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
damage.

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?
Cordially,

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.
