Growing Irises Out East: Celebrating New Milestones

 by Heather and Alleah Haley

Heather's husband, Chris, once told her, "You can grow all of the irises you want if you can make money doing it." Four years after launching our backyard nursery operation, Heather is pleased to share, "We pulled it off!" Our multi-generational iris obsession produced a tiny net profit for the Broley Homestead at the end of 2023. Full disclosure: the effort yielded pennies per hour when all our time was fully accounted for. This is common for new farm enterprises, and we are pleased to celebrate profitability as a small business milestone. It gives us hope that maintaining an half-acre iris collection will be financially sustainable. 

In 2023 we took irises to our local farmers market for the first time.

The labels we use for potted irises in the spring are equally useful for bare-root rhizome sales in the fall


We continue to expand the number of community events and public plant sales we take irises to. Earlier this month, Alleah and Heather traveled to Laurel Hill, North Carolina, for an invited presentation to the Cottonland Garden Club. The presentation "Irises in the Garden: A Month-by-Month Calendar" was inspired by a question asked while Heather and Alleah volunteered at our local Cooperative Extension office. Another volunteer asked a deceptively simple question: "How do I care for my irises?" At the time, the best answer the mother-daughter duo could come up with was "It depends."

Irises are a relatively low-maintenance perennial, but they do require care. Our gardens are home to a curated collection of 1,200 named cultivars that span 15 of the 16 horticultural classifications recognized by the American Iris Society. What we do and when varies greatly depending on the quirks and preferences of each plant type. Having a knack for organization and creating educational materials, Heather crafted a region-specific, month-by-month calendar outlining the method to our madness. We have given this presentation several times to local libraries, and patrons say they loved it. Recently, Heather was invited to present the calendar program for our local AIS affiliate and the Cooperative Extension group that initially inspired the program. It will be an honor to finally share our best possible answer on a vast topic.

Volunteer work helps our business live its purpose: to preserve, support, and sustain. We thoroughly enjoy sharing our passion and love of irises with the public. Alleah, Chris, and Heather share personal commentary and stories about the plants, and customers seem to appreciate our insight. The following are some varietal notes about the top ten sellers for the Broley Homestead during 2023. 

'Dusky Challenger' (Schreiner, 1986)

In tenth place is a garden rockstar: 'Dusky Challenger'. The first time Heather entered an iris show, she brought a stem of this with her. The show was held in a mall; and while transporting her blue ribbon entry back to the car, several people wanted to buy the stalk. 

When we say this iris is a rockstar, we mean it! 'Dusky Challenger' won the American Dykes Medal in 1992. In 25 of the past 29 years, 'Dusky Challenger' was voted #1 as the favorite iris in Tall-bearded Iris Symposium voting. Alleah believes we could sell every rhizome of this iris we could grow; it's that good. 'Dusky Challenger', "probable child of the . . . famous 'Titan's Glory' (Schreiner '81), has all the outstanding qualities with more intense, deeper color saturation and even better, more highly refined form." [Perry Dyer, writing in the IRISES Bulletin No. 263 (October 1986)]. When she lived in California, Alleah routinely gave iris rhizomes to her coworkers. She rarely could convince folks to keep the irises name-labeled, but "the near-black one," be it 'Titan's Glory' or 'Dusky Challenger', increased so much with regular horse manure fertilizing that one recipient couple had it blooming all over their three-acre rural property in just a few years. 

'Bermuda Triangle' (Anna and David Cadd, 2000)

In ninth place in sales was 'Bermuda Triangle', a space-age border bearded (SA BB). While the general public tends to be somewhat reluctant to buy "novelty irises," 'Bermuda Triangle', with its horns at the ends of the beards, is a vigorous grower with a striking color pattern. It won an Award of Merit for border bearded irises from AIS judges in 2006. This award honors the top 1% of irises introduced during the previous three to five years. 

