   Patricia, I have heard that crowding the seeds in a pot sparks germination.  I
cannot find a print reference.  It is not in TWOI, or I didn't find 
it.  On the practical side, not all of your seed are going to 
germinate in the first place and some that do will be wimps or even 
albinos and die so why give them a great amount of space.  You really 
need to sprout them in pots or in a seed bed with dividers so that 
the seeds don't wash away or into each other over winter.

TWOI (THE WORLD OF IRISES) says first year germination of tall 
bearded iris seed can vary in percentage from 90 per cent down to 
five per cent, and germination can extend over a period of 15 years 
or more.  Seed can remain dormant but viable for 18 years in a 
seedbed.  So, I use the pot method and rarely hold over a pot for the 
next year for additional seeds to germinate.  After the seedlings are 
removed from the pot, destroy the remaining soil.
