Roses seem to vary a lot in terms of their capacity to bloom, not just based on the zone but even based on someone's yard and green thumb.
I wonder if there are any famously profuse bloomers out there, which people across many areas have reported on.
Some roses are more consistent than others in terms of bloom performance.
I would love to have a list of roses that bloom a lot - for many people. A list based on fame/wide reputation/ "what has worked for many", as opposed to one based on "what works for me / how X has done in MY yard. "
