Proportion, Proportion, Proportion

 by Tom Waters

There is no excellent beauty that hath not some strangeness in the proportion.

                —Francis Bacon

It seems like devotees of the dwarf and median irises, myself included, are always talking about proportion. All the parts of the stalk, we are told, must be in proportion: the height and width of the flowers, the height and thickness of the stalk, even the leaves. Indeed, the American Iris Society’s Handbook for Judges and Show Officials gives measurements and ratios to define proper proportion for each class.


I’d like to raise a philosophical issue about proportion, and how it relates to two iris classes in particular, the border bearded (BB) and miniature dwarf bearded (MDB). These two classes face a similar problem: most BBs are produced by crossing tall beardeds (TBs), and most MDBs are produced by crossing standard dwarf beardeds (SDBs). Since the genetic background of these classes comes mostly from a different, taller class, it is not unusual to find flowers that are large, even when the height of the stem is short. Purists are very bothered by this situation, but short irises with large flowers seem to be popular with iris lovers and even judges. Are the many people who enjoy large-flowered BBs and MDBs just wrong? Should they know better?


The philosophical issue is this: is “good proportion” objective? Is there some numerical ratio of stem, flower, and foliage that is aesthetically optimal? Or is it just in the eye of the beholder? If it is just a personal, subjective preference, then the admonitions in the Judges' Handbook start to seem a bit arrogant and elitist. The classic example of a subjective judgment becoming judging gospel is the case of haft marks. In the mid-20th century, haft markings were the “fault” that everyone seemed obsessed with in TB irises. Yet, what if I think haft marks are interesting or pretty? Is this any different than preferring yellow to blue, or preferring plicatas to selfs? The condemnation of haft marks reflects the struggles of hybridizers. In those early years, it was very difficult to breed a true, clean, self-colored iris. Haft marks seemed to always turn up and distract from the desired purity. So the frustration felt by hybridizers was transformed into an esthetic standard that was promoted as something objective and universal. Once clean selfs were achieved, then people could start to enjoy haft marks for being “something different”!

Many, many “rules” that are enshrined in the Judges' Handbook are relics of the personal goals and frustrations of earlier generations of hybridizers, even though they are presented as objective aesthetic truths. I think proportion is one of those things. I say this despite the fact that I, personally, dislike large-flowered BBs and MDBs. If a BB blooms in my garden with TB-sized blooms and thick, coarse stalks, it does not stay here another year, no matter how pretty the color or form. However, in all honesty, I have to describe this as a personal preference.

Allium karataviense

If there were some objective, universally valid, proportion of bloom to stalk that looks best to everyone, then we would expect it to apply to all kinds of plants. But in fact, we enjoy flowers with all different ratios of bloom size to stem height, without thinking twice about it. Consider two alliums I grow: A. karataviense produces enormous globular flower heads right at ground level. I enjoy it immensely. A. caeruleum produces small, airy blue flower heads on tall slender stalks. I enjoy it also. These two could not be more different. And neither has the proportion of a “good” bearded iris. In fact, I think an iris proportioned like either of the alliums would inspire revulsion in a typical iris judge.


Allium caeruleum


It may seem like I am now arguing for a free-for-all approach to proportion. If it is all subjective, why should we worry about a BB with TB-sized flowers or an MDB whose bloom is twice as wide as the height of the entire stem? Perhaps judges should focus on more objective things, like plant vigor and bud count, and let people enjoy different proportions, just as we enjoy different colors?

No, that is not the approach I favor, although I think the argument should be made from time to time to provoke thought and debate. I believe there is a good reason for harping on proportion in the dwarf and median irises, but I don’t think it has anything to do with some objective, universal standard of beauty.

What then? If small-flowered BBs and MDBs are not objectively superior to large-flowered ones, why should we care at all? I think the answer lies in something else: class identity. Consider this: although they fall in the same height range, miniature tall bearded (MTBs) are “supposed” to have smaller flowers and more slender stems than BBs. If one proportion is more attractive, shouldn’t all classes aspire to that same proportion?

To most median aficionados, the answer is obvious: each class has its own aesthetic ideal. We like the fact that BBs look different from MTBs. They are like two different styles of music. In our minds, we may have a picture of the ideal, the prototype, as it were, for each class. It is these mental prototypes that give each class its identity, its center of gravity in the great sea of diversity that hybridizers have produced for us.

So I think what we are complaining about when we complain about out-of-proportion BBs or MDBs is the erosion of the identity of the class, the weakening of the mental prototype. The reason I have singled out BBs and MDBs is that the irises in these classes are mostly “spill-overs” from TBs and SDBs, respectively. There is a relentless pull on these classes to merge together with the larger classes that give rise to them. If a BB is just a TB that is short, why not call it a TB?

