To free yourself of the need to incessantly mulch, a groundcover is a good way to stabilize soil and lock out opportunistic species (weeds). The outmoded idea of using a single species as an unbroken ground cover, however, is giving way to using them to cover the ground between a diverse planting of taller species[1].

The species that you select as the ground cover will depend on climate, sun exposure, and soil moisture. Since you’re planting a rain garden, it would be safe to assume that the soil will be occasionally inundated after rain events. Many low-growing species of sedges (Carex species) or rushes (Juncus species) are adapted to moist or wet soils and part shade. Possono fornire un tappeto verde attraente e fine tra piante più alte e appariscenti.
