Zebra plant's large, pointed leaves are a deep, glossy green with bright silvery almost white veins that create a striped appearance. When the plant flowers, usually in the late summer or autumn, it bears a tall (eight inch) golden flower bract that lasts for up to six weeks. Zebra plants require lots of moisture, warmth, and food to really thrive. But if you're on your game, you will be rewarded with an indoor plant presentation with that "wow" effect.
