My parents house was a traditional home that had the typical Japanese garden in the back with various different trees, plants and many seasonal flowers. I grew up playing around our Japanese black pine, Japanese plum, loquat (Eriobotrya japonica) and pomegranate trees, all the while enjoying the azaleas, camellias and many other flowers that my father nurtured with so much love and dedication. I also remember that we had flowers that were originally introduced in Japan from foreign countries, such as Amaryllis (Belladonna Lily), roses, daisies, and dahlias. So while our garden was very Japanese in style, I can now see how it was more like a display of universal nature.
Actual lines are very obvious. The eye can easily follow the design to its height and width. Actual lines sets up the skeleton of the design. Actual line flowers can be curving and flowing within the design. Implied lines in floral design provide a pathway for the eye to follow but no actual line flowers are there. Although carnations are not line flowers per say, if they are cut one taller than the other that can create a line effect. Greenery can also create a line effect. As our eyes connect the upward graduating carnations we see a line result. The third kind of line is the psychic line. This is a line that does not exist, yet we feel the line outcome. Psychic designs are made by placing flowers in a manner that directs the eye up and throughout. Two tall birds of paradise can be placed high in an arrangement, while all other flora materials are rather short and to the base. The two tall birds of paradise create a visual line and bring the visual path upward. Many oriental designs use this technique.
