Here's a Musa sikkimensis Daj Giant that's planted in a nearby gully. It doesn't get sun till noon and it gets really get hot against the rock wall. The leaves lamina (leaf blade) fold downwards to reduce tempature, and also save water that it uses for cooling the leaf. Also a wind torn leaf is supposed to be able to conserve water even better. I've noticed this more on these seedling bananas because the view from above lends a better from above perspective.

Musa balbisiana seems to handle the heat better than others, and fold less. Ensete superbum seems to fold upward instead of down. And various edibles seems to do this to different degrees.

Yes, it's a seed grown one that sprouted two plants, so I just left them together. I also planted Musa basjoo, Musa sikkimensisXparadisica, Musa cheesmanii, Musa helens hybrid, Musa balboa park, 2 Alocasia borneo giants down in the gully, and planning on planting a few others there as well when they get bigger.

I've noticed the leaf folding sequence on my edibles during our hot, dry summers. I put my hand inside the lamina once, and found it to be very wet. (please, no jokes...:ha:)
I imagine it is a great way for the plant to reduce transpiration. When the Delta Breezes come on in the evening, and the temperature drops, the leaf will open up and stay that way til the next afternoon, when it'll close up again.

Sounds like you've been busy.

Yeah, it's been tough work, but it's one of the places that needed some landscaping. So far 10 holes with good dirt, and a few more to go. I'm also doing 17 holes in a row on the far side of the gully with 15 E.superbums, and 2 E.glaucums(all from seed) between coconut palms. It's the access route for the neighbors to the beach, but so far only 6 holes dug and planted.
