Common Names
Erlangea pauciseta is known by several common names depending on the region. These names include the stinkwort, false yellowhead, small grey erlangea, and blanketweed.
Uses
Erlangea pauciseta has many medicinal uses due to the presence of chemical compounds such as terpenoids, flavonoids, and alkaloids. They have anti-inflammatory, anti-fungal, and antibacterial properties, which are useful in treating various ailments such as bronchitis, respiratory infections, and skin infections. Additionally, the plant is used by traditional healers to treat malaria, parasitic infections, and fever.

The leaves of the plant are also used as green manure to improve soil fertility.
General Appearance
Erlangea pauciseta is a perennial plant that can grow up to 60cm tall. It has an erect stem, which is light green to brown in color and covered with short hairs. The leaves are narrow, elongated, and have a greyish-green color. The flowers are yellow and appear in small clusters at the top of the stem, with each flower having a distinct smell. The plant blooms from October to May, and the fruits resemble seeds that are dispersed by the wind.
The plant grows well in disturbed areas such as cultivated fields, pastures, and along road sides. It is tolerant of drought and prefers sandy soils with good drainage.
Light Requirements
Erlangea pauciseta prefers to grow in full sun to partial shade. It can tolerate a range of lighting conditions but requires at least 6 hours of direct sunlight per day to thrive.
Temperature Requirements
The plant is best suited for warm temperatures. It can tolerate temperatures up to 35°C but prefers temperatures between 20°C and 30°C. Temperatures below 10°C can stunt its growth or even cause it to wither.
Soil Requirements
Erlangea pauciseta prefers well-drained soils rich in organic matter. It grows best in sandy or loamy soils with a pH range of 5.5 to 7.5. The plant cannot tolerate waterlogged soils and needs good drainage to prevent root rot. It also benefits from occasional fertilization with a balanced fertilizer to promote growth and flowering.
Cultivation Methods
Erlangea pauciseta is a perennial plant that can be cultivated either indoors or outdoors. If choosing to grow it outdoors, make sure to plant it in a well-drained soil and in a location that receives plenty of sunlight. It can also tolerate partial shade.
If growing Erlangea pauciseta indoors, select a pot that is at least 6 inches deep and wide enough to provide ample space for growth. Use a soil mix that is well-draining and rich in nutrients.
Watering Needs
Erlangea pauciseta requires moderate watering. Water around the root zone and avoid getting the leaves wet. Water the plant when the soil is dry to the touch. Also, make sure there is no standing water around the plant as it can lead to root rot.
Fertilization
The plant requires fertilizer during the growing season to promote proper growth and blooming. Fertilize with a balanced fertilizer, applying it every two weeks. Be sure to follow the recommended concentration guidelines as excess fertilizer can harm the plant.
Pruning
Pruning Erlangea pauciseta is not necessary. However, if the plant becomes leggy, you can trim the stems by 1/3 of their length to encourage bushier growth. Deadheading can also promote more blooming. Pinch or cut off the spent flowers as soon as they appear.
Propagation of Erlangea Pauciseta
Erlangea pauciseta is a stunning perennial that belongs to the family Asteraceae, and it is a native of Ethiopia. The plant is widely grown in gardens and homes due to its beautiful leaves and flowers. Propagation of Erlangea pauciseta can be easily achieved through vegetative propagation or by sowing seeds.
Propagation by Vegetative Means
Vegetative propagation of Erlangea pauciseta is quick and easy. It involves using vegetative parts of the plant such as cuttings, divisions or root suckers to produce new plants. Cutting is the most common method used for propagation. Follow the steps below for successful propagation:
- Take cuttings from the mother plant, ensuring you choose healthy stems that are free from disease and pests.
- Cut a 10 to 15cm long stem from the parent plant and remove the lower leaves to expose the nodes.
- Prepare a pot with a well-draining soil mix made of equal parts of perlite, peat moss, and vermiculite.
- Dip the cutting in rooting hormone then plant it in the potting mix, ensuring that the nodes are submerged in the soil and the cutting is well secured.
- Water the cutting thoroughly and keep it in a warm and bright area but away from direct sunlight.
- The cutting should root in about 2 to 3 weeks and in about 2 to 3 months, it will be ready for planting in its desired location.
Propagation by Seeds
Sowing seeds is another propagation method for Erlangea pauciseta. However, it requires patience and keen attention to detail. Follow the steps below for successful propagation:
- Collect mature seeds from the mother plant. The seeds are usually light brown in color.
- Clean the seeds by removing all the chaff and store them in a dry and cool place.
- Prepare a tray or pot with a well-draining soil mix made of equal parts of perlite, peat moss, and vermiculite.
- Sprinkle the seeds over the soil surface, ensuring you space them apart to avoid overcrowding.
- Cover the seeds with a thin layer of the soil mixture and water them gently to avoid washing them away.
- Keep the tray or pot in a warm and bright area, ensuring you maintain the soil moisture level by watering the seeds regularly.
- The seedlings should germinate in about 2 to 3 weeks and in about 4 to 5 months, they will be ready for planting in their desired location.
Disease and Pest Management for Erlangea pauciseta (O.Hoffm.) S.Moore
Erlangea pauciseta (O.Hoffm.) S.Moore is a beautiful and unique plant that belongs to the Asteraceae family. While it is known for its beauty and adaptability, it is also vulnerable to several pests and diseases that can damage or even kill the plant. As a responsible gardener or farmer, it is important to be familiar with these threats and take steps to manage them effectively.
Common Pests
Several pests can affect Erlangea pauciseta, the most common of which are thrips, spider mites, and aphids. These pests are small, and they feed on the leaves of the plant, causing them to wither and turn brown. They also cause stunted growth and deformation of the plant. The best way to prevent pest infestation is by ensuring that the plant is regularly inspected and any infestations are immediately treated.
One effective way to manage pest infestations is by using organic insecticides such as neem oil, insecticidal soap, and garlic spray. These natural remedies are helpful in controlling pests without harming the plant or the environment. Additionally, beneficial predators such as ladybugs, lacewings, and parasitic wasps can be introduced to the garden to control pests.
Common Diseases
Erlangea pauciseta is also prone to several diseases such as rust, powdery mildew, and leaf and stem blight. These diseases are caused by fungi and can spread rapidly, causing significant damage to the plant. Rust, for example, is characterized by rusty-orange spots on leaves while powdery mildew appears as white patches on leaves.
To control the spread of fungal diseases, infected leaves and stems should be removed and discarded. The plant should also be watered at the base to avoid splashing soil onto the leaves, which can facilitate fungal growth. Additionally, using fungicides such as sulfur, copper, and potassium bicarbonate can help manage the spread of fungal diseases.
Prevention
Prevention is key when it comes to managing pests and diseases that affect Erlangea pauciseta. The plant should be kept healthy by providing it with adequate water, fertilizer, and sunlight.
