Most heat-tolerant plants

procrasticusOctober 6, 2010

Hi there,

I'm looking for plants with the highest heat tolerance you can think of, and I'm talking seriously hot. Like middle-of-death-valley-in-summer hot. I've recently learned that one barrel cactus type can survive in up to 156 degree fahrenheit (69C) heat, so you get the idea of what I'm talking about. Very hot growing conditions. Can anybody help me?

Thanks for looking, anyway.

The cactus in question is Ferocactus wislizeni, "the fishhook barrel cactus, also called Arizona barrel cactus, candy barrel cactus, and Southwestern barrel cactus." Apparently, a rather common cactus. I found a study from the early eighties that found its incredible heat tolerance.

And thanks for mentioning the day lily. I might have to look into it.

Here is a link that might be useful: Ferocactus wislizeni

There is a pine tree known as the "jack pine " from California I think , that has pine cones that will not open until it is 135 degrees Farenhieght . These seeds are the sole food of a bird callled the Jackpine warbler .

Cycads like Dioon edule are very heat and sun-tolerant. They grow well in the deserts of Mexico.

That's a common thing is fire-prone ecosystems, actually. Doesn't mean it routinely gets 135 degrees in its habitat. Just means the cones won't open until right after a forest fire, which enriches the soil with nutrients and thins out the competition for new pine seedlings.
