I've had two different tenuifolia. Note the word "had." I think I'll give it a go. My problem isn't being able to water enough (probably do SH) but in the past I was never disciplined enough to bring inside when temps got into high eighties, nineties, 100. They really don't like that. I have a few other genus now that I bring into air conditioning in the summer. A slow learner here on tolerating heat. Plus I set an alarm on my calendar.

PS In summer I had always figured the really high humidity would be better than the high heat. I pushed the envelope too far.
