One of the weirdest plants I know of, Welwitschia Mirabilis can live for thousands of years. It grows only two veeery long leaves in its’ entire life. They eventually develop splits in them, and appear as if they have  multiple leaves. It’s often called Octopus of the Desert due to its unusual appearance. Native to Namib desert.
