Origin
Drosanthemum sessile (Thunb.) Schwantes, also commonly known as the Dewflower or the Morning Sun, is a plant species originally from South Africa.
Common names
Aside from Dewflower and Morning Sun, Drosanthemum sessile also goes by other common names such as Red Iceplant, Coral Dewflower, and Rock Rose.
Uses
Drosanthemum sessile is typically cultivated as an ornamental plant, appreciated for its dainty and colorful appearance. Its bright red flowers bloom in abundance during the summer months, adding a pop of color to any garden or landscape. Additionally, it is well-suited for rock gardens and other dry, arid environments. The leaves and stems of the plant can also be used medicinally to treat various ailments such as coughs and colds, as well as for their astringent properties.
General appearance
Drosanthemum sessile is a low-growing, succulent perennial that typically reaches a height of only 4-6 inches and a width of 1-2 feet. Its leaves are small, fleshy, and cylindrical, arranged in pairs that are nearly opposite one another along the stems. These leaves grow to a length of only 0.5 to 1 cm. What makes this plant so striking, however, are the brilliant, elongated red flowers that bloom profusely throughout the summer season. These flowers can grow to be up to 3 cm in length and have a distinctive star shape.
Light Requirements
Drosanthemum sessile requires full sunlight exposure to grow properly. It can tolerate some shade, but its growth and flower production will be significantly reduced in such conditions. Therefore, it is best to grow this plant in a location where it receives at least 6 hours of direct sunlight every day.
Temperature Conditions
This plant is a warm-season succulent and thrives in warm temperatures, between 70 to 85 °F (21 to 29°C). It can tolerate temperatures as low as 50 °F (10°C), but this can negatively impact its growth and development. It is best to avoid exposing the plant to temperatures below 50 °F (10°C) for extended periods.
Soil Requirements
Drosanthemum sessile prefers well-draining, sandy soil that is slightly acidic to neutral. The soil should not retain water for extended periods, as this can cause root rot. A soil pH level of 6.0 to 7.0 is ideal for healthy growth. The addition of organic matter will also help improve the soil structure and nutrient content.
Cultivation Methods for Drosanthemum Sessile
Drosanthemum sessile, commonly known as dewflower, requires full sunlight exposure to thrive. Therefore, it is ideal to grow in rock gardens, raised beds, or containers that are strategically located where there is direct sunlight. The plant prefers well-draining soil with a pH of 6.0 to 7.5. Ensure that the soil is loose and gritty.
Watering Needs
The plant can tolerate drought but needs regular watering for optimal growth. When watering, ensure the soil is completely dry before applying water, and then the soil should be soaked until it drains through the bottom. Overwatering can lead to root rot, so ensure that the soil is allowed to dry properly between watering periods. During the winter and dormant season, the plant only needs minimal watering.
Fertilization
The plant has minimal fertilizer requirements and can survive even without fertilization. However, if you want to provide extra nutrients, use a balanced, slow-release fertilizer at the beginning of the growing season. Over-fertilizing can lead to poor growth and stunted plant development.
Pruning Drosanthemum Sessile
Drosanthemum sessile requires minimal pruning, but deadheading the faded flowers can help encourage new growth. Pruning can be done at any time during the growing season, but it is recommended to prune at the end of flowering. This encourages the plant to develop new growth that will promote flowering in the next growing season. Cut back any dead or damaged stems, or prune to shape the plant.
Propagation of Drosanthemum Sessile
Drosanthemum sessile (Thunb.) Schwantes, commonly known as the dewflower or mid-day flower, is a succulent plant popularly cultivated for its bright and colorful flowers. The plant can be propagated through various methods, including:
Seeds
Propagation of Drosanthemum sessile from seeds is a viable option. The seeds should be sown in well-drained soil, preferably sandy or gravelly soil. The soil should be moist but not wet, and the seeds should be covered with a thin layer of soil. It is recommended to plant the seeds in early spring or late fall, and the plants tend to flower after around two years of growth.
Cuttings
Propagation of Drosanthemum sessile from cuttings is another option. The cuttings should be taken from healthy plants in the spring or summer, preferably from the tips of the stems. After taking the cuttings, they should be left to callus for a few days before planting. The cuttings should be planted deep enough in the well-drained soil and should be watered sparingly until they develop roots.
Division
Propagation of Drosanthemum sessile through division involves separating the plant into multiple parts to create new plants. This method is ideal for mature plants and is typically done during the spring or summer when the plant is actively growing. The plant is carefully dug up, and the roots are separated into multiple parts. Each section should have sufficient roots, and plant them in individual pots filled with well-draining soil.
Disease and Pest Management for Drosanthemum sessile (Thunb.) Schwantes plant
Drosanthemum sessile (Thunb.) Schwantes, commonly known as dewflower, is a succulent that is native to South Africa. While it is relatively easy to care for, this plant is still susceptible to a number of diseases and pests. Here are some common issues that can affect your Drosanthemum sessile and how to manage them:
Diseases
Fungal Leaf Spot: This disease is characterized by brown spots on the leaves. It is caused by fungal spores that thrive in warm, moist conditions. To manage fungal leaf spot, remove the affected leaves and dispose of them. Reduce the humidity around the plant and avoid getting water on the leaves. You may also use a fungicide to treat the plant.
Rust: Rust is caused by fungus and is often seen in the form of small reddish or yellowish-brown spots on the leaves. As the disease progresses, these spots can turn into large, raised pustules that can burst open, releasing more spores. To manage rust, remove the affected leaves and dispose of them. Avoid overhead watering and increase the amount of light the plant receives.
Pests
Spider Mites: These tiny pests are not visible to the naked eye, but their presence can be seen through yellowing, speckled foliage. Infestations are often caused by dry conditions, so increasing the humidity levels around the plants and misting them frequently can be helpful. You can also treat spider mites with insecticidal soap.
Mealybugs: These small, white insects often conceal themselves in the crevices or leaf axils of the plant. You can spot their infestation by seeing cotton-like patches on the plant. They suck the sap from the plant and can cause the leaves to become yellow. Remove them manually with the help of alcohol. If the infestation is severe, use an insecticide.
By being vigilant and proactive, you can help keep your Drosanthemum sessile healthy and free of pests and diseases. With proper management, this plant can thrive for many years.
