However, although many of the stalks had fully developed buds which were
showing color and were identical in appearance with those stalks not
manifesting
the anomaly, they had collapsed in the midsection, like overcooked green
beans. The base of the stalk appeared fine, and the top of the stalk with
the
ramification appeared fine, but in the middle about six inches of stalk had
simply shriveled up and gone totally limp and collapsed upon itself so that
the
top of the stalk with buds was hanging down. These stalks were found on the
interior of the clump of rhizomes, and there were quite a few of them.
I have seen this in my garden also. More often in clumps that need divided.
It seems to correct itself as the season progresses, which suggests to me
either bacteria or cold damage. This year I had it in a clump of Victoria
Falls and Jurassic Park. Both of these can rebloom so I wonder if the
bloomstalk could be damaged while it is still in the fan? I have seen it in previous
years in clumps that had some slug damage, but this year I didn't have any
slug damage at all. The problem with the frost damage theory is that some of
my early TB's had obvious frost damage including dried buds yet didn't have
this anomaly.

been an ideal season.