Broley Homestead is pleased to distribute this introduction of Alleah's close friends, Anna and David Cadd of Healdsburg, California, even more widely. 'Bermuda Triangle' increases well and thrives in the North Carolina climate. Although our peers on the East Coast often say that irises from the West Coast don't do well, this hasn't been our experience. It certainly isn't the case for this eye-catching median selection or many others purchased from or gifted by our West Coast friends.

Again and Again (Sterling Innerst, 1999)

In eighth place was reliable rebloomer (RE) 'Again and Again', a tall bearded (TB) iris. Our customers are really surprised when we tell them that some irises can bloom twice, both spring and fall; so reblooming is a strong selling feature. However, we like to share with customers that rebloom behavior requires both a genetic trait and favorable cultural conditions. When most irises are resting in the summer, a rebloomer is firing up for another round of bloom. Gardeners who provide nutrients and water to rebloomers in the summer are more likely to enjoy bloom again in the fall. 


'Stairway to Heaven(Lauer, 1993)

'Stairway to Heaven' placed seventh among our 2023 sales. This iris won the American  Dykes Medal in 2000. It tended to rebloom in California, mainly when grown under a nighttime security light, as Alleah did at her workplace. It isn't known to rebloom in North Carolina. One of Heather's friends planted it under the porch light at her back door, but this may not provide enough wattage to prompt rebloom. We can hardly wait to situate some West Coast rebloomers under a security light to see if we can get rebloom here.


'Sicilian Orange' (Michael Sutton, 2016)

Sixth place 'Sicilian Orange', also a TB, grabs public attention, whether in the garden or in a photograph accompanying the plant at an iris sale. The striking combination of deep orange and wine in this bitone is delightful. It won an Honorable Mention in 2018 and an Award of Merit in 2022, and is under consideration as an iris that deserves two (or more) growing spaces in our production field. We don’t have any pots of ‘Sicilian Orange’  available for 2024 because we sold every extra rhizome we had of this variety last fall. 


'Sharp Dressed Man' (Thomas Johnson, 2010)

'Sharp Dressed Man,' in fifth place, is a child of the 2010 American Dykes Medal winner 'Paul Black', and bears a similar but perhaps even more stunning red beard than that of its parent. It absolutely screams, "Look at me!" For those who appreciate irises that share names with song titles, this one is sure to make their list. This tall bearded iris forms impressive clumps with many increases in our production field and consistently produces bloom stalks we enjoy taking to spring iris shows. As you might expect, American Iris Society judges consistently cast votes for this one. 'Sharp Dressed Man' won the highest award specific to tall bearded irises, the John C. Wister medal, in 2016.


'Immortality' (Lloyd Zurbrigg, 1982)

Fourth place 'Immortality' (TB RE) is one of the most reliable rebloomers wherever we've seen it growing. Its hybridizer Lloyd Zurbrigg focused on breeding reblooming irises and 'Immortality' was one of his most successful introductions. Alleah recalls reading an account that 'Immortality' bloomed during five months one year in one garden. Our customers certainly picked a good one here! The pure-white self pattern coordinates well with other iris colors and patterns making it a wonderful addition to any iris collection.


'Gypsy Lord' (Keith Keppel 2006)

'Gypsy Lord,' was our third most frequently sold iris and is another striking American Dykes Medal winner, this time in 2015. Its red, white, and blue color combination has been a somewhat elusive goal of iris breeders, brought to fruition here by the highly honored hybridizer Keith Keppel. The red-orange beards against the white center and mostly blue falls quickly catch the attention of customers. Keith's creations won the American Iris Society's top award, the Dykes Medal, eight times over the period, 2004 - 2021. Except for 2021 when two Dykes Medals were awarded to make up for no awards at all during Covid year 2020, only one iris has been awarded the American Dykes Medal each year since 1927, and it was not given in several years for various reasons. 


'Carved Pumpkin' (George Sutton, 2012)

'Carved Pumpkin', an intermediate bearded (IB) iris, was our second highest seller. This iris increases well, so we had many pots and rhizomes to sell. Our cousin Wendy loves the color orange and, like the public, she is attracted to any iris featuring orange coloration. The color of iris blossoms is influenced by soil pH. Try increasing this by adding bone meal or decreasing pH by adding acid fertilizer such as azalea/camellia food to see which intensifies flower pigment.


