I've been curious about how many of the fruits and vegetables we grow as annuals are actually perennials in their natural habitats. I've done a bit of research, but I keep coming across conflicting info. Some sites say certain plants are perennials where they originated, while others insist they're purely annual with a one-season lifespan, even under ideal conditions. So far, the only ones I feel confident about are nightshades like tomatoes, peppers, potatoes, and aubergines.
I've also looked into runner beans, which some sources claim are perennials and produce edible tubers, while others categorize them as annuals, even in their native regions. What about cucumbers and courgettes? Are they strictly annuals even if there was no winter? And I'm curious to know if there are any other interesting crops that might be hidden perennials.

Chilli plants are actually perennial in their native habitats, but they really struggle with frost, which is why we treat them as annuals here in the UK. If you have a warm indoor space, like a greenhouse or even a shed, they're pretty easy to keep alive over winter! I've brought mine inside as a houseplant during colder months, and it's thriving!
Definitely! Just a bit of protection from frost goes a long way with chillies.
Basil can actually be a perennial in the right climate! I’ve seen some people grow basil plants that look like mini trees. And when it comes to tomatoes, they can last quite a while too if the conditions are right.
You might want to check out cucamelons! I just found out they can form underground tubers, and they can survive winter if you give them some frost protection. I've really wanted to try overwintering them so I can get an early harvest!
Yeah, I moved mine inside too, and it's been flowering like crazy after just a month outside!
