That's true... but there's also a saying along the lines of "a burned hand learns quickest". I might get "experience" and learn the finer points about exhibiting irises quickly by entering, but I'm sure there will be a certain amount of pain involved (because, let's face it, there's always going to be some amount of ego involved when you enter a show... and egos bruise).
Certainly I have learned that you can learn a lot from talking to the judges ("why did I get only a white ribbon - ?") or listening to them (if you happen to be clerking as they judge).
I didn't win any purple rosettes until I learned (from talking to the judges) to 1) not exhibit something that typically behaves in contrast to its registration data, because the judges may not be personally familiar with the plant's quirks, and they will take the registration data as Gospel Truth (no matter how grossly inaccurate it is) and ding you; 2) not cut off scape branches even though there is nothing left there but old bloom scars, because otherwise the judges assume you had next to no blooms on the scape and will ding you; and 3) not exhibit anything that shows any trace of green on the sepals (even though it may be very typical for that cultivar) because again, the judges don't like it (and may not be familiar with that cultivar) and will ding you. I also learned (from judge's comments as they judged various entries, while I was clerking) the crucial importance of properly primping and grooming an exhibit. Good grooming (or lack thereof) can literally can make or break a Best in Class or Best in Show exhibit.
So I have learned how to play the exhibition game (at least with daylilies), I concede the potential value in plant exhibitions for educating (or at least entertaining) the public, I find it interesting, informative, and educational to see entries of unfamiliar cultivars, and I confess that it can be exciting to win a rosette (even if it is almost by default, due to few entries in that class) - BUT it's not exactly something that I personally anticipate or am really very much into, even if I may exhibit a cultivar or two.
This should by no means be taken as a slur or condescension or anything else negative against anyone who participates in these exhibitions, either by volunteering their time, energy, and effort by serving as judges or clerks or general support, or by exhibiting. This is especially true of those exhibitors who bring a large quantity of exhibits to the show; they and their contributions are literally the backbone of such enterprises, and make or break it.
But what gives me the most pleasure, horticulturally speaking, is enjoying the yearly bloom season (of whatever plants) in my garden. It is watching the parade of irises come and go in spring, knowing that they are the harbingers of the daylily season to come. It is the sensual enjoyment of sniffing the fragrant 'Darkside', or admiring the harmonious combination of 'Darkside' with 'Afternoon Delight', or 'Navajo Jewel' (maybe) with a near-white rose. It is viewing the white 'Arctic Express' and 'Hidden Surprise' in the Moon Garden, at dusk. And later, come daylily season, it is in going out to the side yard garden and being greeted by the fragrant lemon blooms of 'Osterized' in June, followed by the towering (and also fragrant) blooms of 'Sears Tower' in July.
And what gives me the most anticipation is not a show, or the judges' decisions therein, but awaiting maiden bloom on a seedling. And what gives me the most thrill is not winning a purple ribbon or rosette (though that is a fine thing and justly worthy of pride, and yes, I have been proud of my few such ribbons), but seeing bloom on a seedling that is actually (for a change) pleasing to look at
, and knowing that you had some small part in bringing that about.
