The Flower That Glows in the Dark: How a $29.99 Petunia Is Rewriting the Future of Light—and the Rules of Genetic Engineering
On a quiet suburban street in central Nebraska, Sarah Kleiner walks out of her front door at 10 p.m. and looks at her garden. There, among the petunias, something impossible is happening. The flowers are glowing. Not metaphorically, not in the way that poets describe flowers under moonlight, but literally, physically, emitting a soft green-white light from their petals and stems, visible to the naked eye, requiring no electricity, no UV lamp, no special conditions. Just a plant, doing what no plant on Earth has ever done in four billion years of evolution.
