In part. Due to the way things are set up in digital cameras, the red 
channel is extra sensitive and gets blown out the easiest. However, 
it's also the easiest to dial back in post processing. When you dial 
down the red saturation, you're essentially reducing the exposure in 
the red channel.

The problem is that if you reduce the exposure overall too much, you 
have to bring the other colours up in post processing, which can 
easily introduce noise and artifacts. The best thing with such pure 
red colours as flowers have is to reduce the exposure overall to 
maybe -2/3 or what you would have normally, and then use the tight 
desaturation tools to reduce just that shade of red until you can see 
the details.
