Greetings.
"Pineappling" is a term for a condition whose origins are mysterious but whose
symptoms are distinctive. Here is the official description from the American
Iris Society publication, The World of Irises, p.347.
"The rhizome enlarges to many times its normal size, foliage is variously
dwarfed and often folded or pleated, and flowering stems are short, clubby and
malformed. Underground, the roots may persist only near the newer growth.
Sometimes an entire clump will be affected, but usually only a portion is
involved. The unaffected portion may grow and produce normal foliage and
flowers the following year."
Further, WOI--new members please observe the abbreviation for we use it often
here--says that the only reports of this condition have been on bearded
irises, that the "disorder" may appear at any time of the year, and that while
this has been reported from many areas of the USA, complaints "are much more
prevalent in the warmer southern zone"
No pathogen had been identified as of the writing of the book, no "causal
agent" discovered, and thus no control developed.
Not all rippling leaves are pineappling, so do not despair immediately if you
see them, especially in that period of most vigorous growth in the spring.
Often the plant has simply caught its foliage or grown a little irregularly.
Presumptively, if the rhizome is not enlarged you do not have pineappling and
your plant should be fine.
