I checked out 0puntia. My plant and fruit looks nothing like any photos I saw. I can post photos but not real sure how to do that! Can anyone help me on that?

I post photos using an image hosting service like Photobucket or Picasa. If you use Photobucket I can walk you thru it.

I'm gonna try to post a link to a picture of a yellow pitaya fruit - or what we lovingly refer to as Dragon Fruit.

I'm new to the fourm so if the link doesn't work, go to www.wikipedia.org and type in pitaya. That's where I got the pic :)
