Haircap Moss (Polytrichum commune) is one of the tallest mosses, resembling miniature pine trees. It is a robust species that can handle slightly more sunlight than other mosses and is excellent for erosion control on slopes.

Growing & Planting Guide

Prefers moist, acidic soils in partial shade. It can tolerate some direct morning sun if the soil remains damp. Plant by dividing existing clumps and pressing them into the earth.

Maintenance Tips

Keep the area free of weeds, as they can easily outcompete the moss. Water regularly to maintain its upright, forest-like appearance.
