Overview

Pleurozium spp. is a genus of pleurocarpous mosses in the family Hylocomiaceae, represented chiefly by the widespread Pleurozium schreberi. It forms loose to dense carpets across the floor of boreal and northern temperate forests, on heathland, and over peat, growing 5-15 cm (2-6 in) tall and spreading indefinitely into mats. The stiff, reddish stems are a reliable feature, branching in a regular pinnate pattern and bearing concave, oval leaves 2-3 mm long that overlap to give the shoots a plump, rounded outline. Foliage is yellow-green to golden-green and remains photosynthetic through the year. As a moss the genus has no roots, flowers, or seeds; water and nutrients are absorbed directly across the surface, and anchorage comes from thread-like rhizoids. Spore capsules are produced only occasionally, raised on short reddish stalks. Pleurozium spp. is a major component of ground cover in spruce and pine forests across the circumboreal zone, where its mats insulate the soil and influence seedling establishment. One limitation in cultivation is its need for consistent humidity and cool, shaded conditions; the mats dry and brown in prolonged heat or direct sun, recovering only when moisture returns.

Native Range

Pleurozium spp. has a circumboreal and circumtemperate distribution across the Northern Hemisphere, spanning North America, Europe, and northern Asia, and also occurs in parts of the Southern Hemisphere. It is common in boreal coniferous forests, on heaths, and in bogs.

Suggested Uses

Grown as a ground cover and feature in shaded moss gardens, woodland borders, and Japanese-style plantings. Used to green over peat beds, log surfaces, and the floor of cool, damp courtyards. Also gathered traditionally as a liner and packing material.

How to Identify

Look for stiff, distinctly red stems carrying neatly pinnate branches, a combination that gives Pleurozium spp. its common name of red-stemmed feathermoss. The concave, blunt leaves are pressed somewhat closely so each shoot looks rounded and plump rather than flattened. Unlike many companion mosses, the branches lie largely in one plane and the shoot tips are pale and rounded.

Bloom Information

As a moss, Pleurozium spp. does not flower; it reproduces by spores and by fragmentation of its stems. Spore-bearing capsules form only sporadically, lifted on short red stalks in summer, and many colonies persist for years without producing them. Most spread in gardens and in the wild comes from vegetative growth of the mat.

Care & Maintenance

Care Guide

Pleurozium spp. grows in cool, humid, lightly shaded sites on acidic substrates such as peat, leaf litter, humus, or decaying wood, at a pH around 4.5 to 6.0. It needs steady surface moisture and tolerates no fertiliser or lime, both of which damage the mat. Establishment is achieved by laying fragments or whole pieces onto firmed, weed-free ground and keeping them moist until the rhizoids attach. The genus withstands extreme winter cold but browns under hot sun and drought, reviving when humidity and rainfall return. Foot traffic and accumulated leaf fall both thin the mats. No feeding is required.

Pruning

Mosses are not pruned. Maintenance consists of clearing fallen leaves and debris that would otherwise smother the mat, and lifting and re-pressing pieces to fill gaps. Encroaching grasses or seedlings are removed by hand.
