I grow several different Iris variagata and they all rebloom for me
here in Guelph, Ontario, Zone 4/5. Last year (and several other years)
they were continuous bloom once they started rebloom. The variety Iris
variegata reginae is violet on white, and although it doesn't rebloom
I have a seedling crosed with diploid MTB that occasionally puts up a
fall stock. I have a number of crosses of variegata with MTB and keep
looking for rebloom, but none so far. Perhaps future generatyions will
have rebloom.
