FYI for new list members, there is a zone system for summer-dry climates on the wiki: http://pacificbulbsociety.org/pbswiki/index.php/… Even that is just an approximation, of course, since it doesn't take into account things like soil type and moisture from fog. But it's a starting point to understanding the native climate of a particular summer-dormant bulb.
