What plant/flower is this?

Question

This plant has been growing in my friend's garden. What plant/flower is it?

Answer 1

That’s an Arisaema tortuosum, a whipcord cobra lily, fittingly named for the very elongated spadix.

While in many cobra lilies the spathe, the tube-petal-like part around the spadix, takes the show, here the unusually long spadix -which carries the actual flowers - is eye-catching.
