Tips for Choosing the Perfectly Healthy Rose 1.The head of the rose needs to be firm and hard. Squeeze the bulb of the rose if it is squishy, don't buy it. It may not open! When you squeeze the middle of the rose head, it shouldn't open. 2.The perfect rose is going to be somewhere in between being open and being shut. If the rose is completely shut then it may not ever open and if it’s completely open then it might fade too quickly.
