Re: Iris versicolor vs. virginica (#1 of 2)

I have been hunting off and on for a rather well researched article in SIGNA by Jim Seeden that as I recall gave specifics for differentiating I. versicolor  from I. virginica shrevei. Being in the middle groound for the two, I paid a lot of attention to identifying the many plants of both that I had. Of the top of my head, I'd say this is shrevei--more yellow in the signal, longer standards, etc. but I think there were some clones I couldn't identify for sure till they had seed pods, but which had long and which short? I just don't recall.    Joan Cooper, Minnesota

Last year I reported on Hamilton County Parks District propagating various 
wild flowers of locally native genotype.  One of those was Iris 
versicolor.  When I posted pictures of them last year some people 
questioned if it wasn't Iris virginica instead.  Well, I went back last 
summer to check the seed pods, and as I recall they were smallish, and 
filled with shiny brown seeds.  For me that was sufficient evidence to 
confirm them as Iris versicolor.

However, I got to acquire some of their irises and today they bloomed in my 
garden.  In a million years I wouldn't guess these to be anything BUT 
virginica (or shrevei).  Isn't it true that virginica seeds have a corky 
coat like Louisianas?  How about shrevei seeds?
