With plants as pretty as these, it's with regret that I have to announce none of them are edible. The pitcher plants, however, will eat YOU.
The strange one at the top (not my hand, the plant) is known as either monkey or kangaroo's tail. Earlier today, at a winery, I was told by the proprietor that the kangaroo derives its name from the inquiry "wot's that orange-colored rodent?"and the Aboriginal reply to the English-speaker, "Que? Can't hear you." Say that once fast and you'll figure it out. I don't think it's a true story, do you?
