Alocasia macrorrhizos Bletilla tuberous aroid has one giant(syn: Alocasia macrorrhiza) This very cool elephant ear is quite different from the typical Colocasia esculenta. The thick, sculpted, glossy green, wavy edged leaves are held upright on dramatically rigid stems. A clump of giant upright elephant ears is guaranteed to stop visitors in their tracks especially if they walk into it! Alocasia macrorrhizos has been quite hardy in the Raleigh area, surviving 0 degrees F, but prefers it a bit warmer.
