I sort of guessed that, but it didn’t quite hang together. Also, you didn’t include the bit about being proud to grow it and it never flowers. Thank you.The tropics in Australia is often called The Top End, it's a common phrase I'm used to using and I often forget it might confuse others. That region has a highly transient population, many people only staying for a few years. And when they move up there for the first time most people will try to grow a few things that they're familiar with regardless of local advice.
The cauliflower is always funny because they spend the first couple of months saying "See. It does grow here.".
People came to south Florida in the 1920s and 30s to farm and there were vast failures. In addition to the heat and bugs, there are no organic nutrients in the soil. None. I’ve had my soil tested and there is nothing there. Even after piling compost on year after year.
