Good ground cover doesn't always have to mean creating a high maintenance border or flowerbed. Low-growing plants such as Microbiota decussata, an easy-to-maintain, evergreen conifer, provide excellent, year-round coverage and require little effort. What's more, Siberian Carpet Cypress can be grown on steep slopes and in other problematic but sunny areas. Wherever it's planted, Russian Arbor-Vitae will add interest to the garden, especially when it turns an attractive bronze-purple colour in the winter. Height: 1m (3'3). Spread: 1m (3'3).
