      Summary Author:  Menashe Davidson   
      
      In our apartment-garden, located in the city Rishon-LeZion, Israel, we   
      grow in containers about 100 species of plants. Annuals and perennials,   
      low plants, bushes, climbers and trees. Most of them flowering   
      ornamentals, for the  beauty of their seasonal bloom. But the most   
      prominent plant, all the yearlong and not just seasonal, is the   
      Dieffenbachia seguine plant, known as  dumb cane from the family   
      Araceae. The focal point of a dieffenbachia is the beautiful patterns   
      of the foliage, which are variegated, all year long if properly   
      cultivated.   
      
       Variegation is the appearance of differently colored zones pf a   
      plants’ leaves. Dieffenbachia leaves, are generally large and ovate,   
      have irregular areas of splotches with lighter green, yellow or even   
      cream color. In the first picture we already see the patterns appear on   
      the eternal juvenile leaf of the vegetative bud. It then maintains this   
      same appearance regardless of the plants’ age (second picture).   
      
      The variegation is caused by mutations that affect  chlorophyll   
      production. This is 'built' into the plant DNA. Note that in some   
      portions of the leaf tissues there’s a lack of chlorophyll pigments.   
      The purpose of variegation is still a matter of debate. Regardless,   
      gardeners enjoy harnessing the pattern traits that produce the most   
      desirable, eye-catching plants.