'Titan's Glory' (Schreiner, 1981)

'Titan's Glory', another American Dykes Medal winner, this time in 1988, was our overall best seller in 2023. Like many of the Dykes winners, this tall bearded iris is a vigorous grower and produces many increases in our garden. The original Schreiner’s catalog described it as "a fantastically sumptuous silken Bishop’s purple self," and it is. 

We often wonder if Perry Dyer was correct in his assertion that 'Titan’s Glory' was one of the unknown parents of  'Dusky Challenger'. Genomic testing for irises is possible, and we know scientists in laboratories who could help. However, the price-per-sample is rather high and we would need to sell many more irises than we do now to absorb the cost.

For 2024, we continue trying new things and sharing the joy of irises. Heather spent the winter upgrading the Broley Homestead website, and Chris engineered new protective structures to transport plants to market. Alleah has been hard at work creating metal labels for guest irises at three gardens near us. All hard work, but each new milestone is cause for celebration.

Thank you to all who have helped us learn and grow.

Tom Craig in Three Acts

By Bryce Williamson

As I wrote in a blog about Sydney B. Mitchell, some of the important iris personalities of the past have faded from view and memory even though they were significant when alive and have contributed to the iris world through their creations and actions. Such is the case of Tom Craig (and family). The story of Tom Craig is like a play in three acts.

In the first act of the Tom Craig story, the focus is on Tom Craig as an artist. A graduate of Pomona College in the areas of botany and art, Craig gained a reputation as an upcoming artist in both oil and watercolor paintings as part of the California Group. Alfred Frankenstein, writing for the San Francisco Chronicle said that Craig was “one of America’s finest water colorists….the master of Mist and Water”. The phrase “master-of-mist-and-water” came from his technique of wet-on-wet, a style that he worked on continuously in California. Watercolors and oil paintings from Craig regularly appear on the market and prices run up to $5,000. Craig paintings are found in major United States museums including the Metropolitan Museum of Art.

In 1938 Tom Craig married Frances Stack. Both Frances and their five children (Tim, Ken, Ivan, Patricia Valesca, and F. Amoret) became an integral part of the iris hobby that turned into a business. The financial need to support his family led Tom Craig to teach at both the Chouinard Art Institute (later the California Institute of the Arts) in Los Angeles and the University of Southern California. Additionally, he grew irises for money, a hobby that continued throughout his life.

The second act of Tom Craig’s life happened when World War II broke out.  Craig applied to the War Department for a job as an artist war correspondent. He was hired in 1942 by Life magazine and was sent to Asia briefly. After his time in Asia, he was re-stationed in Italy to the frontlines, where he sketched and painted G.I.s in action.

Tom Craig’s third act took place after World War II, focusing mainly on botany and less on painting.

He moved with his family to Escondido, California, to a 250-acre (some sources say 350-acre) farm purchased before the war—land without a road or water. He turned to his love of botany and cultivated irises for the remainder of his life. He painted occasionally but turned the majority of his attention to raising hybrid flowers and experimenting in botany.

From this third act, the irises pictured below became important. Sadly, many of his irises are simply not cold-hardy enough to thrive in all areas of the country.

Looking at Craig parentages, he was using the best irises from his contemporaries. Irises from Hans and Jacob Sass figure in crosses as do irises from Fred DeForest, R. E. Kleinsorge, and Agnes Whiting. It can be said that he owed a huge debt to Mohr-Mitchell plants. Both named varieties and seedlings from Mohr-Motchell playing key roles in Craig's gene pool. Out of his work with Michell plicatas, Tom produced the early space age iris 'Bearded Lady' (T. Craig, 1955).

From his work with reds, 'Savage', 'Molten', and 'Bang' were widely popular and won AIS awards. 'Savage' proved to be an important parent for Tom’s friend Sanford Babson and figures in Schreiner irises. 

