Some roses look pretty much the same throughout the life of the flower, while others evolve in a manner that makes them look like very different at each stage of their cycle.
This is the climbing rose named 'Royal Sunset'. It is a lovely climber with big blooms throughout the year.
As you can see by the pictures of the flowers all on the plant at the same time, they change dramatically as the bloom matures, ranging from a deep orange to a soft pink, all within a week.
This makes for a lovely show with so much variation from one plant going on at the same time. I think this is a lovely and interesting rose.
