the leaves look like prayer plant, rather than a ginger. But I could be wrong.

well, duh, that's a prayer plant in the back. sorry!

The inflorescence looks like beehive ginger, but they're usually red-orange-yellowish type colors.

Where did you find it?

Maybe a costus?

And did you know that prayer plant is related to ginger? They produce tiny white and purple flowers.

That is not a Calathea "in back" - in fact that purple bloom is the inflorescence of Calathea zebrina.

wow, gorgeous. guess I'd better fertilize mine.
