This plant is toxic to cats FYI whatever its ID. It is a lily of some sort. Lilies are all toxic to cats and dogs. You would think cats know better but some cats are actually attracted to these plants. Dogs as well.
It's ginger of the genus Zingiber, probably Z. officinale, of the Zingiberaceae family. It's too tall/vertical to be a Hosta and much too large to be Lily of the Valley. It has tall vertical leaves that have those distinctive ridges. Shell ginger, Alpinia, has leaves that are smoother and the plant is not quite as vertical as Zingiber.
