Thecommon method of propagation is by means of cormels or offsets.These are removed from the parent corm and planted in the open,where some of them will flower the same season, although most ofthem will require a season’s independent growth before they bloom.If cormels are desired in abundance, the large corms should notbe allowed to flower. Some varieties do not produce cormelsreadily, and these may be made to bear them by cutting or ringing.Aside from cormels, one or two new corms are formed above theold one each year.
