Re: Freaks -- Weather Damage

I agree with this observation. Iris growers as a group seem irrationally
determined to blame every cultural or environmental problem on the
cultivar that happens to be victim to it once or twice. Bearded irises
are actually a sadly homogeneous group of plants, genetically speaking.
When it comes to random peculiarities in growth, such as bloom out,
extra petals, or stunted stalks--not to mention disease susceptibility,
the scientist in me wants to see some very carefully collected evidence,
analyzed statistically, before blaming the cultivar.

Happy irising, Tom.
