I have this rose and some of the flowers open just fine and others open incomplete like the photos attached. I have also noticed that some of the leaves start growing with some wrinkles. Thank you in advance for your help.
Rose Flowers Are Incomplete and Wrinkled
It could be a genetics thing with those particular canes. If you prune them off and those same canes produce the same type of blooms, I would prune the problem canes completely out and other new canes should emerge that will hopefully produce the better buds and blooms. It can also be a insect problem, such as thrips. They make small holes into the buds and mess up the bloom inside before it has a chance to bloom nicely. A systemic insecticide will get after the thrips.
