Tiny Tuesday - Leaf

This leaf is on a house plant, whose name I have totally forgotten, has most unusual leaves.  I have photographed a small section for Tiny Tuesday to show that  the upper side of the leaf is pale green with bright green stripes.  The underside is deep purple.  At certain times of the day, depending on the light conditions the leaves turn and show the Purple side.
So in the evening you can  be watching the television with a Purple plant on the hearth and wake up the next day to a bright green one.

Thank you Mary Eliza R for hosting the tiny challenge this month.
