Mother-in-law's tongue ( Sansevieria )
 

this is mine. Probably had it for 10 years, already broke one pot and is doing its utmost to do so with this plastic pot. The leaves that are upright are over 6ft tall.
Its a monster............just like my mother-in-law. JUST KIDDING !

I water this roughly every 8 weeks. It blooms every year.......and those upright leaves are unsupported.

Pretty variegated one! Blooms fragrant at night!
