Mike - These are the ones I acquired this year that are M-L or L bloomers. All new, so none have bloomed this year for me, but I am sure they will next year:
Judge Roy Bean
Sings the Blues
Lavender Stardust - This one actually did bloom the latest of all of mine, but not into Fall.
Calgary Stampede
Chinese Scholar
I have several also that are Mid-season bloomers with rebloom and/or extended bloom .... so those may also continue to bloom late in the season, too.
