Benefits of Irish moss
Foot Traffic Friendly: Most groundcovers are utilized in landscape areas away from heavy traffic or in conjunction with stones or pavers to create walking areas. However, irish moss can take light or even moderate foot traffic.
Guards against weeds: The dense and weaved green carpet formed by Irish moss crowds out most weeds. Irish moss also allows your soil to retain more moisture, reducing overall water usage.
Stability for Slopes: Irish moss is a low maintenance option for slopes, the roots help control soil erosion from heavy winter rains.
Perfect for a serene and bare-foot friendly path, Irish moss is also an excellent plant for rock gardens, where it forms a soft carpet of evergreen color amidst the gruff boulders. It is well suited for container plantings, where it will slowly creep to cover open soil. Growing just about 1-2 inch tall and boasting pretty white flowers, Irish moss is a nearly perfect plant for all gardens.
