spotty

when i bought this cultivar, named "jalitah", the label promised it would look like this: http://foto.mein-schoener-garten.de/neu,foto,user,cameo,654616,orig.html
unfortunately, mine blooms just plain yellow. except this latest blossom is sporting magenta spots. i've been wondering whether it might've been a label mixup, though in general the rose does comform to the description. maybe it's something in the soil, or something missing, that would get it to bloom according to type?

I get those spots on our roses sometimes, I don't usually bother treating but then I'm lazy and try to not treat every single little thing.
