I did not have any reblooming on any hostas that i have in Wisc [not sure about in IL since i wasn't home most the season]
but I had LACK of blooming. Many of my hostas in Wisc did not even bloom this year.
I know for a fact Guacamole did not bloom, as i was looking forward to it this year.
Many of the newer plants i have, that i got last August, those did not bloom either.
I'm wondering if weather has anything to do with it. We had extremely WET June and July - then a very DRY August and September and going into Oct... I can not even recall the last time it rained anything measurable here. [i think in June and July combined we had about 30 inches! ]
I guess there is always next year.
