Propagation of Leucas deflexa Hook.f. var. biglomerulata
The plant Leucas deflexa Hook.f. var. biglomerulata (Lebrun & L.Touss.) Sebald can be propagated using a few different methods. This particular variety of Leucas deflexa is a perennial herb that is native to Madagascar and is commonly known as "aomafandra" in the Malagasy language.
Seed Propagation
One method of propagating Leucas deflexa Hook.f. var. biglomerulata is through seed propagation. To do this, harvest the ripe seeds from the plant and ensure they are clean and dry. Sow these seeds into trays filled with soil and cover them lightly with soil or vermiculite. Keep the soil moist and warm, and germination should occur within 2-3 weeks. Once the seedlings have grown big enough, transplant them into individual pots or directly into the ground.
Cuttings
Another method of propagating Leucas deflexa Hook.f. var. biglomerulata is through cuttings. Take 10-15cm cuttings with a clean, sharp pair of gardening shears. Dip the cuttings into rooting hormone to enhance the chances of rooting, and plant them into a well-draining soil mix. Keep the soil damp and in a warm, sheltered spot until the cuttings have taken root. Once the cuttings have rooted, they can be transplanted into individual pots or directly into the ground.
Division
Dividing an established Leucas deflexa Hook.f. var. biglomerulata plant is another method of propagation. This can be done in the spring when new growth starts to appear. Dig up the entire plant and gently divide the plant into smaller sections, ensuring each section has a healthy root system. Replant these divisions into individual pots or directly into the ground, ensuring the soil is kept moist.
Propagation of Leucas deflexa Hook.f. var. biglomerulata can be rewarding for those interested in growing this unique and beautiful plant. Each method of propagation has its own advantages, and it is recommended to use a mix of different methods for the best results.
Disease Management
Leucas deflexa Hook.f. var. biglomerulata (Lebrun & L.Touss.) Sebald is generally a hardy plant, but it may sometimes be affected by certain diseases. Some common diseases that may affect Leucas deflexa Hook.f. var. biglomerulata include:
- Leaf spot: This is a fungal disease that causes small, circular spots on the plant's leaves. To manage this disease, it is essential to avoid overhead watering and keep the area around the plant clean. Infected leaves should be pruned and destroyed.
- Powdery mildew: This is a fungal disease that causes a white powdery substance to form on the plant's leaves. To manage this disease, it is essential to keep the plants well-spaced and to avoid overhead watering. Infected leaves should be pruned and destroyed.
- Root rot: This is a fungal disease that affects the plant's roots. To manage this disease, it is essential to avoid overwatering and to ensure adequate drainage. Infected parts of the plant should be carefully removed and destroyed.
Pest Management
Leucas deflexa Hook.f. var. biglomerulata may also be affected by certain pests. Some common pests that may affect this plant include:

- Spider mites: These are tiny mites that spin webbing on the plant's leaves. To manage this pest, it is essential to avoid dry conditions and frequent misting can be beneficial. Insecticidal soap can also be used.
- Caterpillars: These are the larval stage of certain moths and butterflies that feed on the plant's leaves. To manage this pest, it is essential to remove them manually. Bacillus thuringiensis (BT) is also an effective organic control.
Regular inspection and maintenance, including proper watering and fertilization, can help prevent diseases and pests from affecting Leucas deflexa Hook.f. var. biglomerulata. Additionally, it is essential to practice good sanitation and remove infected plant parts immediately to prevent the spread of the disease or pests to other plants.
