Firefly Petunia - Glowing Plant

Firefly Petunias are identical to conventional petunias, except they emit bioluminescence like fireflies. No special treatments or conditions are required.

The luminescence of Firefly Petunias is best experienced in a dark room or on a moonless night.

Our petunias emit a soothing glow that is similar to moonlight. New flower buds are the brightest part of the plant.

The brightness of the plant is determined by natural cycles of its growth. During the day, the plant harvests energy from the sun, which it uses at night to glow. The bioluminescence is best observed after twilight.

The fastest growing parts of the plant will glow most brightly. Light is emitted primarily by the flowers, with the youngest ones glowing brightest. As flowers mature, their luminescence diminishes.

A loss of glow may indicate stress or poor health. Try these steps:

Yes, they are. Firefly Petunias gently glow thanks to a genetic recipe for bioluminescence derived from tropical mushrooms. These mushrooms are found in forests worldwide, and mechanism of their bioluminescence is one of the most well-understood. Bioluminescence of Firefly Petunias was achieved by the careful transfer of five fungal genes, which were configured to convert a small fraction of the plant's energy into light without disrupting its healthy physiology.

Firefly Petunias do not cross-pollinate with native North American plants. It is also unlikely to have any noticeable impact on wildlife. Its soft, moonlight-like glow is far dimmer than the artificial lighting commonly used in homes and gardens. Additionally, the bioluminescent components are not known to be toxic to pollinators, including bees.

These plants have undergone rigorous regulatory review and have been approved by the USDA in 2023. The USDA found no plausible pathway by which the Firefly Petunia poses an increased plant pest risk compared to unmodified petunias. After analyzing its biology, traits, and potential impacts on plant health, pests, non-target organisms, and weediness, the USDA concluded that the Firefly Petunia is unlikely to pose increased risks.

Like all plants, Firefly Petunias thrive with sunlight, water, and soil. Their bioluminescence is encoded in their DNA, requiring no special treatment to glow—just good health and sufficient energy.

Firefly Petunias are shipped exclusively within the USA, as they are not regulated by the USDA as genetically modified plants. Other countries may have importation and usage restrictions

Shipping can be stressful for live plants. Upon arrival:

The Firefly Petunia is shipped as a small plant rooted in a 4” pot. As flowers tend to suffer in shipment, the petunia will arrive with developing buds. It may contain a few newly opened flowers. With good growing conditions, it will quickly attain about 8 to 10 inches in size with abundant white flowers.

Yes! Firefly Petunias thrive indoors if placed in direct sunlight. A south-facing window or full-spectrum grow light works best. During winter months, expect slower growth and fewer flowers due to shorter days.

Water when the top inch of soil feels dry to the touch. The soil should be moist but not soggy. Avoid overwatering, as standing water can harm the roots.

These plants flourish with 6 to 12 hours of direct sunlight daily. While they can tolerate partial shade, reduced sunlight may diminish their bioluminescent effect.

They thrive in 65-75°F (18-24°C) temperatures. Avoid drafts or placing them near heating vents, as extreme temperature changes can stress the plant.

As heavy feeders, Firefly Petunias benefit from balanced, water-soluble fertilizer applications every 1 to 2 weeks during the growing season. Incorporating chelated iron and micronutrients like manganese, zinc, and copper can promote vibrant foliage.

While self-cleaning and not requiring deadheading to continue blooming, occasional pruning can shape the plant and encourage bushier growth, especially if it becomes leggy.

While Firefly Petunias are non-toxic, they are not intended for consumption. Keep them out of reach of young children and pets to avoid accidental ingestion.

Common pests include aphids, whiteflies, and spider mites. Regularly inspect your plants to detect and manage infestations early.

To minimize fungal issues, ensure good air circulation around the plants and avoid overhead watering, as overly wet or humid conditions can promote fungal growth.

Our Firefly Petunias are protected under patent, and as such, propagation and breeding are not permitted. These petunias are sold exclusively for personal use.
