Introduction

Thlaspi africanum Burm.f., commonly known as African pennywort, is a medicinal plant species that belongs to the Brassicaceae family. This plant is native to Ethiopia, Eritrea, and Somalia in Africa and can also be found in some other parts of the world, including South America and Asia.

General Appearance

The African pennywort is a small annual or biennial herb that usually grows up to 60 cm in height. Its stem is erect and branched, with rough and hairy leaves measuring between 3 and 5 cm long. The leaves are somewhat lobed and have jagged margins, and their color can range from light green to yellowish-green. The flowers are small, white or pink, and have four petals. The seeds are tiny, round, and dark-brown in color.

Common names

Aside from its scientific name, the African pennywort is also known by several other common names, including: - Abyssinian cress - Ethiopian cress - Ethiopian pennywort - Ethiopian watercress - Netch azmud

Uses

The African pennywort has been used extensively in traditional medicine for centuries to treat a variety of ailments, including: - Wounds and burns - Skin conditions, such as eczema and psoriasis - Respiratory infections and disorders, such as coughs, asthma, and pulmonary tuberculosis - Digestive problems, such as indigestion, nausea, and stomach ulcers - Urinary tract infections and kidney problems Today, the plant is still used for its medicinal properties, and its extracts are used in the pharmaceutical and cosmetic industries. The African pennywort is also used as a culinary herb and in traditional dishes in Ethiopia and Eritrea.

Light Requirements

Thlaspi africanum Burm.f. is a plant that requires full sun to grow properly. This plant needs an ample amount of sunlight to carry out photosynthesis, which is essential for its growth. When there is insufficient light, the plant will have stunted growth and elongated stems, causing it to become lanky and weak. Therefore, it is best to place Thlaspi africanum Burm.f. in an area where it can receive enough sunlight.

Temperature Requirements

Thlaspi africanum Burm.f. thrives in a temperature range of 16°C to 24°C. At a temperature below 10°C, the plant will become dormant, and growth will slow down. If exposed to temperatures above 24°C, Thlaspi africanum Burm.f. will be stressed, and it will not grow properly. Therefore, it's essential to provide a moderate temperature range for the plant to maintain steady growth.

Soil Requirements

Thlaspi africanum Burm.f. prefers a well-draining soil with a pH level of 6.5 to 7.5. The soil should also be rich in organic matter and nutrients such as nitrogen, phosphorus, and potassium. The plant cannot sustain its growth in compacted soil, as it restricts root growth and prevents them from absorbing the necessary nutrients. Therefore, the soil should be loose so that the roots can spread out and absorb nutrients easily. In summary, Thlaspi africanum Burm.f. needs a fertile, well-drained soil with a pH level between 6.5 to 7.5 to thrive.

Cultivation Methods

Thlaspi africanum Burm.f. is an annual herb that is easy to grow and manage. The plant grows best in well-drained soils with rich organic matter. It is recommended to plant the seeds in the late winter or early spring after the last frost. The seeds can be directly sown into the soil, and a thin layer of soil should be sprinkled on top. The plant prefers full sun but can tolerate light shade.

Watering Needs

The plant requires moderate watering. The soil should be slightly moist but not waterlogged. Overwatering can lead to root rot and other diseases. It is recommended to water the plant once a week, or more frequently if the soil is dry. The best time to water the plant is early in the morning or late in the evening when the sun is not too hot.

Fertilization

The plant requires regular fertilization to enhance growth and encourage blooming. It is recommended to use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. The fertilizer should be applied every two weeks, or as directed on the package instructions. Organic fertilizers like compost and well-rotted manure can be used, especially in the early stages of growth.

Pruning

Thlaspi africanum Burm.f. does not require any special pruning. However, to encourage bushier growth and more prolific blooming, it is recommended to pinch the tips of the plant when it reaches about six inches in height. This will encourage branching and more flower production. Deadheading, or removing spent flowers, will also promote more blooming and keep the plant looking neat and tidy.

Propagation of Thlaspi africanum Burm.f.

Thlaspi africanum Burm.f., also known as African penny cress, is a hardy plant that grows well in temperate climates. Propagation of this plant can be done using seeds or stem cuttings.

Propagation through Seeds

The easiest method to propagate Thlaspi africanum Burm.f. is through seeds. The seeds can be collected from mature plants during fall or winter and stored until the beginning of spring. Before sowing, the seeds should be soaked overnight in water to hasten the germination process. The seeds should then be sown in well-draining soil mixed with organic matter and kept moist but not waterlogged. Germination usually takes two to four weeks and the seedlings can be transplanted once they have developed a few true leaves.

Propagation through Stem Cuttings

Propagation through stem cuttings is another method used to propagate Thlaspi africanum Burm.f. This method involves collecting healthy stem cuttings during the plant's growing season. The stem cuttings should be around 4-6 inches in length, with at least two nodes. The bottom leaves on the stem should be removed and the cuttings should be dipped in rooting hormone before being placed in well-draining soil. The soil should be kept moist and the cuttings should be covered with a plastic bag or placed in a greenhouse until roots have developed. Once the new plants have developed good root systems, they can be transplanted to individual pots and kept in a shaded area for a week or two before moving to their final location.

Disease Management

Thlaspi africanum Burm.f. is generally a healthy plant and is not commonly affected by diseases. However, some diseases that may affect this plant include:

• Downy Mildew - This is a fungal disease that causes white patches on the undersides of leaves and a grayish mold on the upper surface. To manage downy mildew, it is important to remove and destroy infected plant parts and to improve air circulation around the plant. Avoid watering your Thlaspi africanum from above, as this can promote the spread of the disease. Use a fungicide if the disease is severe.
• Root Rot - Overwatering or poor drainage can cause root rot, which can lead to the plant wilting and dying. To prevent root rot, make sure the soil drains well and do not overwater. If the disease is already present, you can try to salvage the plant by repotting with fresh, well-draining soil and removing any affected roots.

Pest Management

Thlaspi africanum Burm.f. is relatively pest-resistant. However, some pests that may affect this plant include:

• Aphids - These small insects can feed on the sap of the plant, causing yellowing or wilting leaves. To manage aphids, try spraying the plant with a strong stream of water to dislodge them or use an insecticidal soap or oil.
• Spider Mites - These tiny pests can cause yellowing, wilting leaves, and webs on the plant. To manage spider mites, try spraying the plant with a strong stream of water, or use an insecticidal soap or oil.
• Caterpillars - Caterpillars can chew on the leaves of the plant, causing holes and damage. To manage caterpillars, try handpicking them off the plant or use a natural insecticide containing Bacillus thuringiensis.
