I've had only some selfs rebloom and Lest We Forget. I purchased a ton of colorful ones this year, but haven't disciplined myself enough to keep them watered, especially this past summer. Nothing yet to emerge, but they're all new though.
I have noticed random ones not registered as rebloomers pop up too on various FB post and other buds. Sometimes a hybridizer may work for the feature, but it simply doesn't happen in their garden. As it may after being shipped off and introduced to new soils and different climates. I hear House Arrest by Keppel and some others are doing it.
If it's in the genes somewhere in the mommy and poppy plant it's quite possible to eventually occur. I move mine yearly, so I never give them the opportunity to settle. My Pink Reprise is my only potted rebloomer though that I've kept together. 5 gallon pot that started with 2 rhizomes and now has 12 after 1 year. I've kept it out of dormancy, but still no fall or winter bloom after 2 years.
