The leaves are used to alleviate skin irritations and to treat wounds. The plant is also used in African traditional medicine to treat dysentery.
Additionally, Boehm's dayflower is sometimes grown as an ornamental plant. Its small, blue flowers add a splash of color to gardens and it is often used as a groundcover. It can also be grown in containers or hanging baskets.
Light Conditions
Commelina africana L. var. boehmiana is known to grow well in conditions of partial to full sunlight. However, it is important to note that it may not tolerate extremely intense sunlight and may require some shade during the hottest parts of the day.
Temperature Conditions
This plant typically grows well in warm to hot temperature conditions. The ideal temperature range for Commelina africana L. var. boehmiana growth is between 20°C and 30°C. It is important to note that this plant may not tolerate frost and is typically grown in regions with mild winters.
Soil Requirements
This plant prefers well-draining soils that are rich in organic matter. Commelina africana L. var. boehmiana tends to grow best in soils with a pH range of 5.5 to 7.5. Additionally, this plant may prefer slightly sandy soils that provide good drainage and aeration. Adequate soil moisture is also important for the growth of this plant, and as such, it is typically grown in areas with consistent rainfall or where irrigation systems are available.
Cultivation Methods
Commelina africana L. var. boehmiana (K.Schum.) Brenan, commonly known as African Dayflower, is a perennial herb that can be grown in various soil types. It prefers well-draining soil rich in organic matter and can be grown in full sun or partial shade. In areas with high temperatures, it grows best in shade to avoid scorching. It can be propagated from seeds or by dividing mature plants and replanting in a new location.
Watering Needs
African Dayflower requires moderate watering and prefers to be kept moist but not soaked. During the summer months, it should be watered more frequently to compensate for any moisture loss due to high temperatures. Avoid overhead watering as the leaves of this plant are susceptible to fungal diseases.
Fertilization
This plant does not require regular fertilization, but it can benefit from the application of a balanced fertilizer once a year. It is recommended to fertilize in early spring when the plant begins to actively grow. Avoid over-fertilizing as it can lead to excessive foliage growth with fewer flowers.
Pruning
Pruning African Dayflower is not necessary, but occasional deadheading can promote more blooms. Cut back the spent flowers to just above a leaf node to encourage the plant to produce more flowers. It is also recommended to cut back any damaged or dead foliage to keep the plant healthy and looking its best.
Propagation of Commelina africana L. var. boehmiana (K.Schum.) Brenan
Commelina africana L. var. boehmiana (K.Schum.) Brenan, commonly known as African dayflower, is a beautiful plant that can be propagated through different methods. Here are some of the propagation methods:
Division
Division is the easiest and most common method of propagating Commelina africana. It involves dividing the plant into several smaller sections, each with its own roots. To do this, carefully dig up the plant and separate the roots with a sharp knife or garden shears. Make sure each section has at least one healthy shoot and a good root system.
Stem Cuttings
Propagating Commelina africana through stem cuttings is also possible. To do this, take a stem cutting from a healthy plant, making sure it's at least 4-6 inches long. Remove the leaves from the bottom half of the stem and dip the cut side into rooting hormone. Place the stem into a well-draining potting mixture and water it lightly. Cover the plant with a plastic bag or clear plastic wrap to help keep moisture in. After a few weeks, the plant should start growing roots, and you can remove the plastic covering.
Seeds
Commelina africana can also be propagated through seeds. Collect the seeds from a healthy plant and sow them in a well-draining potting mix. Keep the soil moist, and place the pot in a warm, preferably sunny area. The seeds should germinate within a few weeks. Once the seeds have germinated, you can transplant the seedlings into individual pots or directly into the ground.
Disease Management
Commelina africana L. var. boehmiana (K.Schum.) Brenan is prone to various diseases, including:
- Leaf Spot: exhibits as spots on the leaves, which may be circular, angular or irregular. They may be grey, brown, or white with dark borders. To manage this disease, the affected leaves should be removed and destroyed, and the plant should be sprayed with fungicide.
- Rust: causes rust-colored pustules to form on the leaves. The leaves may then turn yellow and eventually fall off. To manage this disease, the affected plant should be sprayed with fungicide, and the infected leaves should be removed and destroyed.
- Root Rot: is caused by fungi that attack the roots of the plant, resulting in stunted growth and death. To manage this disease, proper soil drainage and watering practices should be maintained, and the affected areas should be treated with a fungicide.
Pest Management
Commelina africana L. var. boehmiana (K.Schum.) Brenan is also susceptible to pest infestations, including:
- Spider Mites: cause small yellow or white spots on the leaves, leading to the leaves turning brown and brittle. To manage this pest, the plant should be sprayed with insecticidal soap or an organic pesticide.
- Whiteflies: are tiny white insects that suck sap from the plant. This results in the leaves turning yellow and the plant becoming stunted. To manage this pest, the plant should be sprayed with neem oil or insecticidal soap.
- Caterpillars: are the larvae of moths and butterflies that eat the leaves of the plant. To manage this pest, the caterpillars should be removed by hand, and the plant should be sprayed with an organic pesticide.
