I am occasionally surprised at where things grow. For example, this seems like an unlikely place to me. Good thing I'm not the one who decides these things. All of the tiny shoots in this clump don't really care if it is likely or unlikely that they would be able to grow here. They just grow and don't pay attention to all that noise. Maybe I'd do well to just grow and worry about how it was all possible or if it was ever possible later...or not.
