Your Pup’s Summer Just Got Brighter with This Glow-in-the-Dark Ball from Petco originally appeared on PetHelpful.

Firefly petunias, genetically modified with bioluminescent mushroom DNA, glow in the dark. The glow, primarily from the flowers, is most vibrant in new blooms and is similar to moonlight.

The firefly petunias were invented by Light Bio. A group of bioengineers spliced the petunia’s DNA with bioluminescent mushrooms, creating the glow-in-the-dark plant.
