Only the top corm will flower the following year Lee-Roy, but if you separate them, eventually they all will send up a flowering stem.There are two chains there, both leading/joined to the original corm.I have never watered these and they are exposed to howling sea gales.If I took better care of them, the flower bracts would be more impressive, but I don't believe the corm quality would be improved.My summers are pretty hot --several days over 40c and I am always frost free.
