An annuum with double flowers discovered by Massimo Stomeo.  
 
In my experience this past season they can be somewhat slow to germinate and it is fairly difficult for them to set pods.  This will be a fun one to make crosses with.
 
There is also a Petalosa group on FB run by Massimo if you would care to join: https://www.facebook.com/groups/1133188044573055/
