I have two forms of Arum creticum here.One is the classic FCC form that most people grow, the other was collected by Richard Nutt and is very stoloniferous and does set seed.He said it never flowered for him but when planted here it does flower quite readily.It has a very swept back spathe though quite different from the other one.It is a bit invasive but a nice plant even so, easy in a sunny dry place here.I wonder if it is a subspecies?
