If this is JFK it has a really addictive fragrance. I say if because a number of roses I bought from a hardware chain this winter have proven to be the wrong varieties. First flower on my still potted plant. I guess time will tell if this really is JFK. Sydney, Australia, 22 Oct 2024. Editing to add that this rose shattered on 31 Oct, so quite lomg-lasting and stayed in good appearance until then.
