MYTH:
"Firefly™ Petunias are delicate laboratory creations that will melt, wither, or permanently stop glowing if summer temperatures cross 90°F."
FACT:
Firefly™ Petunias absolutely love the sun and thrive in warm weather! The bioluminescent trait is deeply integrated into the plant's DNA and is perfectly stable in the heat.
The Summer Heatwave Exception:
While the internal light loop doesn't mind the warmth, the petunia itself is still a living plant that can experience physical stress during prolonged, brutal temperatures over 90°F.
If you live in a region experiencing extreme summer heatwaves, we recommend growing your petunias in containers or patio pots rather than directly in the ground. This gives you tactical flexibility to easily manage soil moisture and move your pots to an area that provides filtered afternoon shade or morning sun only. Keep your plants well-hydrated, feed them their nutrients, and enjoy a radiant backyard view all summer long!
