If the buds start to open, but get stuck half-way, with the petals all stuck together, that is a phenomenon called "balling". It is caused by warm, dry days, followed by chilly nights, and some varieties are more susceptible to it than others. Other, more treatable things that can cause similar symptoms are thrips and salt damage.
