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.
These Petunias have been in circulation for over a year. The only difference is that you can buy them in-store as well as online now. They are not an invasive species but very common. I have heard of no problems as of yet and I think any issues would be extremely minor and putting some flowers out there is a net positive considering climate change and electric light pollution. I don’t think we have much to worry about.
