Location, Location, Location

By Bryce Williamson

Although I have been growing irises for over 55 years, I learn something new every iris season, or a lesson from the past is reinforced. In the last few years it is the term “location, location, location” and my discovery that it not only applies to real estate but also to gardening.

'Lavender Moonbeams'--Rick Tasco image
Two years ago, I decided to add three I. unguicularis, sometimes called the Algerian iris, to the garden, but my acquiring the plants coincided with my breaking six ribs and having to find a spot for the gardeners to plant them while I healed. The location was not ideal—my first lesson was that I should have found a location where I walk every day, not in a bed where I can go days without looking at the plants. The second thing I learned, and it is a recommendation for other gardeners who might like to grow these winter flowering irises, was find ‘Lavender Moonbeams’ because it flowered well.

Last year I made the decision to move the irises from the backyard into the front yard. No irises have grown there in seven or eight years and I expected them to do well in this new location. I had learned my lesson from the past and fertilized more heavily and add organic matter to the soil. That we did by moving 7 yards of potting soil mix into an area 600 square feet and a fifty pound bag of 15-15-15 was also spread over the area; however, I tend to over plant and as a result, I ran out of room and needed to plant my arilbreds in a different bed by the walk.

I had Reynaldo hand dig the bed with a bag of potting soil, but as the arilbreds grew and then bloomed, they bloomed poorly. My lesson was that they needed more fertilizer and one bag of potting soil for even that small area was not enough. I’ve also learned that my tendency to want to replant 4 rhizomes of a variety needs to be curbed—I may have to settle for 3 rhizomes! I will have to watch myself or the 1200 square foot area we are preparing in the backyard will not be enough.

I have always thought that where I bought plants and bulbs determined the quality of the product. A couple of years ago, I decided to add some reticulates to the garden and, for once, I got the location right—along the front of the sidewalk where I walk at least 6 times ago. I picked up a cheap bag of Iris reticulata ‘Harmony’ from Costco and went to the most expensive and best of Silicon Valley’s remaining nurseries—the dwindling number of plant nurseries here is another story—for other colors and into the ground they went. I’m on the second year and ‘Harmony’ has bloomed well, though I learned that I should have planted the bulbs more closely together, and it is thriving, but the more expensive plants have grown and only thrown up a couple of flowers. There does not seem to be a tight connection between price and quality of the bulbs.

Sometimes I get the location right by mistake. Every few years, I scrounge the nurseries for Dutch iris, buying a dozen of each variety that I can find. They do well the first years, but fail to naturalize for a variety of reason. The amazing exception is ‘Sky Wing’, a soft lavender-blue that loves it location and flowers every year. It is planted at the edge of the water line for the sprinkler and I thought that location would be a kiss of death, but it likes it there. A large rock anchors that corner of the rose bed and that may help with Sky Wing. (Note that there is a Siberian called Sky Wings too).

With more than fifty springs under my belt for growing irises, each year I learn something new.

Three Twentieth Century Women Iris Hybridizers

by Jean Richter

This is an introduction to three women iris hybridizers from the 20th century who are perhaps not particularly well known, but all created iris of great beauty.

Our first hybridizer is from the earliest era of the American and British Iris Societies, in the early part of the 20th century.

Miss Violet Insole was a horticulturalist from Wales with particular interests in alpine plants and iris. She was born in 1883, and by age 21 was an accomplished horticulturalist, contributing to The Flora of Glamorgan at the invitation of the Cardiff Naturalists' Society.  During World War I she served in the British Red Cross Society Volunteers, and from 1917 was Quartermaster and Officer in Charge of the Llandaff Red Cross Hospital. In the 1920s she traveled abroad to New York, Jamaica, and South Africa to collect plant specimens.

Miss Insole was an early member of the British Iris Society, and was listed as a member by 1924, two years after its founding. She became a successful exhibitor in their shows, garnering many certificates and medals. In 1930 she gave the Society the Insole Challenge Trophy, awarded for a display exhibiting the decorative value of the iris.

Miss Insole was also an accomplished iris breeder. Although she introduced relatively few varieties, many of her varieties were award winners. Perhaps her most famous introduction, which is still widely available in commerce today, is 'Dogrose' (Insole 1930). This tall, stately iris has great impact in the garden.

                                                 'Dogrose' (Insole 1930)

Less well known, but still available in commerce, is the exquisite 'Golden Flare' (Insole 1931).

                                             'Golden Flare' (Insole 1931)

Sadly, Violet Insole passed away after a brief illness at the young age of 49 in 1932. At the time of her passing she was just coming into her own as an iris hybridizer, and surely would have introduced many more excellent iris had she been afforded a longer life.

My research has turned up only the barest of information about our next hybridizer, Luella Noyd. She was born in Spokane, Washington in 1903, and apparently lived in the eastern Washington area her entire life. Her iris hybridizing was concentrated on tall bearded iris, but she also introduced arilbreds, border bearded iris, and an intermediate bearded iris. I first encountered her iris with the lovely space age iris 'Horned Sunshine' (Noyd 1968). She continued Lloyd Austin's work with horned iris by using one of his space age introductions as a parent to 'Horned Sunshine.'

                                       'Horned Sunshine' (Noyd 1968)

'Fluted Lime' (Noyd 1966) is a greenish-yellow self.

                                               'Fluted Lime' (Noyd 1966)

Mrs. Noyd named several iris for her home town of Wenatchee, Washington. Here is her blue introduction 'Wenatchee Skies' (Noyd 1963).

                                         'Wenatchee Skies' (Noyd 1963)

Her lovely introduction 'Striped Butterfly' (Noyd 1958) has aril ancestry and could have been introduced as an arilbred, but she chose to introduce it as a tall bearded iris.

