Hi Rmt1 do you just have the one plant - I don't think they are self fertile. Additionally they don't fruit for the first two years. They need good humus rich free draining soil and like a mulch or leaf mould or compost. They are one of the very few Solanaceae you can safely eat the fruit of!

Hi just to let you know that thier is now flowers and we are blessed with bees that visit them they are three years old now.
Thank you for you're time Rmt1
