Purple Waffle Plant, aka Hemigraphis alternata, Metal Leaf Plant, or Waffle Plant, gets its name from the puckered appearance of its leaves and striking purple undersides. The crinkly, purple-tinted top of each green leaf takes on a slight sheen and is sure to catch any passing eye. The textured, "waffle-like" appearance of the leaves adds to its visual interest. Being small in stature, the Waffle Plant will be suitable for a hanging basket kept in a nice, bright window.
