Two or more kinds of plants can make sheared edging more varied and interesting. On this patio, cones of rosemary mark the corners of a small rectangle of boxwood that sits on top
of a masonry square. This three-part arrangement makes an attractive base, almost like a planter, for a sculptural crepe myrtle
tree. In colder climates, dwarf Alberta spruce
could be used in place of the tender rosemary plants.
