the natural growth rate inherent in a plant growing in  climates that
tend to promote growth at the wrong time. But I doubt any iris is immune
to the effects. Depending
 on the stage of growth and the timing of the freeze, I  would expect
any to exhibit the effects when they are  caught......... I've pretty

My observations coincide with yours for a lot of cultivars, but not
all.  There is a subset that gets frozen out (doesn't bloom at all) if
it gets hit at the wrong (right?) time, but will otherwise bloom
consistently at about the same height every year that it blooms.
Sometimes these cultivars will even produce stalks the 'normal' height
but with withered, brown buds.

I wonder if this is a pallida trait - certainly this is how the common
pallida in this area behaves....all or nothing.  A short list of "all or
nothing' stalk cultivars here: NIGHT GAME, DUSKY CHALLENGER, I. pallida,
MEMORIES is like this also - but I'm not positive.  It usually doesn't
give me much spring bloom (neither does pallida).
