There was a discussion on "Pineappling" Chuck Chapman's FB page. Basically he calls it an imbalance of plant signaling and is involved with the start of growth combined with having appropriate amount of chilling. Plants have a "computer" system for flowering, with a number of genes that are involved in sensing the environment and promoting growth.. He goes on to say that it's a fine balance that can get disrupted when there are conflicting signals (grow vs not yet!) when weather conditions are not normal.
I don't know if this is what is causing your problem, but I've noticed a lot of wacky behavior in my Iris beds this year.
I'd like to know just what the heck is going on here..
I've got a couple that are doing this.. The rhizomes feel firm... They are both established clumps... I did pry off a rhizome or two to share from both this past year. I like to think I'm pretty careful when I do this.. but I'm trying to find commonalities between the two... They are in completely different areas of the garden with different types soil.
