Hello Arnold,

Well, that sounds like jacket weather to me for summer nighttime
temperatures.  Our summer nights tend to run more to 80-85, with cool nights
falling into the 70s.  It's my own personal belief that those long weeks of
warm night temperatures are the single most limitating factor on being
successful with a lot of plants.  Garden allium, e.g., will not survive our
summers.  It will thrive the rest of the year, but won't return in the fall
after going through a summer.  Lots of areas that get our daytime highs,
cool off at night.  But I found to my sorrow that even some desert plants
won't make it here and I think it's because the nights don't cool down.
Seems a lot of plants don't like long stretches without a break.  Oddly,
what can do really well here are tropicals.  They tend to thrive on the warm
nights.  The catch, of course, is that it's dry with low humidity and water
is expensive.  That limits growing tropicals to just the occasional pocket
and working hard at keeping that pocket damp and keeping the humidity up
around the plants.
