It has been sitting in a one gallon pot in a lot of shade ever since I got it (about two years ago). I am finally going to plant it out (in yet another shady spot, probably, as that is about all that I have) later this summer. (I am still deciding on the spot; there is one spot that gets some sun (more than it has now) that I am considering.)
The flowers seem to start opening in the afternoon, so the picture that I just added to the database was a "new" bloom, taken around 4:30 pm. Generally the blooms are ready to be deadheaded (i.e. are starting to melt) by around noon the next day.
Other than that, I can't comment on the performance (because of the small pot and the shade). Sorry.
