Drosanthemum subcompressum (Haw.) Schwantes is a flowering succulent that belongs to the Aizoaceae family. It is commonly known as "revolver," "basil plant," or "vygie" and is native to South Africa.
Appearance of Drosanthemum subcompressum
Drosanthemum subcompressum is a low-growing, spreading plant that typically reaches a height of 6 to 8 inches and a width of up to 2 feet. It has small, fleshy, cylindrical leaves that are green or bluish-green in color and arranged in clusters along the stems. The leaves are covered in tiny hairs known as trichomes, which give them a velvety texture.
During the summer months, the plant produces small, showy, daisy-like flowers that range in color from white, pink, orange, yellow, to red. The flowers usually open in the afternoon and close in the evening, hence the common name "revolver."
Uses of Drosanthemum subcompressum
Drosanthemum subcompressum is commonly grown as an ornamental plant in rock gardens, containers, and hanging baskets. It is drought-tolerant and prefers full sun or partial shade, making it an ideal plant for hot, dry climates.
The leaves and flowers of the plant are edible and have been used in traditional South African cuisine. The leaves have a slightly sour taste, and the flowers add color and flavor to salads and stews.
Additionally, the plant has medicinal uses and has been used to treat various ailments such as diarrhea, fever, and stomach problems.
Light Requirements
The Drosanthemum subcompressum plant requires full sun to partial shade, and it should be grown in an area where it can receive at least 6 hours of direct sunlight each day. If it is grown in too much shade, it may become leggy and have a weaker stem.
Temperature Requirements
Drosanthemum subcompressum is a plant that comes from South Africa and prefers warm to hot temperatures. It thrives in USDA hardiness zones 9 to 11. Its growth is optimal when the temperature is between 60-80°F (15-27°C). Temperatures below 50°F (10°C) should be avoided as it may harm the plant.
Soil Requirements
Drosanthemum subcompressum prefers well-drained soil and sand or loam-heavy soil. The soil should have a pH of 5.5 to 7.5. It should be kept moist but not waterlogged to prevent root rot. A mix of cactus soil and a good-quality potting mix can be suitable for this plant. Adding pebbles or small rocks at the bottom of the pot can improve drainage.
Cultivation Method
Drosanthemum subcompressum is a hardy succulent and is easy to cultivate. It prefers a sunny location that is sheltered from the wind. The plant needs well-drained soil that is rich in organic matter. The soil should be slightly acidic with a pH range of 5.0 to 6.5. It is recommended to grow the plant in a well-draining potting mix that is specially made for succulents.
Watering Needs
The watering needs of Drosanthemum subcompressum are minimal. The plant requires moderate watering during the growing season, but it can tolerate drought conditions. It is essential to water the plant only when the topsoil is dry. Overwatering can lead to root rot and cause irreversible damage to the plant. It is advisable to avoid water logging the soil.
Fertilization
Drosanthemum subcompressum does not require frequent fertilization. It is sufficient to fertilize the plant once a month during the growing season with a balanced fertilizer. It is advisable to dilute the fertilizer solution to half strength before application. Overfertilization can lead to excessive vegetative growth, which can weaken the plant and make it more susceptible to diseases.
Pruning
Drosanthemum subcompressum does not require frequent pruning. The plant has a natural growth habit and usually maintains its shape. However, it is advisable to remove any dead, damaged, or diseased parts of the plant. It can be done by cutting the affected parts with a sharp, sterile pair of scissors. Pruning should be done during the growing season to avoid stressing the plant.
Propagation methods for Drosanthemum subcompressum
Drosanthemum subcompressum, commonly known as the 'Dewdrop', is a beautiful succulent with fleshy green leaves and bright yellow flowers. It is easy to propagate and can be propagated using different methods such as:
Seed propagation
Propagation of Drosanthemum subcompressum through seeds is relatively easy. Harvest the seeds from the mature plant and plant them in well-draining soil in a small container. Cover the container with a clear plastic sheet, and place it in a warm, bright area. Water the container lightly when the soil feels dry, but avoid overwatering. Germination will usually occur within 2 to 4 weeks, after which you can remove the plastic cover and move the container to a sunny area.
Leaf and stem cutting propagation
Drosanthemum subcompressum can also be propagated through leaf and stem cuttings. Cut a healthy leaf or stem from the plant, and leave it to dry in a shaded area for a few days. Once the cuttings have dried out, plant them in coarse, sandy soil and water them sparingly. It is essential to avoid overwatering as this can cause the cutting to rot. Place the container in a sunny location and wait for new growth to appear.
Division propagation
Drosanthemum subcompressum can be divided to propagate it. Gently remove the plant from the soil and look for any visible offsets. Carefully separate the offsets from the parent plant, and plant them in their separate containers with well-draining soil. Keep them in a bright, warm location, watering sparingly until they establish roots and new growth begins to appear.
With these easy and reliable propagation methods, you can propagate Drosanthemum subcompressum with ease and increase your succulent collection.
Disease Management for Drosanthemum subcompressum
Drosanthemum subcompressum is susceptible to various diseases, including:
- Fungal leaf spot: This is identified by the presence of small, black or brown spots on the leaves. To manage this disease, affected leaves should be removed and destroyed immediately. Fungicides can also be used to control the disease.
- Root rot: This disease can cause wilting and yellowing of the plant's leaves, as well as stunted growth. Proper drainage and avoiding overwatering can prevent root rot from occurring. Infected plants should be removed to avoid the spread of the disease.
- Powdery mildew: This is a fungal disease that appears as a white, powdery substance on the leaves. To manage powdery mildew, affected plants should be isolated, and fungicides can be used to control the disease.
Pest Management for Drosanthemum subcompressum
Drosanthemum subcompressum is also vulnerable to pest infestation, including:
- Aphids: These are small insects that suck sap from the plant's leaves. The presence of sticky residue on the leaves is a sign of aphid infestation. To manage this pest, insecticidal soap can be used, or natural predators such as ladybugs can be introduced.
- Spider mites: These pests cause yellowing and stippling of the leaves. They can be eliminated with the use of miticides or by spraying the plant with water to dislodge them.
- Mealybugs: These are small, white, cotton-like insects that feed on the sap of the plant. The use of insecticidal soap, natural predators, or manually removing them can help manage mealybug infestations.
