TBManOR said:The potato is a tuber -- the iris (bearded and most beardless) is a rhizome. The two plant structures have some similarities, but quite a few differences in composition and structure, so the two cannot be compared.

Yes, I would definitely agree, a potato is not an iris. I was referring to the 'eyes' on a potato being similar to the 'eye buds' on a rhizome. GuiseppeJ wrote on the thread "Bloom out survey and problem solving" post #1926652 on March 12, 2019 the following:

This is a partial quote......
Bloom out is when every fan blooms and that is it. There is no increase since every increase has bloomed. It is also referred to as a bald rhizome. The Mother (the original rhizome blooms) and there is no increase. Digging the rhizome will show no sign of an increase. Nothing you can do will cause it to produce a growth since there is no bud eye. Certain varieties and breeding lines are prone to produce "bald" children.

From my experience I leave, what I refer to as bloom outs, in the ground for at least another year. When no new growth begins in the spring of the following year it has always been futile for me to cause new growth on that rhizome. Again, I am no expert and learn something new all the time therefore I yield to your knowledge and experience.
