We got warm weather and freeze last year
here. It didn't hurt many of the tall beardeds if I
remember correctly but I
got a lot of damage on my standard dwarf
beardeds. We might be heading for the same thing again here as well,
it has been really nice for the last month or so
and it is only early May! It is very possible to get freezing
and even snow before the end of May.

Two different types of damage tho - freeze/thaw is earlier in the season
than heat wave/freeze. The first heaves, the second kills. Both cause
injury, which can lead to rot.
But lush growth, during the peak
growing time of the plant, as it's
trying to send up bloomstalks (or after
they have already started) seems
particularly susceptible to death - all
the energy reserves went into
that new growth and there's nothing left for
repair or new growth.
This far south, right about where the winter jet
stream 'lives' on
average, we can have weeks of good iris growing weather
(i.e., highs in
the upper 70s, even near 90) in the middle of the winter
if the jet
stream wobbles north for a while. Then it can turn into mid
again, with lows in the single digits.
The southern jet
stream seems to be wobbling farther north the last few
the Tennessee experience with Kentucky and even
farther north. And it sure
wobbled farther south than usual this spring!
> That type of weather
is the real problem; freeze/thaw happens here a lot in early spring.
