Temps here yesterday were 108 at airport, but 113 on my back porch (in the shade) & 75% humidity.
Hurricane gets full sun until 2pm - 3pm, then shade. Having to water other potted palnts daily & plumeria every three days.
My Mardi Gras, and a MG seedling are the only ones showing signs of heat stress. Others do have sun burned leaves though.
