Tropicals & Tender Perennials: I think I have a 'Black Magic' Colocasia esculenta - SICKLY, 1 by HollyErin

My neighboor has a large Caladium/Colocasia that is blackish. She is having great luck with this plant and had tons of 'babies' sprouting up everywhere. She gave me one of the babies and I planted it around my river birch tree with hostas (several varieties) and Setcreasea purpurea (Purple Heart). The plant did great, making a number of fronds, beautiful color. In a matter of 3 days, the leaves have begun to "dry out" around the edges, the babies are dying before they get over 5 inches tall, and the leaves in general look really bad. I am in Memphis, TN - zone 7 - and the temps have been in the upper 90's with suprisingly low humidity. I water frequently and the plant gets dappled light. Does anyone know what is going on?
