Did you know some plants glow in the dark? These plants with bioluminescent qualities are fascinating, look magical, and bring a sense of spooky wonder during the Halloween season.
Most plants that glow in the dark are not natural but have been engineered with genes from fungi or other bioluminescent sources to give them this unique quality. While there are definitely some discussions around bioengineering plants, we can’t help but admit how fascinating these plants look at night.
Bioluminescence is a fascinating phenomenon that creates a cool light, giving that glow-in-the-dark look we often see in aquatic creatures, like algae and jellyfish. Fireflies also display this response with natural organic substances and enzymes.
When combined with certain genes from glowing species, plants exhibit some pretty cool glowing traits. Some fungi, which play a key role in making plants glow, have the ability to produce light through chemical reactions.
Did you know that more than 70 types of fungi can actually glow in the dark? It’s pretty fascinating that some of them light up to attract insects, which helps them spread their spores! They light up to help insects spot them more easily at night.
Let’s take a look at the 5 most incredible plants that glow in the dark:
1. Foxfire Fungi
Foxfire fungi, or Armillaria mellea, is a really interesting organism that you can find in both deciduous and coniferous forests all over the world. This incredible fungi glows in the dark, giving off a fascinating light show!
This glow isn’t just for looks; it actually has a function. The foxfire fungi shines its light to draw in insects, which play a role in spreading its spores. This allows the fungi to spread out and colonize new areas.
2. Firefly Petunia
Firefly Petunia is another fascinating plant that glows in the dark. It has been genetically engineered to glow with a gentle, moonlit glow when the sun sets or in dimly lit spaces, thanks to its bioluminescence. The bright buds and fresh growth soak up the sun’s energy, creating a lovely display of light all around.
Firefly petunias are always shining bright, but it’s when the sun sets that we truly see their hidden magic. This glow-in-the-dark plant comes from years of research into bioluminescence. It’s best to check it out at twilight when the petals light up with an incredible greenish-white glow.
This plant loves full sun and needs just a bit of watering, so it’s perfect for anyone looking for something easy to care for. This stunning beauty is bound to be the highlight of any garden, lighting up the night with its magical glow.
3. Phalaenopsis Orchid
This is a relatively new type of phalaenopsis orchid that was developed by a research group at Chiba University in Japan and made its debut at the World Orchid Show in Tokyo back in February 2024.
It’s a white-blooming phalaenopsis that glows green in the dark and under a blacklight and glows all over. This unique phalaenopsis is just as easy to care for as the well-loved moth orchids you might have at home.
4. Tillandsia
Tillandsia species are fine-leaved, silvery-green air plants that soak up water and nutrients right from the air around them. These tropical houseplants are super popular for becoming glowing beauties, not by genetic modification, but by using a special compound on the leaves.
When a synthetic nanoparticle in the compound is exposed to UV light, it triggers a light reaction. Even though the glow doesn’t last long, just an hour or two, you can easily recharge it with a bit of sunlight.
This coating is said to be nontoxic and safe for people, animals, and the plant itself, but it’s important to note that these aren’t exactly natural glowers.
5. Jack-o-Lantern Mushroom
These poisonous mushrooms remind me of something straight out of Alice in Wonderland! During the day, they shine bright orange, and at night, they naturally give off a warm glow, lighting up the landscape like little lanterns.
It’s important to note that while they might be fascinating, they’re toxic if ingested. The orange light serves as a helpful warning from these fungi, as many orange creatures in nature can be poisonous.
The spooky, magical glow feels like something straight out of a witch’s tale. The organic substance luciferin reacts with oxygen to produce warm fluorescence.
The mushroom resembles a lovely chanterelle but features funnel-shaped caps and smooth edges, unlike the frilly gills of the tasty ones. You can spot it on decaying branches, trunks, and debris during late summer and fall, just in time for all the spooky fun!
