I have had reblooms here for practically the first time, and by the way, Stella has NEVER rebloomed for me!! I just posted some on the September Blooms thread. I also have a couple of late bloomers - the most amazing this year has been After Awhile Crocodile - more pinkish than red - but it is blooming like crazy throughout the month of Seprember.
My Best In Class is a solid dark red - and has a rebloom scape, but I am not sure it will bloom again prior to frost.
Martin Blondeel is also a red, and has been reblooming for me.
Double Cherries Duet also rebloomed for me, but I missed it because the leaves of the larger ones around it obscured it - then the bunnies have eaten the next several buds.
