Foliage works better in large arrangements to fill out and shape the design, while sculptural grasses create interest and height. Other foliage, usually of year-round varieties, works better in small designs to give added detail and color. Ultimately, the foliage that you choose for an arrangement will depend on its seasonal or year-round availability.
With the exception of ruscus, year-round foliage tends to be short and so is best used for medium-sized and compact arrangements. Choose foliage such as pittosporum, bear grass, snake grass, leather leaf and black ti and green ti leaves. Salal, shown at the far left, is a dense filler best used for small designs and bouquets. The unusual silver-green leaves, pleasant scent and handsome arching stems of eucalyptus, beside it, enhance the shape of a design and add an extra flourish. The attractive feathery leaves on long curved stems of the next example, ruscus, add a delicate texture to a design.
