A few additions to Lou's  list of variables.

I find that the best way for me to find variables is to travel and be  
startled by climate differences compared to my maritime home.
A few that must have an effect on plants:

the intensity of winter light in Arizona
fog dripping off plants in summer in Tofino
incredible night and day temperature differences in the Karoo - from  
minus 8 to plus 22 in one 12 hour period
