I once got one going by accident. I had the top of a fresh one that I put down by my compost bin. I meant to chop it up and add it to the compost but it was way out back and I forgot. It was on a mulchy spot with rich soil and leaves...and it rooted to the ground and then started to grow! It was just a top from a fruit we had eaten...chopped off about an inch or two below the leaves.
I eventully dug it up, potted it, and took it inside for the winter. It turned into a big spikey monster! After 2 or 3 years it still hadn't shown signs of fruit..so I kind of lost interest...then left it out too long last winter and killed it
So the poor thing ended up in the compost after all
