It was the flower that caught my eye. A strange looking one that looks as though it would be more at home underwater. Then there were the strange green bumps - individual flowers? seed pods? Who knows, but definitely interesting!
This aloe was also interesting, not so much for its leaves, which are different from your typical aloe - say aloe vera perhaps, but for its flowers.
These are the flowers. I noticed there were ants all over the stalks on this. I'm not sure if they show when you click on the photo, but there are several ants here.
