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 the produce a growth since there is no bud eye. Certain varieties and breeding lines are proune to produce "bald" children. For example, us in coastal Calif., always wondered about all the fuss about Dusky Challenger. It and that dark line often produces bald and bloom out children. Bald rhizome, bloom outs, and pineappling is very climate induced. A rhizome grown in a colder climate will do fine the first year blooming and increasing. Plant the increase and the following year these increases will be bloom outs. The plus side is that the one bloom stalk is often spectacular being tall, ramrod stiff and large blooms, but that is the end of it.
