Re: Doubled Iris flowers


 

Yeah, I definitely agree. I don't know how to distinguish a developmental abnormality versus a genetic one except for waiting & watching year after year. I have one pseudata called 'Tsukiyono' that is predisposed to having distorted flowers early in the season if the weather bounces wildly between cold & hot. By the end of its bloom season it is consistently hot & all the flowers are normal. It is extremely cold here now, and Tsukiyono hasn't started to bloom yet... so I'm expecting the first flowers to be oddballs.

Recently a double Iris was shown to the list.Â

I have seen double flowers of several Iris species; my eyes always lit up, but double flowers did not recur in following years, nor did the seeds of a double parent produce doubles. From this I speculate that doubling in Iris can be a developmental phenomenon, like fasciation in lilies.Â

Photos of a few Iris doubles follow.Â

First: Two Iris douglasiana flowers noticed this week in a large patch of douglasiana in our garden.
