Common Names
Monelasmum viride Tiegh. is commonly known by the local name "verdillo" in Ecuador. In some regions, this plant is also called "tapaculo" or "azulillo".
Uses
Monelasmum viride Tiegh. is widely used in traditional medicine due to its antibacterial and antifungal properties. The leaves and bark of this plant are used to treat wounds, ulcers, and skin infections. The plant extract is also used as a natural colorant for fabrics and textiles.
In addition to its medicinal properties, Monelasmum viride Tiegh. is used in the reforestation of degraded areas. The plant's ability to tolerate shade and its rapid growth make it an ideal species for restoration of cloud forests.
General Appearance
Monelasmum viride Tiegh. is a small to medium-sized shrub that can grow up to 3 meters high. This plant has an erect stem with several branches. The leaves are simple, opposite, and elliptic to ovate in shape. The plant produces small, white to pink, four-petaled flowers that are up to 1 cm in diameter. The fruit is a reddish-brown capsule that contains numerous black seeds.
The leaves of Monelasmum viride Tiegh. contain a milky sap that is used medicinally and as a dye. The sap is toxic if ingested and can cause skin irritation in some people.
Light Requirements
Monelasmum viride Tiegh. thrives under moderate to bright light. It needs around 6-8 hours of sunlight per day. Plants grown under low light conditions tend to have elongated and thin stems and smaller leaves.
Temperature Requirements
The ideal temperature range for Monelasmum viride Tiegh. is between 18°C to 26°C. It cannot tolerate extreme cold or heat. During the winter season, it should be kept in a warm and sheltered place to avoid exposure to extreme cold. In contrast, during the summer season, it should be kept in a place that is shaded from direct sunlight to avoid exposure to extreme heat.
Soil Requirements
The plant requires a well-drained soil that is rich in organic matter, with a pH range between 6.0 to 7.5. Heavy clay soils should be avoided, as they can lead to poor drainage and root rot. A potting mix that contains peat moss, perlite, and vermiculite is ideal for Monelasmum viride Tiegh. It also prefers slightly moist soil, so it is recommended to water it once the top inch of soil feels dry to the touch.
Cultivation Methods
Monelasmum viride Tiegh. is a moderately sized tropical plant that is commonly found in Southeast Asia and South America. It is usually grown as an ornamental plant in gardens, parks, and indoors. To cultivate this plant successfully, it is essential to provide it with the optimal temperature, light, soil, and water requirements.
The plant thrives in warm, humid environments, with temperatures ranging from 20 to 30 degrees Celsius. It requires partial shade or indirect sunlight, with protection from the direct sun. The ideal soil for cultivation should be loamy, well-draining, and rich in organic matter.
Propagation can be achieved through seeds or stem cuttings. It is recommended to sow the seeds in well-drained soil and keep the soil moist until germination. Stem cuttings should be taken in the early morning, dipped in rooting hormone, and then planted in moist soil or water until roots develop.
Watering Needs
Monelasmum viride Tiegh. requires moderate watering, with the soil kept consistently moist, but not waterlogged. The frequency of watering depends on the temperature, humidity, and soil conditions. It is crucial to keep the soil moist during the growing season, but reduce watering during the dormant period to prevent root rot.
If grown in a container, ensure the pot has adequate drainage holes to prevent standing water. It is recommended to water the plant in the early morning or late evening to minimize water loss through evaporation.
Fertilization
Monelasmum viride Tiegh. benefits from regular fertilization with a balanced fertilizer, containing equal amounts of nitrogen, phosphorous, and potassium. Fertilization should be done during the growing season, typically every two to four weeks, depending on the type of fertilizer used.
Organic fertilizers such as compost or manure can also be used to improve soil health and fertility. However, overfertilization should be avoided, as this may cause fertilizer burn, root damage, or reduce plant growth and development.
Pruning
Monelasmum viride Tiegh. should be pruned regularly to promote bushy growth and remove dead or diseased leaves. Pruning can be done throughout the year, but it is best to avoid pruning during the dormant period.
The plant can be pruned using clean, sharp shears, and the cuts should be made just above a leaf node or joint. Regular pruning also helps to control the plant's height and shape, making it more attractive as an ornamental plant.
Propagation of Monelasmum viride Tiegh.
Monelasmum viride Tiegh. can be propagated through various methods. Some of the common methods of propagation are:
Seed propagation:
Monelasmum viride Tiegh. produces seeds that can be used for propagation. The seeds require a well-drained soil mix with a pH range of 5.5 to 6.5. The seeds must be sown on the surface, and a thin layer of soil must be spread over them. The soil must be moistened regularly, and the seeds must be placed in a warm and humid environment for germination.
Cuttings:
Monelasmum viride Tiegh. can be propagated by cuttings. The cuttings must be taken from the stem tips of the plant during the active growing season. The cuttings must be about 6 inches long and must be taken with a clean, sharp tool. The cuttings must be dipped in a rooting hormone powder and planted in a well-draining soil mix. The soil must be watered well, and the cuttings must be kept in a warm and humid environment for rooting.
Division:
Monelasmum viride Tiegh. can be propagated through division. The plant must be dug up, and the roots must be carefully separated into small clumps. Each clump must have at least one healthy stem attached to it. The clumps must be planted in well-draining soil mix. The soil must be moistened, and the new plants must be kept in a shaded area for a few days until they become established.
These are the various methods of propagating Monelasmum viride Tiegh. that can be used by growers to propagate new plants.
