When do tall bearded irises bloom? It seems like such a simple question, but in reality, it is complex and you will get different answers from different people. There is the problem of which part of the country you live in, because our seasons differ widely. Today I will tackle a different issue- the designations themselves. What I say here may be discussed (and cussed!) but after consultation with a few other hybridizers, here is, to the best of my knowledge, an answer to the question.
I have been hybridizing and introducing irises for 33 years. I am a Judge Emeritus with 25 years of iris judging experience. I have never heard of or attended a judges training, course, or session that went into detail about bloom periods or how to designate a given period of bloom to a new iris, but some things we can probably agree on.
We can all agree that there are three basic bloom period designations for all irises. These are early, mid, and late. They are listed in the registrations as E, M, and L. If this was it, there would be no need for this article. It's what we add to those three designations that causes confusion.
My 2013 introduction, 'La Di Da', is a late season bloomer.

'Paul Black' is another late season bloomer.

'Cowboy in Black' is a mid-season bloomer, as is 'Paris Fashion'.

'Acoma' is an early bloomer, as is another of my 2013 introductions, 'Star Voyager'.

If an iris blooms before any other iris, or after all of the other irises, sometimes the letter "V" is added. That gives you very early (VE) and very late (VL). That's still pretty basic stuff.
Griff Crump's 'Bulbul Ameer' is a very late blooming iris.

'Footloose' is very early.

Stay with me, it gets better or worse, depending on how you look at it.
A number of iris registrations list bloom times of EM or ML. Now things are getting a little more confusing, but here comes my take on this group. The second letter is still the basic time of bloom, so EM is in the mid bloom season, but a little earlier than most. However, in researching this group with other growers, I found out that some hybridizers use these designations (EM or ML) to tell the public that the iris blooms in both the mid and late bloom seasons. For instance, Schreiner's Iris Gardens uses the designation EML for an iris that opens blooms throughout the entire season. I will be honest, I have never registered an iris this way, and I had never thought of doing it in this manner.
My 'Kansas City Star' blooms early in the midseason.

'Pansy Parade' is registered as mid-late, and it blooms in the late part of the mid-season, according to Walter Moores.

'Saturday Night Live' is registered as EML, because it blooms throughout the entire season, according to Schreiner's.

To conclude the discussion, some hybridizers use the V, E, M, and L bloom time designations in combination to show an extended bloom time, and others to narrow down the exact time of bloom. What fun it would be to order a number of irises with the same listed bloom time and grow them yourself to see which is which.
In your experience, do irises with designations of EM, ML, or EML bloom for longer periods of time? Please leave a comment in the box below so that others can have the advantage of your experience.
Part II will address bloom height, so stay tuned.
