I have had this plant for 2 seasons and it blooms 4-5 times a year. This latest blooming had produced deformed flowers. It's like the petal/flower is not joined up. Any ideas?

As long as you are not seeing any other signs of disease or insects on the plant, I think this is more likely a fertilizing issue.

A soil test can be preformed easily to take the guess work out of this.
