Yeees. This is a common problem with flower photos. Blossoms are simply very radiant, highly saturated, without any other colours. So when you take a photo, they seem much brighter than the background, and so saturated that all detail disappears.
So with flowers its a balancing act of trying to make it dark and desaturated enough for textures to appear, but keep it bright enough so that some of the surroundings can be recognized. Different photographers in this genres use different methods to deal with this issue. A high quality polarizing filter can help.
I would add EV (you can look at histogram; the idea is to have colour information spread across the whole histogram, not all bunched on one side), and maybe selectively desaturate parts of the flower so that detail remains.
But good shot, nicely framed, nice detail, good-looking flower.
