I'm gonna hijack this thread a little since the original poster seems done asking. I bought my first EE bulb this summer and it's grown beatifully since being planted in mid-July. But now I'm worried about how to best take care of it for the winter and so it seems I need to be more confident in what type it is. It was labeled as a 7-9 Upright Elephant Ear - Alocasia Macrorrhiza, but it doesn't look like other pics I've seen of this variety, so I want to be sure. Can anyone confirm this based on my picture, or offer up the real cultivar if this isn't the case?

Also, after ID'ing, I'm trying to determine when to slow down on my watering & either bring inside (greenhouse-type environment, but drier), or protect a little outside for the colder temps. What temps are too cold for this guy?
