Thanks everyone, yep from doing a Google image search thats the plant for sure, i had heard the name but never seen one. Seems the fruit start purple, then turn cream, then yellow, then orange, then finally red & that`s what i was going to ask next.
Which seeds to keep? obviously the very ripe red ones.
The lady at the market who sold Trish the plant didn't even know its name, Trish asked can you eat the fruit & the lady said its "Oh no it just an ornamental you cant eat them" i said rubbish you can eat ornamentals & from reading you can & there quite hot.
Mezo.
