the ground, and its root system should be carefully separated into sections. Each section should have a few leafy shoots and a well-developed root system. The divided plants should be planted in well-prepared soil and watered adequately to accelerate growth.
Disease Management
Meibomia grahamii is a relatively disease-resistant plant, but it can still fall prey to some diseases. Some common diseases that might affect the plant include:
- Anthracnose: This disease is caused by a fungus and results in brown spots on leaves and stems. Infected areas eventually turn black and may fall off. To manage anthracnose, prune infected areas and properly sanitize pruning tools. Fungicide applications may also be necessary.
- Leaf spot: Leaf spots are caused by various fungal or bacterial pathogens and result in small to large circular spots on the leaves. The spots may be brown, black, or purple. To manage leaf spot, remove infected leaves and apply fungicide as needed.
- Powdery mildew: This disease appears as a white powdery coating on the plant's foliage. It is caused by a fungal infection and often affects plants grown in humid conditions. To manage powdery mildew, use cultural practices such as proper spacing and ventilation to minimize humidity. Fungicide applications may also be necessary.
Pest Management
Meibomia grahamii is generally not a target for pests, but some insects can cause problems. Some common pests that might affect the plant include:
- Spider mites: Spider mites are tiny, sap-sucking insects that can cause leaf yellowing and loss. To manage spider mites, increase humidity around the plant with a humidifier or by misting the leaves. Insecticidal soap or neem oil can also be used.
- Aphids: Aphids are small, pear-shaped insects that feed on plant sap and excrete a sticky substance called honeydew. They can cause leaf curling and yellowing. To manage aphids, prune off infected parts and use insecticidal soap or neem oil.
- Caterpillars: Caterpillars are the larval stage of moths or butterflies and can cause leaf damage by feeding on them. To manage caterpillars, handpick them off the plant and use Bacillus thuringiensis (BT) or other insecticides.
