In floristry the ODD’s win over the EVEN. The Rule of Thirds are applied to all types of art; floral, architecture, graphic design, photography, etc.
In floral design, flowers and objects including vases are typically grouped in odd numbers and are usually emphasized in an arrangement. It is not only easier to design using odd numbers, 3,5 & 7 but is visually more pleasing than using even; 2,4 &6. One of the 6 Principles of Floral Design is Proportion which brings me to talk about the Golden Mean. Technically the ratio is 1.1688 and is simplified to a 2:3 ratio. Example: 2 to 3, 3 to 5 and 5 to 8 are all about the same ratio; therefore are equally pleasing. The Golden Rule can determine how high flowers should be and the width of an arrangement. A 3 to 5 ratio could apply to this, 3 being the container, 5 the flowers and 8 totaling the arrangement. This rule can also apply to WHERE a floral arrangement is placed. For instance instead of centering an arrangement in the middle of a table, off center it, placing in the upper right or left hand corner. This division is more pleasing to the eye and natural.
The sequence of the Golden Rule begins with 0 and 1. All you have to do is add the last two numbers together to get the next number in the sequence. Example : 0+1=1, 1+1=2, 1+2=3, 2+3=5, 3+5=8, and so on. The series becomes : 1,2,3,5,8,13,21,34,55,89,144 etc.
The Golden Mean is a Greek rule of proportion referring to the division of a line that is the most pleasing to the eye. Through this we as artists and designers can create a harmonious, proportionate and well balanced floral creations. Equal division in floral design can be straight forward and sometimes can add lack of interest. Unequal division creates a lack a harmony and the Golden Mean is within good proportion, is appealing to the eye and draws others into it.
