@Carter - I think you got it, by George. Good work. I'm kinda surprised you could kill yours. I'm an expert at killing (or at least abusing) plants but don't think I ever killed a Bromeliad. When I lived in Austin I had way too many of them. I've also had my share of 'bros'.
@LindaHarr - I just knew for sure that someone would come along and give us the exact name, she said skeptically. Speaking of being skeptical, plant labels are handy, especially with a gift, but they are not always reliable. But yes, do tell her to water it sparingly. However, I think it might like to be misted so maybe you can help her with that. And be on the lookout for 'pups'. They are the offshoots that grow from the base of the mother
ship plant and can be snipped off and potted and become all grown up. For your mother's sake, probably leaving the pups attached will keep the plant looking fuller. Ok. That's a guess. I've not grown this particular Bromeliad. But I think it was a lovely gift for her 93rd birthday.
(Don't tell anyone but my mom had dementia also.)
And because it bears repeating, Welcome!
