It is the creation of the more important and the less important elements in the garden. The parts of any composition should not be equal in their visual interest. Certain parts should be different, perhaps larger, of a contrasting color, form, fragrance, or texture than the rest, depending on the function of the design. Again, if too many elements are introduced the effect is lost. Emphasis can be achieved only by limiting the number of dominant design elements.
Sequence is the movement of the garden.
It is the rhythms that develop when line, form, texture, and color are changed in a consistent way to lead in a particular direction or to a point of focus. Sequence helps to connect the various design elements. Scale within the garden, as distinct from the overall scale of the garden as discussed earlier, refers to the harmony of the garden. That is, all the elements of a garden should agree in the sense they convey of the size of the whole. The actual size of an object is different from its relative scale or proportion in relation to other neighboring objects.
