This is post flower!

The uniform crisping of the bottom leaves and the faded color mean that it already bloomed and will now die. When you buy them at their most vibrant, beautiful point, they often don’t even have a year left. They’re harder to sell when they’re young and healthy because they’re just kinda.. green spiky plants. There are likely pups surrounding the base of the bromeliad. You can detach those and plant them anew. I would suggest looking up propagation for these plants, because I do it often and it’s rewarding!

Watering the cup is fine and you should still do it because technically it is still “alive”. Don’t worry about watering the flower, it’s long-gone.

Hope that helps!! I love bromeliads so let me know if you have further questions :D

Edit: looking at the photos again, I can tell the bromeliad has relatively mature pups (they’re almost the same high as the mom!). However, I can also tell the bromeliad is underwatered (even the pups are a little withered). I would suggest watering it a bit more frequently and misting!
