Unity is obtained by the effective use of components in design to express the main idea through consistent style. Unity can be achieved by using mass plantings of one plant and repetition using the same plant in different areas.  Each area of the landscape must complement the central garden theme and blend together.

Balance in garden design refers to the equilibrium or equality of visual attraction.

Transition is a gradual change. Transition can be obtained by the arrangement of objects with varying textures, forms, or sizes in logical sequential order.

Proportion refers to the size of items in the landscape design in relation to each other and to the design as a whole. One large towering oak tree may compliment an office building, but would probably dwarf a single story residence.

Rhythm is achieved when the elements of a design create a feeling of motion which leads the viewer’s eye through or even beyond the designed area. Curved walkways and curved plants in a bed create a feeling of motion.

Focalization involves the placement of garden features in specific areas to create interest. Features may include plant containers, various garden art and trellises, and arbors.

Continuity is achieved by using all the design principles listed above
