Appearance
Calliergon mosses have a sprawling habit and can form dense mats up to 10cm in height. The stems are typically reddish-brown and can be up to 30cm long. The leaves are lance-shaped and are arranged in two rows along the stem. They are usually 2-4mm long and have a sharp, pointed tip. The leaves are typically green in color, but can be tinged with red or brown. The sporophytes are borne on short stalks and have a cylindrical capsule that is covered by a hood-like structure called a calyptra.
Care Guide
Calliergon mosses require a moist environment to thrive. They prefer bright, indirect light and should be kept out of direct sunlight. The soil should be kept moist but not waterlogged, and should be well-draining to prevent root rot. Fertilizers are not necessary, but a light application of diluted liquid fertilizer can be applied during the growing season. Calliergon mosses are hardy in USDA hardiness zones 4-8.
Common Pests & Diseases
Calliergon mosses are relatively pest-free, but can be susceptible to fungal diseases such as powdery mildew and rust. They can also be affected by bacterial diseases such as leaf spot. Overwatering can lead to root rot, which can be fatal to the plant.
Habitat
Calliergon mosses are commonly found in wetlands, streams, and other moist habitats. They prefer acidic soils and can tolerate low nutrient levels. They are often found growing alongside other mosses, ferns, and liverworts.
