The bird's nest sansevieria is a more rosette-shaped snake plant, and forms a cup-like structure, similar to a Bromeliad. This guy, however, does not like water in his 'cup', like the bromeliad. Super hardy and low-light tolerant, and really rarely needs watered in most homes. Our general rule of thumb, is once a month when you pay your bills, water your snakes and zz's! You'll always want to feel it first to make sure its not still wet.
