I was given a chilli plant by my friends neighbour but this is what I've ended up with? I'm rather new into gardening so not really sure what I'm looking at. Any help will be greatly appreciateted.
That's no chili plant. Do you put seed out for the birds and could some have dropped into the pot?
A fine example of a weed called Fat Hen which produces abot 20,000 seeds so it's not surprising they get everywhere and probably in the compost of the plant you were given! Here the link on this site:
Don't chuck it tho....eat it!
