This is popularly known as snake plants. I like this as indoor plants because it requires very little maintenance and they are beautiful. I bought a pot of this last year and divided it into two. Now they are growing additional new plants which I could transplant again in some pots.
This plant is comically referred to as the Mother-In-Law's tongue, don't ask me why but I just learned it from a colleague hehehe.
How about you, what is your favorite indoor plants?
