Definitely one of the most unusual members of the snake plant family, the starfish Sansevieria is equal parts alien and aquatic-looking. This prolific cultivar will continue to add length to it's arm-like leaves while shooting up spikes of new pups, filling any available surface area over time. At any size, these weirdos are a conversation-starting addition to any plant collection. 

Like all snake plants, these guys are nearly indestructible and thrive on neglect. They can handle dark corners and bright windows, and want to dry out completely between waterings.
