Last year, I got a chilli plant sapling from a family friend. It planted and grew quite well, yielding around three batches during the summer; the chillies are long, green, and turn a bright red if left long enough on the plant.
The family friend suggested "save some seeds," but it was too late in the season and I didn't save any.
Research online suggests that many (most?) of these plants are annual. How can I be sure if mine is annual or perennial?
I left the plant in the soil throughout winter (-20 to -30C). Now that it's thawed out (mostly), I can see the stalks look okay. I pruned the tallest ones down to a few inches, and removed all the hanging dead leaves.
I would like to grow the same thing, so I need to figure out as quickly as possible if I should wait/watch (and is it worth the extra effort?) the current one, or yank it out and replace it with a new one.
