I agree that the rose world could use more hand-painted roses. There's a real sense of fun to them. I remember seeing Eyepaint at the propagation gardens at VG once, long ago. In a glorious garden full of the best HT's of the last century and the best old roses from all previous centuries, it was hard not to just stare at Eyepaint. Sometimes it was in admiration for the perfect shape of the plant. Sometimes it was in admiration for the fullness and shrubbiness of the plant. And sometimes it was in admiration of the vibrant red splashed with white that pretty much covered the shrub.
Zuzu, It appears to me from glancing in a 2005 Handbook for Selecting Roses that Stretch Johnson is the listed name for the rose in question. Similarly, the rose is listed as Stretch Johnson in Botanica's Roses. I don't have Modern Roses (latest version) which I guess is the naming authority, but I'm betting that the official registered name for the rose in question is Stretch Johnson. Rock and Roll, Rock 'n' Roll, Rock & Roll are not listed in 2005 HfSR.
It seems to me that one could certainly claim that Rock 'n' Roll and Rock & Roll are two different names because they are spelled differently, but it's bound to be the source of endless confusion. It is to avoid confusion that we name roses in the first place. So while no database would keep you from having the two names for unique roses, I think it flies in the face of reason. Is Fame! a different rose from Fame? When you go to the nursery, and ask for Fame, which rose should you get? I would also argue that a rose really ought to be allowed only one official name (though sometimes with inclusion of obvious alternate spellings). The fact that Stretch Johnson was marketed under an unofficial name ought not, I think, preclude the registration of another rose by that unregistered name.
Rosemary Verey tells a story of ordering a few hundred roses for a bed of one of her aristocratic customers. She orders Camieux over the phone. The rose supplier's agent rights down Cameo. Verey is expecting tasteful white and pink striped roses but she gets "garish orange" ones. Such are the problems associated with names that sound the same.
I've always preferred the original name of Anisley Dickson to the curious registered name Dicky. So I understand the impulse to use alternative names. I do it myself. I might even be inclined to use the name Tango to avoid the obscure double entendre of Stretch Johnson. But I think Rock and Roll in all its spelling forms belongs to another rose. And for some of the same reasons. FWIW.
