Contrary to humans, who usually find intense heat rather annoying to say the least, cacti plants seem to love it!
Here's the evidence:
This little beauty started as an unhappy, baby indoor cactus that a friend gave me three years ago, because she didn't know what to do with it (!), and quite frankly, it didn't seem to be alive. I placed it on my balcony, and gave it a little water and plenty of light. And now, three years later, it has grown more than 5 times its previous size and is in bloom!!!
Once again, nature shows its beauty...
