Geneva, unfortunately, information on bloom habits of all cultivars known to rebloom isn't available. The cumulative checklist simply lists all cultivars reported to have managed to rebloom and which zones and states/countries/provinces reported it.
Chuck has postulated several types of rebloom genes based on his own data and observations of others, but only for those genes that affect bloom triggers.
There are other genes involved related to growth rate, root shoot ratio, allocation of energy to roots, shoots and bloom production as well as to disease resistance (mechanisms of repair and resistance), freeze tolerance and probably a bunch of other things that have to be part of the rebloom "package" that each iris breeder automatically selects for because they are what help make it possible for any plant to rebloom in their growing conditions.

  Would that sort of information be listed in the book that they
offer for sale?
