In very simplistic terms, the stomata moisture, like water in a household 
water pipe, expands when frozen and if this is heated up by sunshine which 
acts through the frost as a magnifying lens is the 'bit' that does most 

Hi Gang,

Iain described how to protect plants that might have been exposed to mild 
frots, plants that might even have some frozen water in the leaves.

I'm forever amazed anew by plants and their clever ways. how they know when 
to bloom, or when to become dormant, or how they are such amazing chemical 
factories.  I've heard about the frost and sunlight problem before, but 
never really understood how it works.  Can anyone explain what goes on when 
sunlight damages frosted leaves?

P.S.  One more Crinum is in bloom this fall; flowers can just pop up when 
you don't look for a day or two.  This unknown plants is a foundling that 
resembles (but is not)  'River Forks'.   In turn, 'River Forks' is a 
beautiful plant; I sometimes wonder if it is C. amoenum.