'Savage' (T. Craig, 1949)

'Bang' (T. Craig, 1955)

The early introduction 'Joseph’s Mantle' figures prominently in brown-toned plicatas. It was also a warm climate rebloomer and would even rebloom some years in New England. 'Gene Wild' was used by Schreiner's, Keith Keppel, and Gordon Plough. Ironically despite the name, Gene was female and part of the Wild and Son growers of daylilies and irises. That firm is no longer a family business.

A whole paragraph is needed for 'Mary McClellan'.  Registered as a Mohr-type arilbred and a winner of the C. G. White Award, it would not qualify for that award today since it lacks the required arilbred characteristics; however, it was used by many, including myself, in hybridizing. In the blue, violet, and white colors, his white 'Patricia Craig' (1962) also was widely grown.

'Mary McClellan' (T. Craig, 1952)

Tom worked in other classes of irises beyond tall bearded. His 'Moonchild ' won the Sass Award and when that award was raised to medal status by the AIS, it won again.

'Moonchild' (T. Craig, 1955)

Although Craig only introduced eight spuria irises, his nearby Escondido neighbor Walker Ferguson used several in his groundbreaking work with spurias. 'Blue Pinafore' (1950)  was one of the Craig introductions used.

For his work with irises, the American Iris Society awarded him the Hybridizer's Medal in 1962

'Blue Pinafore' (T. Craig, 1950)

One of the surprises of this piece is that I had expected to find many of Craig’s warm climate reblooming irises in the parentages of newer irises. So far, my research has not found that to be true.

In the post War World II boom in Southern California as agriculture gave way to housing, Craig ultimately sold the Escondido property and moved to Hubbard, Oregon. In 1969, the catalogue was done and irises ready to be sold when he suddenly died of a heart attack. Frances and family continued the business that year.

Schreiner's went to the garden and acqired over 20 seedlings that they later used in hybridizing, but the seedlings were without parentages. I have been told that his children and grandchildren are trying to find Craig introductions, but my efforts to contact his children have come to nothing. There is even a story that Craig may have raised some irises during the move from California to Oregon on Sanford Babson’s property in Covina, California, but no collaboration of that story has surfaced.

Tom Craig's influence on the world of irises continues today even if his memory has become a bit misty despite his wonderful efforts to popularize irises; his influence on painters through his years at Pomona College, Occidental College, the University of Southern California, and the Chouinard Art Institute is undeniable. He had been a major influence on the California Style, with his wet-on-wet technique.

Spring Beginnings in Australia

by Mel and Bailey Schiller

Harvest Moon over a field of irises

A wonderful sight is the September Harvest Moon in Australia: September 29th 2023. Lighting the way for the next 6 months will be extra daylight that helps us get our chores completed. We give thanks and show gratitude for each of you that join our family on our bearded iris journey. We wish you all fulfillment and happiness in your lives as we enter the summer months in Australia.

Bloom season has started strong and early for us down under. Dwarf bearded irises have been blooming for the last 3-4 weeks. Over the last week or so the taller classes have started blooming as well. 


Miniature dwarf bearded iris 'Ribbit' (Johnson, 2020)

Opening on the first day of Spring was probably the best formed and most interesting miniature dwarf bearded iris we grow: the green-toned beauty 'Ribbit.' A fantastic grower and reliable bloomer, it has been a joy to grow since we imported it into Australia in 2020. 

Miniature Dwarf bearded iris 'Twinkle Little Star' (Black, 2020)

Following closely was another miniature dwarf; 'Twinkle Little Star'. This iris has been a very good performer for us since we imported it. Generally, dwarf varieties don't perform very well for us here in South Australia. Our Winters don't get cold enough for these little irises to truly thrive. Yet, we persist because we think they are absolutely adorable. We have also been hybridizing dwarf iris and selecting for those that perform well in our climate. 

Standard dwarf iris' Tallica' (Blyth, 2015)

Another iris blooming right at the beginning of Spring was 'Tallica.' Although this Australian-bred standard dwarf has never reached its registered height for us, it is a fantastic performer in our gardens. As you can see by the photo, it puts on a wonderful display!

