One more point about herbicide damage... I've had it affect only a couple rhizomes of a clump, making some stalks color challenged and others normal. I'm thinking it has to do with how many rhizomes are attached to each other.
Last year I had a lot of Swan-necking and extra or missing petals.. extra beards.. We had a freeze in December, then 70's and 80's in January and February. This year, we had the same, except for no cold.. Everything is off schedule and confused, but I've had very little distortions this year.
