I sort of like what I 'grew up with", that strappy, hound dog eared, sort of thing, but , I'm pretty *adaptable* when it comes to iris ! It's pretty obvious, when looking at all the pictures that different folks post, that *most" seem to favor the view from "just slightly " higher than the bloom, and "just off center" of the fall
like this
but some like a more "straight ahead" view of the fall
and some prefer this angle
But, generally the "fully flared falls ", on a "Big" iris, don't show their full potential unless you look more "down the throat"
as Lucy pointed out the "little guys, being so low to the ground ,are best viewed "down the throat", and the flared falls are more of an "advantage"
and, of course, those that "prefer" the falls to actually "fall" usually wait for the bloom to "relax" before taking a pic, and the "fully flrared" lovers snap as soon as the bud opens, and the flower is still "stiff'. So , I guess what I'm getting at, is depending on what "agenda' the photographer has the picture *may* not be representative of how *most* of the blooms look, *most * of the time!
So ,seeing a picture, or two, of a bloom may not tell the whole story of it's form....and the 'written descriptions" often follow suit, stressing points that are "popular" at the time, and glossing over those that may seen "old hat", or otherwise thought not desirable. So I guess the thing to do is ask lots of questions of those that grow it..Does it *usually* look like that? ...