Standard Dwarf bearded iris 'Done Me Wrong' (Baumunk, 2009)

'Done Me Wrong' is not the greatest performer in our climate. However, we love the look of large beards on a dwarf iris, so it gets to stay around. It is always very early and one of the first standard dwarfs to bloom.

Intermediate bearded iris 'Plasma' (Blyth, 2007)

Although not registered as a rebloomer, 'Plasma' has been a reliable rebloomer in our garden since we first acquired it. It has bloomed sporadically over Autumn and Winter and sent up its first Spring stems last week. Very popular with garden visitors, you can see why!

Intermediate bearded iris 'Lumistreak' (Black, 2022)

Imported last year from America, intermediate bearded iris 'Luminstreak' is proving to be an overachiever, blooming in its first Australian Spring. Normally, imported varieties only bloom in their second or third Spring, once they acclimate to our conditions. 


Miniature tall bearded iris 'Tic Tac Toe' (Johnson, 2010)

The best performing miniature tall bearded iris that we grow, 'Tic Tac Toe' always puts on a spectacular display. Most years it also blooms quite heavily in Autumn. 

Miniature tall bearded iris 'Say Red' (Craig, 2008)

'Say Red' is quite a vigorous bloomer for us, and it has been difficult to grow a decent clump. We have yet to have any success in using it in our hybridizing.

Arilbred iris (OGB+) 'Emerald Fantasy' (Tate by Shepard, 1983)

We absolutely adore the dramatic arilbred 'Emerald Fantasy.' If only this colour and pattern could be replicated in tall bearded irises. The arilbreds are a bit behind this year, normally starting to bloom at the beginning of September. We don't mind though--as there is more choice of iris to hybridize with!

Arilbred iris (OGB) 'Zizah' (Rich, 1983)

'Zizah' was the first arilbred to bloom this Spring, we almost didn't notice it as the stems are quite short. A classic colour combination in arilbreds, stunning!

Border bearded iris 'Stegosaurus' (Sutton, 2012)

'Stegosaurus' is the first border bearded iris to bloom each year. We love the unusual hard spikes along the edge of the standards. We have tried using it in our hybridizing with limited success. It is a very difficult parent but will occasionally set a pod. 

Border bearded iris 'Smiling Bright' (Ryks, 2020)

Close behind 'Stegosaurus' is the South Australian hybrid 'Smiling Bright'. A fantastic grower and increaser, it puts on a massive display of flowers each Spring. It makes quite a statement!

Blyth seedling A157-A:(X262-X:(Early Encounter sib) X Kiss The Princess)

Barry is known for breeding extremely early tall bearded varieties and this is one the earliest to date. Starting to bloom at the very beginning of Spring, it is probably not suitable for many American gardens but is perfect for us here in Australia. Late bloomers tend to burn in our hot Australian sun, so Barry worked on extending our season out in the other direction. This seedling has passed all the checks and will be introduced next year. 

Tall bearded iris 'Zofonic Dancer' (Schiller, 2022)

This one of Mel's introductions, 'Zofonic Dancer,' has been blooming since the end of July. We aren't sure if we should characterize this as extremely early Spring bloom or a late rebloom, as this variety has never rebloomed for us in the past. Nevertheless, it has put up more stems since Spring has started and will probably be in bloom for at least another month. 

Bloom season is exciting as we wander our field and garden with child-like awe, excitement, and exhilaration. Checking for new blooms, being reminded of varieties long forgotten about, and (of course) enjoying the new varieties that have been imported. We look for pollen and dream of what could be or should be---dreams that one day will come to fruition. Bearded iris season is the best!

Happy Gardening!

