A living mulch is a type of low-growing ground cover that blankets soil like a mulch. In this garden, golden creeping jenny (Lysimachia nummularia ‘Aurea’) is the living mulch. Other plants that work well as living mulches include alpine strawberry, low juniper, vinca vine or short mints like Corsican mint. Be careful with living mulches that root along stems as they grow. These types of plants can easily become invasive and even try to overgrow lawns.
