Avocado

Thats interesting we use to grow these over a bottle of water for the children when they were young we didn't ever have any fruit though ....

Ive another that lasted indoors since last summer I will add pic. I don't think it will give fruit but still makes a good plant.

I grew a lovely Ginger plant from a portion of ginger left over in the kitchen Mf it liked a lot of water I eventually stood it in the fish pond where it grew huge over the summer But then I forgot to take it out for the winter , Groan :o(
