Common Cultural : Morphological changes
(revision date: 4/30/2013)

Plant parts may significantly change as a juvenile (seedling) progresses to the adult (flowering/fruiting) stage of growth. Some of the more dramatic changes exhibited by plants include winter leaf retention of deciduous plants (oak, beech, etc.), change of leaf shape (English holly), and the transition of needle-like to scale-like leaves on junipers and false cypresses. Variegated plants may revert to their all-green form, and vice versa. Morphological changes are healthy and natural stages of plant development
