or heat-producing plant. The plant prefers to live in colder non moving water and requires warm temperatures in order for the flower to blossom, hence the plant must distribute a lot of energy to keep itself warmer than its natural environment (above 90 degrees Fahrenheit).Lamprecht, I., et al. “A Tropical Water Lily with Strong Thermogenic Behaviour—Thermometric and Thermographic Investigations on Victoria Cruziana.” Thermochimica Acta, vol. 382, no. 1-2, 2002, pp. 199–210., doi:10.1016/s0040-6031(01)00734-1. “Victoria Cruziana Orb.: Plants of the World Online: Kew Science.” Plants of the World Online, powo.science.kew.org/taxon/urn:lsid:ipni.org:names:605778-1.
