Lynn,
Mine didn't die! That thing in the photo is still going strong. This has been an easy plant for me. It can take the heat, for sure. I hardly ever deliberately water it. It had aphids last week which I've not seen on it before. I submerged it in the stock trough and swished it around. Most seem to be gone, but not all. I was hoping for a rain so I could locate a fire ant mound. I was going to set the pot on the mound and stir the mean things up hoping they'd find the aphids and take care of them for me. But it didn't rain, so that experiment is on hold for the time being.
Her description made it sound like it just melted away, but I'm not sure it was totally in full sun. I think she had it on her apt. patio, so it probably wasn't in sun all day but I was never there so I don't know how much or what kind of sun. Mine actually gets a lot of sun, but usually very low humidity.
