In permaculture systems we try to keep the ground permanently covered with mulch, green crops (green manure) or perennial ground cover plants. This mimics nature, which rarely leaves any bare soil. Bare soil invites weeds and causes erosion from wind and rain. We offer a selection of ground cover plants suitable for planting as vege companions, under trees, or in tricky sites such as eroded hillsides. Some are suited to dry, sunny sites, others are good for damp shade. Please note that many ground cover plants spread easily – that is their forte, but some may be invasive depending on the climate and soil type, so choose carefully.
