Why doesn't my Pink Supreme flower carpet rose go dormant and then bloom for a very short period of time?

1-1/2 months ago I purchased 3 flower carpet roses and planted them in my front yard. Red, Pink %26amp; Pink Supreme. I have noticed that the Pink Supreme is the only one out of the three that goes dormant and will bloom for a very,very short period of time and then not bloom at all for 1-2 weeks. The red and pink has continuous blooming. Why is this?





I looked at the Pink Supreme rose and I noticed that all of the old buds are dead and new ones are just barely coming out. On the Pink and Red I see the same thing about dead buds, but the blooming is continuous unlike the Pink Supreme





I can send pictures as well if you would like to see what I mean.Why doesn't my Pink Supreme flower carpet rose go dormant and then bloom for a very short period of time?
Your plants are young, just planted. Give them till next year. They should all be flowering the same.
