Hopefully your original image came from a camera and not a post card, but either way, in its presented form, it appears to have a lot of "noise" in it. A good de-noise program can help. PS de-noise is okay, but a more advanced program like Topaz is better to get rid of the noise and striations. Once you accomplish this, highlight or warm the flowers (your subject matter), for a better presentation.
Good Luck.
