I just happen to disagree, with either "celebrity status" or "subconscious' factors, playing much role, in voting for a plant, yes a flowering plant, mind you, being compared in such a manner, as to base it's long standing position, on name recognition, familiarity , celebrity status, or politicians, which are all humans, or their attributes, for that matter..
It is a well appreciated Iris & favored by many. Plain & simple & has been, for a rather long period of time. Are there other Iris out there, I'd vote for, instead ?
You can bet, on that. None of my orders, include D.C. ! As I actually, enjoyed 'Titan's Glory' probably more so.., too, back in the day..
But, now I just so happen to like, some of the newer cultivars...
Apart from growing species, from seeds ,that I happen to like also, & apparently have been popular, for thousands of years.. & often used in creating aril-bred hybrids, but I'm not really interested in them for that. Just like I grew many cacti of Mexican origins (greenhouse grown ,also, & I grew from seed, too ) for about 20 years...
