When I mentioned people growing Zantedeschias outdoors here in East TN, I meant the colored hybrids (sorry about any confusion). I'm sure there are people growing Aethiopicas here, but I haven't met any. For me, the summer blooming of Aethiopica types relies on night temperatures, amount of rain, and amount of light. Zantedeschia aethiopica 'Giant White', which has spotted leaves, is blooming now, as well as Zantedeschia aethiopica 'Mr. Martin'. http://www.lakesidecallas.com/images/MMartin.jpg The flower is rising 32" (81cm) above the soil line, and is 6" (15cm) in diameter. I haven't measured the leaves but they are quite large. To show it off, I took it to our local farmer's market yesterday. I didn't get very many comments, but one person did say, 'I didn't know Elephant Ears got flowers like that'!
