Quite right about copper toxicity to many plants but Darlingtonia is
remarkably tolerant of heavy metals in its habitat ( see 'Serpentine and Its
Vegetation' By Brooks 1987). and while I not sure of the forms of copper that
might present in A.C condensate, I expect it would kill your moss but not
your D.californica.
