Hi Eva,

I apologize for the late response to your question. The intense heat we have been experiencing could be the reason your blooms aren't as nice as they should be. When it gets hot plants put more energy into survival. The focus moves to root and leaf survival. Another factor that may be effecting your plant is the poor air quality. The Front Range has been experiencing a lot of air pollution from the wild fires happening all over the western US, so this could definitely be part of the problem as well. 

You should just trim off these blooms with stems and see if the plant produces better blooms once the temps cool down a bit. Deadheading also helps the plant produce more and stay healthier.  Here is an article on heat stress that you may find helpful. 

Hope this helps.
