Traditionally, Italian gardens are "green' with few flowers. The plants are mainly evergreens, manicured into geometric hedges or topiaries. However, the evergreen foliage of these shrubs or trees offers a wide array of shades, ranging from gray to silver, bronze to gold, or simply from light to dark green. They are displayed in a variety of shapes that bring interest and energy such as clipped topiary, balls, or cones. Italian cypress (Cupressus sempervirens), boxwoods (Buxus spp.), and junipers (Juniperus spp.) are commonly used to delineate the various parts of the garden. Other green plants are massed within the borders of the geometric beds.

Not to forget pergolas smothered with fragrant climbers such as jasmine, wisteria, and roses. Filling the air with their wonderful fragrance, they are also underplanted with scented herbs such as rosemary or lavender.

To achieve harmony, limit yourself to 1 or 2 shades of flower colors. For instance, pick bright red geraniums (Pelargonium) for their stunning contrast against the greenery.
