Mild frost damage here often results in blooms looking like seersucker
fabric - puckered or crumpled instead of smooth, often the entire flower.

Independent of cultivar - seems to depend on timing of bloom development
and severity of freeze. Some cultivars are more sensitive to freeze
damage than others, but the "seersucker" look seems to show up on just
about anything. Maybe a bit more common in those with less substance??
Not sure about that tho - will pay more attention in the future.

<Lots> of opportunity to observe frost/freeze damage effects here, & my
impression re: the speckling of color that shows up some years is that
some cultivars do seem to be susceptible to that type of frost/freeze
damage. Or else that makes them more susceptible to viral _expression_.
Or who knows - but it's always the <same> cultivars here.

Just as some cultivars are more likely than others to have extra parts
in response to freeze damage.

Which implies there is some iris genetic component, even if it is viral.
