My 80+ were only the bought ones. Maybe it is more like 160+ I dunno. I think I waited too long to do La. Iris this year. I will save that list for next year. Those have to be the ones that will work in zone 5.
I got blue and yellow iris seeds from China. I think the yellow might be those invasive ones, but probably not in Maine on dry, in-town land - just can't share them.
