Random plant event: Fittonia argyroneura (albivenis?) flower

Weirdly, I'd never seen these flower prior to this job. Or more likely I'd seen it and paid no mind. Whichever. Two winters in a row now, they begin building these elaborate little towers in about October or November, which reach full size in December . . . ish (okay, so I don't know exactly when it happens: sue me), and begin popping out these tiny yellow flowers. It's interesting, but not particularly decorative, and I'm never sure if I should be taking off the flowers or leaving them on.

Probably I should be taking them off. I imagine building these takes a lot of energy from the plant, and the customers aren't going to buy for the flowers. But still. I hate to sexually frustrate the plants. I worry about violent uprisings.
