Check out the Rattlesnake Plant! He has narrow, wavy-edged leaves that are pale green with purple-red on the undersides. That looks pretty snake-like to us.
This plant looks great showing off in an indoor pot where his striking foliage perks up a boring corner or office desk, watch how his leaves move and close up at night.
