Coffee Frenzy is listed as double but I only had one double bloom last season.
Always double; Condilla, Greywoods Dottie Dolittle, Micro Wave, Peach Magnolia, Pink Pompon, Sweet as Can Be, Unlock the Stars
Siloam Double Classic throws a few singles early on, then nothing but perfect doubles
Occasionally double; Double Tulip, maybe 50% of the time or less.
An unexpected double was Blue Racer, which threw a double flower last summer, although listed as a single bloom
I have many doubles planted last year that I haven't seen in action yet.
