Generally speaking, it requires a bit of energy to flower and for VFT's, especially ones that haven't had a dormancy and/or adequate lighting, it has the strong potential to do it in. However, from what I have observed, the worst I've had are a haggard looking plant (capensis, primuliflora). In some cases, the stalk comes up and the flower aborts (U. tricolor, P. cyclosecta). Only in the case of G. violacae have I seen both plant and flower mysteriously croak.
Bottom line... I wouldn't worry about it.
