The low-growing, shrubby evergreen varieties of Euonymus, such as Euonymus fortunei 'Emerald 'n Gold', zones 5 to 9, and Euonymus fortunei 'Emerald Gaiety', zones 4 to 9, have been great favorites for many years as ground cover plants.
New to the market and set to become a great favorite is Euonymus japonicus 'Pierrolino', hardy to zone 6. Pierrolino is a compact, dense and bushy evergreen shrub that comes alive in spring with rounded white to mottled white leaves.
