About plant names...

This cultivated Xanthosoma is selected for its chartreuse leaves. Different sources list it as a cultivar of Xanthosoma mafaffa, Xanthosoma sagittifolium, or Xanthosoma aurea. I’ve also seen it called “XanthosomaKey Lime Zinger.’” Whatever it is, and wherever it comes from, it is not found in the wild. The name “elephant’s ear” isn’t unique to this species, either. According to Bodhisagan’s Plants and Rants, ”Xanthosoma, along with Colocasia, Alocasia, and other genera with large leaves in the Arum (Araceae) family, are commonly called Elephant’s Ear.”

Identification: Plants are 24-48" (60-121 cm) high. Leaves are large, yellow-green “elephant ears” which seem to fluoresce in cloudy weather. They are up to 24" (60 cm) long and heart-shaped.
