All things change, nothing is extinguished…  There is nothing in the whole world which is permanent.  Everything flows onward; all things are brought into being with a changing nature; the ages themselves glide by in constant movement. 

–Ovid, Metamorphoses, First Century

The only constant we can ever count on in this world is change, and there is no better place to illustrate that point than in the garden.  Unlike static architecture, gardens are evolving creations.  This is perhaps the most compelling aspect of making and tending a garden: that each new growing season brings a host of subtle changes.  We are changing daily as well.  Age brings new questions and answers to the mysteries of life.
