crops that like 100F temperatures

[worth1]

All the beans and peas mentioned are from southeast Asia where it's hot and humid.
Those darned long beans can take over the place in hot humid weather.
That and the edible Asian gourds.

It would not be every day @Whwoz . Tomatoes seem to be okay up to 95F without too much blossom drop, but that is with fans running to try and keep them cool. Last year we had 4 or 5 days in June that went over 95 in spite of fans. Similar happening this year but could be more since it started earlier. There could also be cooler days with greenhouse highs in the 60's, but not too many I think. Then in July and August, highs of 90 would be the norm, with some respite days in the 80's, and a week or several weeks in total so 7-14 days hitting 100 or more, especially if not running fans. Hard to put a number on it, since our summers are so variable depending on wind direction and ice conditions. However when the sun shines, this greenhouse gets hot in a hurry.
I think I might try corn, just because I have the seed.
Sounds like sweet potatoes would take some advance planning and an early start.

Lots of good suggestion above. A couple others that do well for me in the heat are Japanese Purple Mustard (way hardier than regular mustard) and scallions. Scallions are pretty much indestructible in consistent 100+temps and drought. I pick bunch every week and use them just like you would regular onions. I've heard Armenian cucumbers do well in high heat though I've never grown them.

I had so many Armenian cucumbers last summer I was giving them away! We had many heat waves 100F+. They also seemed unaffected by nematodes— the cucumbers I planted next to them did not thrive and had root galls, as did nearby tomato plants.

This year I’m trying Striped Armenian and Dark Armenian.

Next year (if you grow them yet again), I highly recommend Metki Dark Green Serpent melons as your Armenian cucumber. There's a world of difference in taste and usability between them and the standard Armenian Yard Long. They're so good (in my opinion).

@bower
Hey, you might try watermelons, burr gherkins, and stuff like that. Burr gherkins would probably do very well. If you need a bush watermelon, I only know two kinds (and I had looked pretty hard for them a few years ago):

* Sugar Baby Bush (not the same as Sugar Baby)
* Bush Jubilee

Of those, I've grown Sugar Baby Bush, and it is pretty compact. It doesn't taste the same as Sugar Baby, but it's a good watermelon.

Additionally, there are lots of tropical cucurbits you might try.