The American Iris Society Announces the 2023 Caparne-Welch Medal Winner

'BLACK OLIVE'

The Caparne-Welch Medal is restricted to miniature dwarf bearded (MDB) irises. It is named in honor of William John Caparne (1855-1940) and Walter Welch (1887-1980). Caparne worked extensively breeding various dwarf iris species and was the first iris hybridizer to concentrate on smaller irises. Most of the dwarf iris cultivars grown in gardens in the first quarter of the 20th century were products of Caparne's hybridizing efforts. Walter Welch was the founder of the Dwarf Iris Society. After moving to Middlebury, Indiana, he met Paul Cook and began hybridizing irises. He shared Cook's enthusiasm for dwarf irises and set out to develop new forms for the garden.

Previous awards winners can be found at https://wiki.irises.org/Main/InfoAwards.

Incredible Arilbreds

by Jeff Bennett

An incredible bed of arilbred irises in bloom

Among the many types of irises, there are categories of irises called arils and arilbreds. Now without getting too technical on the differences between the two, I’ll just basically say that arils are a group of wild species irises from the eastern area of the Mediterranean, including Turkey, Syria, Israel, etc.; and the middle of Asia where Regelia-type irises are from. Their exotic blooms, generally one flower per stalk, are breathtaking to see. Their growing requirements are also hard to understand for gardeners that like to water their plants and take great pleasure in doing so. Watering aril irises in the summer probably means you won’t see them next spring as they will succumb to rot.

Home gardeners can obtain that exotic iris "look" with easier cultural requirements when hybridizers breed arils with the bearded iris cultivars we know and love. These irises are called "arilbreds." They come in all heights, from dwarfs to talls. Depending on which species were crossed, their offspring display different heights, petal shapes, and distinctive blotches or veining. Some people are afraid to try growing arilbreds and I don’t understand why. Maybe it’s the word "aril" in the name? I received my first arilbreds in 2017 and grew them for the 2019 American Iris Society Convention in San Ramon, California. I planted the arilbred guests right in line with the other bearded irises. I was not told to treat them any differently. I was pleased to watch 'Galaxinia', 'Heart of Hearts', 'Perry Dyer', and 'Red Ahead' as they prospered and were standouts at the convention. These exotic-looking irises grew just as big as their bearded half-cousins planted next door.

Arilbred iris 'Perry Dyer'

After seeing such interesting arilbreds at a local show put on by the Mount Diablo Iris Society, I decided to plant a couple of beds dedicated to arilbreds. Tracking down arilbred irises is not the easiest task, as most commercial iris gardens only sell a few (if any). Then I discovered that the Aril Society International (ASI) has an annual rhizome sale every July. Only members can purchase during this online sale, so I joined and diligently made my selections. The delivery of 40 or so rhizomes arrived a couple weeks later. In general, arilbred rhizomes are smaller than regular bearded irises, so don’t be surprised by rhizome size. Their striking flowers make up for this in a big way.

In late July 2021, I received my second order from ASI and some from other sources I could find. New beds prepared for just the arilbreds were ready and plants were transferred from their pots (I always plant my orders in pots so they can get a good start). By late winter 2021 to early 2022, all the arilbreds were in the ground in alphabetical order. That summer they were increasing like gangbusters! I knew that the bloom in the spring of 2023 would be excellent.

 'Kalifa's Robe' getting ready to bloom in January 2023

Fast forward to January 2023. After the wettest January anyone in the San Francisco Bay Area could remember, not only the first arilbred,  but the first iris bloomed in the garden on approximately January 24. 'Kalifa’s Robe' started it all. A huge purple flower with a dark signal blotch. Then 'Warrior Prince' and 'Desert Snow' bloomed on February 9. 'Noble Warrior'  bloomed on March 14. By March 18, new varieties were opening daily. Arilbreds are early bloomers compared to tall bearded irises. The last photo I have of an arilbred in bloom was around May 15. So almost four full months of arilbred bloom is what was achieved at Dry Creek Garden in Union City California in 2023.

Arilbred iris 'Diamonds and Rust' (E. Jensen, 2017)

Arilbred iris 'Rosy Celebration' (Tasco, 2021)

But not to be outdone, 'Lu’s Child' and 'Pashtun Princess' were in rebloom by June 13. The first bloom for 'Kalifa’s Robe' lasted a full 90 days and then got going again by sending up three more bloom stalks in late May.
