It is a hot day on the east coast of the US and there are still people without power. They should get it back at the end of the week.
In the meantime, Cactus would be fine in this heat. They can take extreme temperatures of cold nights and hot days.

Here are the pictures. The four pictures are of Saquaro Cactus which are the ones show in old western movies. The first picture is of the flowers. All of these are from Wikipedia Commons.
