HaHaHaHaHa! Mark,
Your quote message, "DON'T PANIC" brought a laugh to me and thats a good thing! Laughter heals the body and Soul....
Cissus Quadrangularis definitely doesn't!
Anyway, and back to the point;... Cissus does fruit with small red Holly-like berries yet I have only had mine do so once.
Thank you for asking and I'm looking forward to the next time they do bloom and fruit for me. I'll surely photograph the event!
