I picked up my plant at Logee's, where they have a mature specimen that is really incredible. It was just a little bump when I got it, alomst 2 years ago. I place it in a East facing window in the winter, so it gets morning sunlight. In the warmer months, it goes outdoors in a mostly shaded spot. I have found that the leaves burn very easily in the sun. The "shell" has grown some, & is now showing some ridges. It has been fun watching it change. I tried to root a vine that I had cut, but it refused to root in water. I have the vines climbing up over a rounded wire support.
Here is a photo of the "shell" - it is only a little under 2 inches across.
