Usually within a couple days. The petals and sepals wilt in many Phal species, or it became green in other Phals (e.g. P. amboinensis in Fig. 6 of the link above). The fruit could elongate for a couple months, but it elongates quite rapidly in the beginning. The link I provided above has more detailed timeline of what happens after fertilization.
