It could be a very mild case of bortrytis, a fungal disease caused by rain on some roses. It doesn't really affect the health of the rose so I wouldn't worry. The new buds will be white unless they get rained on as well. @bluefox23 @Emma915Jones
@Christos I did suspect this to be Iceburg - glad to think I’m not the only one. It appears to be a common feature, however even if fungal as suggested by @ublaszko (thank you btw) it does not appear fatal or catastrophic so I’m happy to leave alone. Thanks everyone
They do change colour towards pink - red spectrum when there's a drop in temperature or if the temperatures are generally low. So it could be that. But since the spots appeared after the rain it creates perfect conditions for bortrytis. Or it could just be because the rain is cold 😉😁 @Christos
Some may have seen before that I have moved into my grandfathers garden. He loved his garden so I am trying my best to maintain etc. He has the most beautifully scented red rose & for the first time last year I took a cutting that seems to be doing okay (touch wood). Here it is. I have no idea of the variety though, sorry.
@Emma915Jones - my tall growing red roses are Papa Meiland and Mr Lincoln. Both of them are very dark red - this one seems to have pink tones but it may be just too much light in the photo. Red is sometimes hard to capture correctly by camera. There are many red roses on the market so I can't positively ID this one. It looks like it will be a beauty😀
