These glowing plants are bioluminescent petunias, bioengineered by scientists at Light Bio. You can now not only buy the Firefly Petunias on the Light Bio website, but they are also available to purchase in store at more than 200 US retailers. This comes after online sales proved the popularity of these remarkable plants since their release last year.
They’re fairly new and it’s early in the season so maybe you’ll be surprised one night. Depending on how much artificial light there is nearby like street lights they might be hard to notice and the could seem a little faint as they show up more in darkness. It would be a cool sight to see them light up a neighborhood once someone plants a bunch though.
