Jude it is simple and sad. Hybridizers sell new iris based on a picture of 1 or 2 flowers. They could be breeding for sturdy stems that do not flop, but that is not lucrative. Some do and many do not flop. You best bet is to ask around at your local Iris club which cvs stand up well. Join the club, too. Surprising what their experience can tell and most are eager to share. Rebloom- Most new reblooming hybrids are reliable in CA and OR where they originate. Otherwise it is roulette. There’s two choices: 1) Ask around at Iris club as above or 2) order from local hybridizers who claim rebloom. Mostly it is a delicate balance of climate, watering and fertilizing for best results. and a final piece of advice, don’t believe the hype. Buyer beware. Good luck Jim W.

And, is there a quick and easy method to avoid this - other than staking? Also - what's the best way to get rebloomers to rebloom? I have a lot of rebloomers that do not rebloom when left alone.
