An interesting situation for Sansevieria. I'm keeping an eye on a place for a friend who is away for a long period. There's some Sansevieria growing near an outlet from an airconditioner. There's pretty well a constant stream of water which is pooling around the plant so it's sitting in shallow water. And there's no signs of the plant not liking it. I'd always thought they needed good drainage, this one obviously doesn't and still looks very healthy.
