Yes it has. Although you'll see beautiful photos
of flowering carpets of Dionea in books, individual
plants can actually flower-away to nothing. However
they may also just go dormant after the exertion, Particularly
as it gets later in the season as we are, and particularly
if you're in an area that's getting colder and having shorter
days. As long as the underground rhizome (?) stays firm
and white your plant is still alive. Take the plants
lead. If it's starting to die back I'd probably cut back
on water a bit and see what it does. If it's just going
dormant, let it. If it dies there's nothing you can do,
but forcing a weakened plant out of dormancy is a good
way to lose it. We have to be patient with nature :-).