Some have sought to strengthen the identity of these classes through breeding. Lynn Markham’s BBs
were produced intentionally to reinforce the distinct identity of the class. Ben Hager used a similar strategy to reinforce the identity of the MDB class. These were valiant efforts, but they were not sufficient to turn the tide. So many people are crossing TBs that the “accidental” BBs that emerge from TB crosses far outnumber the “intentional” BBs that are produced by the small number of breeders who are interested in the class as an end in itself. Exactly the same is true of the MDB class.
I wish I could end on some profound revelation or recipe for solving the conundrum of these classes, but I don’t think there is one. What it comes down to is simply this: do we (the entire iris-loving public, hybridizers, and judges) care enough about the identity of these classes to insist on maintaining their integrity? Perhaps we don’t. It’s not obvious that we “should”, after all. If we like the irises we’re growing, even when they depart from that mental prototype, maybe that is fine. Collective opinion is not something that can be easily predicted or controlled. It just is what it is.

But if nothing else, perhaps we can shift the language of the conversation a little. Instead of talking about “good” or “bad” proportion, perhaps we can talk instead of class identity. That seems more accurate and to the point.

Borderline Cases


by Tom Waters

There are three classes of median irises that span the interval between the standard dwarf bearded (SDB) and tall bearded (TB) classes. The intermediate bearded (IB) are mostly the result of crossing TBs with SDBs, leading to plants intermediate between the two, both in height and in bloom season. The miniature tall bearded (MTB) come from varied backgrounds, but must meet exacting standards of delicacy in height, flower size, and stalk proportions. The final class, the border bearded (BB) are derived almost exclusively from the TBs, but with height less than the 70 cm (27.5 inches) that is the boundary between the BB and TB classes.

The BB class is unusual in that it has no real “center of gravity” of its own; rather it represents the smaller “tail end” of the TB class. Many BBs are registered at a height of 27 inches, just barely below the upper limit of the class, and are hard to distinguish in practice from TBs at the lower end of the TB height range. One might ask if there is really a need to place such irises in a separate class.

Proponents of BBs have long had a vision of the class that sets it apart from the TB class. An ideal BB is not just a TB that is an inch or two shorter; rather, an ideal BB is a reduced TB in all its dimensions and proportions, including foliage, branching, flower size and form. While it is not intended that they be as delicate as MTBs, they ought to be “halfway there”, as it were – they should be esthetically medians, instantly distinguishable as diminutive and elegant irises in their own right. Part of their value comes from being useful in garden design in situations where TBs would be out of scale or overwhelming. They should be more about charm than grandeur.

Some of the best median hybridizers have pursued this ideal with great care, selecting plants for introduction that are modestly proportioned, perky, and might more easily be mistaken for IBs or MTBs than for TBs. Early BBs like ‘Frenchi’ (B. Jones, 1959) and ‘Tulare’ (M. Hamblen, 1961) were exemplars of this ideal in their time, as was ‘Brown Lasso’ (Buckles by Niswonger, 1975) which was the only BB to win the American Dykes Medal. ‘Cranapple’ (Aitken, 1995) is a worthy example of more recent vintage.

 This is difficult work, and not always appreciated; many people buy BBs just as they do TBs, by looking at the catalog “glamor photos” of single blooms and choosing exciting colors and patterns, with little attention to plant proportions or esthetics. A large, blousy iris with the latest TB color pattern that does not meet the BB ideal may sell more than a carefully selected, lightly ruffled, charming BB in an unexceptional yellow, violet, or white.

One might argue that this doesn’t matter in the big picture of things. People like what they like, and if they enjoy an iris, who cares about its failure to meet some elitist ideal?  On a case-by-case basis, I think that is a valid perspective. Where it becomes problematic is when the notion of the class becomes so blurred that it ceases to convey anything clear to gardeners, and those seeking smaller, well-proportioned medians can’t trust the BB designation as meaningful.

'Oops' (Jim and Vicki Craig, 2003),
a BB from tetraploid MTB breeding
We all have a role to play in maintaining the distinctiveness of the BB class. Hybridizers can work more with lines that are intentionally devised to produce BBs, rather than taking most of their BB introductions from crosses intended to produce TBs. Tetraploid MTBs and smaller bearded species can be used to “tame” the TB genes and keep plants in scale.

Judges must strive to be more scrupulous in maintaining the standards of the BB class. Alas, color novelty and hybridizer reputation often bias judges away from a more sober consideration of shape and proportion.

Finally, buyers can reward hybridizers who keep the BB ideal in mind. Best of all is to buy BBs you have seen growing in a garden, and which you know to be consistently diminutive and in proportion. If you do buy “sight unseen” (as I often do), give preference to BBs registered in the 20-24 inch range, rather than 26 or 27 inches, as so many are. I also check pedigrees, looking for a preponderance of BBs, MTBs, or SPX irises in the background of a new BB. Finally, even a single-bloom photo can convey information about the scale of the plant, if you know what to look for. A bloom that is perky, flared, and not too ruffled is more likely to be in scale than one that is more flamboyant but not so flaring.

I have chosen not to use this blog post to give examples of modern BBs that I think are particularly fine or particularly poor examples of the class ideals; that is for each person to decide for themselves.

The BB class need not be just a spillover for short TB seedlings; it has much to offer the discerning gardener. Wonderful irises come in all sizes!
