I think I figured it out, but it's because I Googled the image @viking-ventures posted. If I guess it correctly, I think she should still get the prize...

So my guess is the nightblooming cactus/night-blooming cereus, native to Texas and Arizona...

She already said that my image was incorrect...
I think I saw another good image earlier that it might have been, but I can't find it right now...

(That's not meant to sound as harsh as it came out - I'm all kinds of edgy this morning.)

No worries - I think there's something edgy in the air today. And I used your image as a jumping off point, which is why I figured you should still get the credit. 😊

Its very similar to that image. Im sorry your feeling edgy, im just tired. Very very tired. So much so that I feel like crying... gotta love getting kicked all night by a mini minion. Lol... hope you feel better soon. X

Nope its not a nightblooming cactus or native to the US.

I want to let someone else win but is it located in Argentina?

Nope not from Argentina. 😁

How about Chile?

No not from Chile either. Tomorrow ill give the country if not guessed yet. 😁

I have added the country now @viking-ventures, check the post above and good luck!!!

Still the Atacama desert then. I'll get back to you - will try once more.

Just checked this and Dr wiki told me its primarily in Chile :)

hahaha! That's funny. Of course, the cactus might still have originated in Bolivia before it walked. :-p
