“Though there are exceptions in all species, many useful border plants — {{w|Aster (genus)|aster}}s, {{w|dahlia}}s, members of the {{w|Asteraceae|daisy family}}, {{w|penstemon}}s — have foliage that is at best undistinguished, at worst down right ragged. Careful placing of foliage plants will disguise these shortcomings very well. They bring an outstanding variety of form to mixed plantings: fat rounded leaves of {{w|bergenia}}, feathery plumes of {{w|Artemisia (plant)|artemisia}}, stiff sword shapes of {{w|phormium}} and {{w|yucca}}.”
