From “Bearded Irises in Bed and Border” in Growing Irises by G. E. Cassidy:
“As a result of the dramatic developments in bearded irises… there is now available a fabulous range of flowers which must come as a revelation to those who still think of irises as ‘blue flags’….
“First as to colour — there are the irises of one colour, known as selfs, ranging from white to black through the rainbow with dark, light and pastel shades of each tint. Then there are the ‘amoenas’ with white or near-white standards and coloured falls, the ‘neglectas’ with light-blue standards and purple-toned falls, the ‘plicatas’ with light background overlaid with veining and stitching of a darker colour and the ‘variegatas’ with yellow standards and red-brown falls….
“Nowadays there are infinite variations of these basic themes with every sort of colour combination and with often brilliantly coloured and contrasting beards. In form and size, too, the bearded irises have changed almost beyond recognition and it is a far cry from the old drooping falls and floppy standards to the wide, flaring and ruffled falls and domed standards of the modern [tall bearded irises].
“Although suited to many applications in the garden, the bearded irises are seen at their dramatic and dazzling best when massed together in formal beds or borders. Here the range of colours can be seen to advantage, use can be made of variations in height to produce a graded effect and of the differences in flowering times to give a long flowering period….”
From “Purple Irises” in The Collected Poems by William Kean Seymour:
These purple flags in fancy seem to me
Delicate dames with their attendant squires โ
Green-garbed and slim โ who do their just desire:
Softly and well, and worship silently;
Or they are pools in a sun-smitten sea,
Deep hid in quietude of mirrored fires,
Decked with rich weeds and iridescent spires,
Shells and smooth stones and the anemone….
Hello!
This is the second of three posts with images of purple-toned irises from Oakland Cemetery that I photographed earlier this year. The first post is Iris Purpleness (1 of 3).
Of the four irises featured in the three-post series, this post includes these two…


… as a way of showing the difference between a single-colored self iris (on the left), and a bitone iris where the standards are a lighter version of the same colors in the falls. This bitone also produces a very large flower, something evident from the fact that I took the two photos above from approximately the same distance and focal length.
The bitone’s translucent standards let light pass through, which results in colors shifting between blue and violet depending on how much sun was present when I snapped the photos, as well as what direction the light was coming from. While it’s possible to color-correct them in Lightroom so that the standards colors match in all the final photos, it’s more accurate to try and respect the lighting conditions. One editing trick I use here is to adjust white balance so that the surrounding green leaves — rather than the flower — are rendered as consistently as possible across all the photos. Since white balance adjustments affect the whole photo, this lets the purple colors fall naturally into the ranges that would have been present at the time, regardless of how lighting conditions varied. Green on opaque leaves like these is a color we intuitively recognize as accurate or inaccurate, so it can be used as a visual anchor for correcting white balance and ensuring that the color relationships throughout the image are accurate.
From my observations, the bitone iris produces plants whose height is about the same for each stem, and it would probably be classified as a medium or intermediate bearded iris. The self iris, on the other hand, produces stems of varying heights — as the photos illustrate — often in clusters where some short stems surround one or two taller ones, as in this photo where it’s earning its designation as a tall bearded iris.

Its flowers — even the shorter ones — exceed the height of nearly all its leaves, a convenience for any photographer who wants to focus on the flowers and leave out the leaves. Such heights also make this iris suitable for use as shown in my photos: positioned against a stone wall and in front of shrubs to create horizontal and vertical visual interest with colors and shapes that both complement and contrast with the landscaped surroundings.
Thanks for reading and taking a look!
