Please how growable and eatable are the seeds of water chestnuts? The floating rosette type rather than chinese water chestnuts (Eleochasris dulcis where you eat the corms) I believe they succeed to water domination in areas of the US?
I am looking around for ideas of small plants to grow in water butts that wont mind a bucket swishing past them periodically. I am going to play with floating lettuces etc in polystyrene too. I'm on a mission to utilise my water butts for multiple functions.
