Jim W., help me understand what you mean when you say "Few of the iris were registered with the American Iris Society, but 'Eco Easter' is one of those." Are you saying that 'Eco Easter' "is one of those few which are registered? The link you provided indicates (if I'm reading it correctly) that 'Eco Easter' is not registered. I'm confused. And can anyone confirm that Jacobs introduced a cultivar with the name 'Eco Improved' and another cultivar with the name 'Eco Easter'? Jim McKenney
