Re: Iris hexagona

 

Hi All,

Interesting subject! 

As for sources, Plants Delight Nursery offerers an I. hexagona. I emailed asking about provenance and got no reply. Also it's thought that the cultivar 'Cathederal Blue' collected by Caroline Dorman is I. hexagona. CB is available from Bois d'Arc. I had a hexagona clone, purchased from Farron Campbell and now lost, that was very similar to and bloomed late with 'Cathederal Blue'. I don't know the provenance for Farron's Iris either.

Seanâs post raises interesting questions.  I. hexagona was named based on a South Carolina specimen, but the iris apparently is all but extinct in South Carolina.  For a number of years I have been trying to locate a start in order to compare it to some Florida irises and those in Louisiana (where I live).  While some people do recognize I. savannarum, others do not, and, in fact, some apply I. hexagona to I. giganticaerulea in Louisiana. 
 
My question has long been where do âtheyâ write this stuff down?  How could I find documentation that one species name is appropriate and another not? 
 
I am very doubtful that there is only one species in the Series Hexagona in Florida based on variation Iâve seen in growth  habit and bloom season.  But species are invented categories, and I donât pretend to know how to apply them or where to draw lines.  However, there is clearly significant variation within I. hexagona-I.savannarum-I. giganticaerulea that âtheyâ need to recognize and document.
 
I have some information on the Florida irises on my website that may be of interest:   http://zydecoirises.com/Species/Florida/FloridaIrises.htm

By "real", do they mean Iris hexagona sensu stricto? Some taxonomists consider most of the plants usually called hexagona to be a seperate species, Iris savannarum. The name I. hexagona is then restricted to a rare species found only in South Carolina and Florida. Most, however, consider them to be the same species. The flowering period is reportedly dramatically different where the two overlap. The Rainbow River plants would be the earlier-blooming I. savannarum. I would guess nobody sells the "true" hexagona, since savannarum is far more common and widespread and usually goes by hexagona.
