Re: Iris Douglasiana seed germination


I'm in New Zealand and have some seeds for various irises (Pacific coast
hybrids, Louisiana Hybrids, and chrysographes).  What I've read seems to
say plant in Autumn.  Do I need to wait, or can I start them now on the
South side of the house.  And are they all the same?  The Louisiana seed
is huge.
