Other planets may have aliens, but we have this...
It's not pretty to look at, but Namibia's plant Welwitschia Mirabilis can truly claim to be one of a kind. There really is nothing like it.

Welwitschia plant consists of only two leaves and a sturdy stem with roots. That's all! Two leaves continue to grow until they resemble the shaggy mane of some sci-fi alien. The stem thickens, rather than gains in height , and can grow to be almost 2 meters high and 8 meters wide. Their estimated lifespan is 400 to 1500 years.

The sexes are separate, i.e. male plants and female plants.

Welwitschia is thought to be a relic from the Jurassic period when such plants (called "gymnosperms") dominated the world's flora. Its ancestor got trapped in an arid environment, and all its close relatives long since disappeared.
The plant is said to be very tasty either raw or baked in hot ashes, and this is how it got its other name, onyanga, which means onion of the desert.
Also some like to wear its unique shape as a jewelry:
