Overview
Orthothecium rubellum (Mitt.) Kindb., also known as Red-stemmed Feather moss, is a species of moss that belongs to the family Brachytheciaceae. It is a small-leaved and mat-forming plant that is commonly found in North America, Europe, and Asia. This species prefers to grow in damp, shady places, such as bogs, fens, and wet meadows.
Description
Orthothecium rubellum has a distinctive red stem, which distinguishes it from other feather mosses. The stems can grow up to 8 cm long, and are covered with short and branched shoots. The leaves are lance-shaped and have sharp and pointed tips. The leaf color ranges from yellowish-green to greenish-brown, and they are arranged in a spiral pattern around the stem. This species reproduces both asexually and sexually, by the production of spores.
Uses
Orthothecium rubellum has several uses in the landscaping industry. It is often used as a ground cover in shady areas, such as under trees or along streams. It is also used to retain soil moisture and prevent soil erosion. In addition, this species is commonly used in terrariums and as a decorative plant in floral arrangements.
Orthothecium rubellum also has some medicinal properties. The plant contains compounds that have been found to have antibacterial and antioxidant effects. The moss has been used in traditional medicine to treat various ailments, such as sore throats, chest congestion, and rheumatism.

Orthothecium rubellum is a small and red-stemmed moss that is native to North America, Europe, and Asia. It is commonly used as a ground cover in shady areas and as a decorative plant in floral arrangements. In addition, the moss has some medicinal properties and has been used to treat various ailments in traditional medicine.
Light requirements
Orthothecium rubellum typically thrives in low-light environments, such as shaded or partially shaded areas. However, it can tolerate moderate sunlight as well. It is important to avoid exposing the plant to direct sunlight for extended periods as this may cause the leaves to dry out and the plant to wither.
Temperature requirements
The ideal temperature range for Orthothecium rubellum is between 5°C to 20°C (41°F - 68°F). It grows well in cool and moist environments such as forests, cliffs, and shaded rocks. During hot and dry summers, the plant becomes dormant and resumes growth in the cooler months.
Soil requirements
Orthothecium rubellum prefers acidic soils with a pH range of 4.5 to 6. It thrives in well-draining soils, such as loam, sand, or rocky soils. The plant is adapted to rocky environments and can grow on shallow soils present on rocks and cliffs. It is also tolerant of poor soils that lack nutrients, making it a suitable option for landscaping in rocky or gravelly areas.
Cultivation Methods
The Orthothecium rubellum is a hardy and low-maintenance plant that prefers shady or partially shady spots. It can be grown in USDA zones 4-9, but it thrives best in areas with mild temperatures.
The plant can grow in various soil types like sandy, loamy, or clay soils. It does not require much soil preparation before planting, as it prefers a well-draining and moist soil. Use a low-nutrient soil mix with perlite and sand to ensure adequate drainage when planting in pots.
Watering Needs
Orthothecium rubellum is a moisture-loving plant that requires regular watering to keep the soil moist but not waterlogged. This plant can be grown in standing water, but it is advisable to provide enough drainage to prevent the roots from rotting.
During the growing season, water the plant at least twice a week and increase the frequency during the hot summer months. Reduce watering during winter, as the plant goes dormant at this time.
Fertilization
To promote healthy growth and development, Orthothecium rubellum requires moderate fertilization. Use a slow-release or organic fertilizer in the planting hole or mix with the soil when transplanting. Provide additional fertilization every 6-8 weeks during the growing season with diluted liquid fertilizer. Avoid over-fertilizing the plant, which can lead to lush foliage but at the expense of flowering.
Pruning
Pruning is a crucial aspect of the cultivation of Orthothecium rubellum, as it promotes bushier growth and more abundant flowering. The best time to prune the plant is in spring, just before the start of new growth. Remove any dead, diseased, or damaged branches to give the plant a tidy appearance. Pruning also encourages new growth and flower production.
Propagation of Orthothecium rubellum
Orthothecium rubellum can be propagated using two main methods: spore propagation and vegetative propagation.
Spore Propagation
The easiest method to propagate Orthothecium rubellum is through spores. Spores are tiny reproductive cells produced by the plant and are found in the sporophyte stage. Spores can be collected from mature plants and then sown in nutrient-rich soil to produce new plants. To collect the spores, mature plants can be placed in a plastic bag to allow the spores to drop, which can then be collected and sown. Once the spores have been collected, they can be sown on a layer of nutrient-rich soil and kept moist until they germinate. The ideal temperature for spore germination is between 15-20°C.
Vegetative Propagation
Vegetative propagation is another way to propagate Orthothecium rubellum. This method involves taking cuttings from mature plants and then rooting them to produce new plants. The cuttings should be taken from healthy plants during the growing season. Cuttings should be around 2-3 cm long and taken from the top of the plant, just below a node. Once cuttings have been taken, they should be placed in a rooting medium such as perlite or vermiculite. Cuttings should then be kept in a warm, humid environment with temperatures around 20-25°C. In a few weeks, the cuttings should start to root, and new plants will emerge.
Overall, Orthothecium rubellum can be easily propagated using either spore or vegetative propagation methods. By following these simple steps, individuals can produce new plants, helping to spread the beauty of this species.
Disease and Pest Management for Orthothecium rubellum
Orthothecium rubellum is generally a hardy plant that is not prone to serious diseases and pest infestations. However, like all plants, it can be affected by environmental stress, pathogens, and pests. Here are some common diseases and pests that can affect Orthothecium rubellum and ways to manage them:
Fungal Diseases
Orthothecium rubellum can be susceptible to several fungal diseases, including:
- Anthracnose: This disease causes brown or black lesions on the leaves. To manage it, remove infected leaves and dispose of them properly.
- Rust: Rust causes orange or yellow pustules on the leaves. It can be managed by removing infected leaves and avoiding overhead watering.
- Pythium root rot: This disease causes the roots to rot, leading to wilting and yellowing of the leaves. To manage it, avoid overwatering and improve soil drainage.
Bacterial Diseases
Bacterial diseases are less common in Orthothecium rubellum but can still occur. These include:
- Soft rot: This disease causes the leaves and stems to become slimy and mushy. To manage it, remove infected plant parts and improve air circulation.
- Crown gall: This disease causes tumors to form on the stems or roots. Infected plants should be removed and disposed of properly.
Pests
Orthothecium rubellum can also be affected by pests, such as:
- Aphids: These small insects suck sap from the leaves, causing them to yellow and distort. Aphids can be managed through natural predators, such as ladybugs, or by spraying with insecticidal soap.
- Spider mites: These tiny pests can cause yellowing and stippling of the leaves. They can be managed by keeping the plant well-hydrated and by spraying with insecticidal soap.
- Caterpillars: Caterpillars can chew on the leaves and stems of Orthothecium rubellum. They can be managed by picking them off by hand or by using Bacillus thuringiensis (BT) spray.
By being vigilant and practicing good gardening practices, such as proper watering and fertilization, you can help prevent diseases and pests from affecting your Orthothecium rubellum.
