See text Petunia is a genus of 20 species of flowering plants of South American origin.

They need at least five hours of sunlight every day and flourish in moist soil and conditions of low atmospheric humidity.

[23] A wide range of flower colours, sizes, and plant architectures are available in both Petunia × atkinsiana and other species.

[24] Called 'Firefly', this white-flowered petunia glows due to inserted genes from a bioluminescent mushroom.

[25] The Maya and Inca believed that the scent of petunias had the power to ward off underworld monsters and spirits.
