Appearance:
The plant is a small, erect herb that grows up to 30-60 cm tall. It has a woody base and stems that are covered with white hairs. The leaves are simple, opposite, and elliptical with a length of 6-10 cm and a width of 4-5 cm. The upper surface of the leaves is dark green, while the lower surface is lighter in color, with prominent veins. The flowers are small and pink, with a bell-shaped corolla.
Uses:
The plant has been used in traditional medicine to treat various diseases such as fever, cough, cold, and diarrhea. The leaves and stems are pounded and used as a poultice for treating boils, wounds, and ulcers. The decoction of leaves is also used as a wash for treating skin diseases. In addition, Achyrospermum peulhorum is used as a traditional remedy for hypertension, diabetes, and malaria.
Aside from its medicinal use, the plant has no other known uses.
Light Requirements
Achyrospermum peulhorum is a shade-loving plant that requires filtered light rather than direct sunlight. It can thrive under both bright indirect light and low light conditions, making it an ideal indoor plant for homes or offices with limited sunlight.
Temperature Requirements
The growth of Achyrospermum peulhorum is optimal at temperatures between 65 to 75 degrees Fahrenheit during the day and 55 to 65 degrees Fahrenheit during the night. It can adapt to slightly higher or lower temperatures but extreme variations may lead to stunted growth or plant death.
Soil Requirements
For the best growth of Achyrospermum peulhorum, it requires well-draining soil that is rich in organic matter. The ideal pH for the soil is between 5.5 and 7.0. Soil that is too acidic or too alkaline can lead to nutrient deficiencies or toxicity that will affect plant growth.
Water Requirements
Achyrospermum peulhorum prefers consistently moist soil but will not tolerate waterlogged conditions as it can lead to root rot and other related issues. It is best to allow the soil to dry slightly between watering to prevent overwatering issues and promote plant growth.
Cultivation Methods
Achyrospermum peulhorum is a tropical plant that prefers shaded or partially shaded conditions. It can be grown in potting soil or in a well-draining mix of peat moss and sand. The plant needs an environment with high humidity, making it perfect for terrarium or greenhouse growing.
The plant should be propagated from stem cuttings. The cuttings should be taken from the healthy plant and grown in a rooting medium that is kept moist until the new growth appears. Once the roots are established, the new plant can be potted in the soil or substrate of its choice.
Watering Needs
Achyrospermum peulhorum prefers to be kept on the dryer side, but it should be watered regularly to prevent the roots from drying out. Over-watering can cause the roots to rot and lead to the death of the plant. The soil should be checked regularly to ensure that it is not waterlogged.
It is recommended that the soil is allowed to dry slightly between watering. When watering the plant, ensure that the water is distributed evenly throughout the soil, allowing it to drain completely from the bottom of the pot.
Fertilization
Achyrospermum peulhorum does not require a lot of fertilizer to grow and can thrive without it. However, a small amount of liquid organic fertilizer can be applied every four to six weeks to promote growth and improve the overall health of the plant. Over-fertilizing can lead to plant burns and a stunted growth.
Pruning
Achyrospermum peulhorum does not require much pruning, but dead or yellowing leaves should be removed as they appear to encourage new growth and maintain the appearance of the plant. Any dead or damaged stems should also be removed. It is best to prune the plant in late winter or early spring before new growth appears.
Propagation of Achyrospermum peulhorum
Achyrospermum peulhorum is most commonly propagated through seed germination and stem cuttings.
Seed propagation
To propagate this plant through seeds, collect ripe seeds when you notice the seed pods splitting open. Sow the seeds in well-draining soil, cover them lightly with soil, and keep them damp but not waterlogged. The seeds will germinate within two weeks under favorable conditions. Young plants should be kept in a shaded area until they are established, and then slowly introduced to brighter light.
Stem cutting propagation
Propagation through stem cutting involves taking a stem cutting with several leaves attached. Dip the cut end of the stem into rooting hormone and plant the cutting in well-draining soil. Keep the soil moist and regularly mist the leaves. Roots and new growth should begin to appear within a few weeks.
It's important to note that Achyrospermum peulhorum is a slow-growing plant, so patience is required with both propagation methods. With the right care and conditions, propagated plants will be sturdy and resilient.
Disease Management
The Achyrospermum peulhorum plant is generally resistant to various diseases. However, it may still be prone to fungal infections like leaf spots and blight.
To prevent fungal diseases, avoid overwatering the plant to prevent dampness, remove and dispose of infected plant parts as soon as possible, and maintain good air circulation.
If the plant gets infected, apply fungicide as a preventive measure. It is important to follow the instructions on the label of the product when applying to avoid further damage to the plant.
Pest Management
The Achyrospermum peulhorum plant is susceptible to insect pests like spider mites and mealybugs. They usually feed on the sap, causing yellow or brown spots on the leaves, and stunting growth.
Regularly check the plant for signs of insect infestation, and in case of an outbreak, use an insecticidal soap or neem oil to control the pest population. These products are often safe to use and will not harm beneficial insects like bees, butterflies, and ladybugs.
Alternatively, you can control the infestation by wiping off the insects using a damp cloth or spraying the plant with a mixture of water and dish soap. This is an effective way of getting rid of the pest population before they become too large to handle.
