Black and yellow spots on leaves

Afternoon @wiseowl I wouldn't know sorry had it for a good 8yrs, first it was in a pot and as it matured got taller but the flowers do come like this, the pic's off the net and I won't know what colour they'll come this year because my hubby places iron filings around the roots so every year the rose changes colour. The first year they was pink, then they came peach and last year they was peach mixed with yellow but this is how the head is and they're quite large

Evening @wiseowl We'll know more when the summer comes and it blooms...pictures will be taken
