Thanks for your comments, and that is why I am looking for the plant. I would like to have the "fruit" to use for salsas and cooking, not to eat as I would a tuna. I recently had some meals that used it as an ingredient and they were delicious. My local Hispanic markets do not seem to carry it or even know what it is (at least the person working in the produce section had never heard of it).
Null - thanks for the tip on Mesa Gardens. I have purchased plants from them before, and I'll shoot them an email
Cheers
Richard
