 The seedlings germinated, then got frozen. They were all like little popsicles. 

When thawed out, proceeded to grow without missing a beat or showing any damage.

Subject: [iris] HYB germination - Fogbound etc

Not sure if this will be of interest...

Also meant to add to Chuck's comment about seedlings germinating well 

after being accidentally frozen - seedlings can germinate in the outdoor 

pots here after hard freezes, sometimes the next day, if temperatures 

don't get below the mid 20s or so.  Never have seen seedlings germinate 

immediately after a dip to the teens or lower.  If I weren't trying to 

add genes from cultivars selected in climates better suited to irises 

(not such extremes in erratic temperature), I wouldn't put as much 

effort into protecting them from severe cold following long warm spells.