                                            'Striped Butterfly' (Noyd 1958)

Luella Noyd passed away in 1980 at age 76.

Walter and Luella Noyd circa 1960

Our final hybridizer achieved considerable acclaim in the iris world during her long life. Melba Hamben was born in 1910 in Utah. Her interest in flowers, and iris in particular, was a lifelong passion. She started growing iris in 1936 and began hybridizing in 1943 under the mentorship of Tell Muhlestein. She married Jim Hamblen in 1927 and as he shared her love of flowers, together they  ran Mission Bell Gardens.

Melba was a lifetime member of the American Iris Society, an award she received by getting the most new AIS members to join while she was Regional Vice President of AIS Region 12. She served on the AIS board of directors for many years, and as president of the AIS Foundation. She co-edited the AIS book The World Of Irises - it was one of her personal triumphs when the book was published.

Melba received many awards and accolades for her hybridizing accomplishments, including a feature in Life Magazine, honorary citizenship to the states of Arkansas, Oklahoma, and Texas, and the key to the city of Tulsa, Oklahoma. She was the first woman (and one of few Americans) to receive the British Iris Society's Foster Medal. She also received the Gold Medal from the American Iris Society.

Melba hybridized mainly tall bearded iris, but also introduced miniature dwarf, standard dwarf, intermediate, and border bearded iris. Her many creations include the beautiful pink and yellow blend 'Valimar' (Hamblen 1958).

                                               'Valimar' (Hamblen 1958)

Here is the lovely yellow 'Royal Gold' (Hamblen 1966).

                                          'Royal Gold' (Hamblen 1966)

One of her later introductions is the beautiful plicata 'Capricious' (Hamblen 1981).

                                            'Capricious' (Hamblen 1981)

Melba Hamblen passed away in 1992. She is remembered as compassionate individual who never hesitated to offer her knowledge and inspiration to those who asked.
I am very grateful to Mary Hess of Bluebird Haven Iris Garden for many of the photos in this blog.

Talking About Arilbred Irises

By Maggie Asplet

Aril and Arilbred Iris are not something that you would expect to see a lot of in New Zealand.  We are very fortunate to have Bill Dijk and his wife Willy, living in Tauranga, North Island of New Zealand.

Bill is one of those very lucky people with green fingers.  Whatever he does, it just works and is very able to get the impossible to be possible in our climate, with a lot of hard work I must say.

This article was been written by Bill and he has given me permission to publish his take on Aril and Arilbred Irises.

I. acutiloba susp. lineolate growing in coarse material.

When we talk about the aril irises, two very different types of irises are grouped together under the term "aril".   These are the oncocyclus and regelia irises of the Near East.  Although they have beards, they are not classified with the other bearded irises because they are so different in their makeup. Aril irises have derived their name from a little cream aril or a collar-like fleshy appendage of their seed.

Aril seed cut - showing the embryo

The arils show dark signal spots below the beards with much veining and speckling, in an unbelievable range of colours. Unfortunately, the arils are difficult to grow in all but the warmest and driest regions of New Zealand. I will start off by showing a few true aril oncocyclus/regalia species.  

Close-up of spcekling on I.samariae x I. hermona) X I. kirkwoodiae

In this century, hybrids were produced from crossing the arils with the more common bearded irises. These are called "arilbreds" (ABs), and are usually very easy to grow and still display the spectacular features of the arils. The arilbreds are as diverse in colour and form as they are in their genetic makeup and the combinations of these features make this an exciting and challenging group of irises. Unlike their aril ancestors, arilbreds can be grown successfully in a wide range of climates. They give gardeners the opportunity to enjoy the beauty of aril-type flowers without having to provide the special environment the pure arils require. They usually bloom earlier than the TBs, with the SDBs and the IBs.

Culture of Aril and Arilbred Irises

Arils and arilbreds have a reputation for being difficult to grow. This is partly deserved, but also partly the result of misunderstanding. Unfortunately, the word aril is often used rather carelessly to refer to both arils and arilbreds.  These two types, however, are very different in their cultural requirements and their capacity to grow and thrive without special attention.

Growing the pure arils like the oncocyclus and regelia species successfully is a real challenge, and it’s often a question of understanding their cultural requirements and adjusts them accordingly. Not always easy with our sometimes excessive wet, and humid climate in the Bay of Plenty in New Zealand. A warm and dry climate like central Otago would be more suitable, somewhat similar to their native habitat.

I. paradoxa atrata. Note its small, dark purple falls.

Today's AB’s (arilbreds) are not hard to grow in most climates. A selection of arilbreds interspersed among a bearded iris planting will find that most of them will grow and flower without any special attention; however, some understanding of  their cultural preferences increases the odds, ensuring a greater rate of success.

Although pure arils are not widely grown, a quick review of their cultural requirements is valuable, because it casts some light on the needs of their arilbred descendants.

The aril irises are the oncocyclus and regelia species from the Middle East and hybrids having only aril irises in their ancestry. The oncocyclus in particular have always posed a challenge to gardeners living outside their native region. They go completely dormant in the summer, which leaves them susceptible to rot in rainy climates. Furthermore, they don’t apologise for being temperamental, sometimes thriving for four or five seasons and then simply dying for no obvious reason. Regelia’s are much more adaptable, but still prefer dry hot summers.

Many different methods have been used for growing/protecting oncocyclus irises, especially during their summer dormancy when they must be kept dry. In cool, wet climates, most growers make use of a shelter/cover/frame, greenhouse or any other form of protection. I build this structure (picture) which is open on both sides for extra ventilation, and elevated bed for extra drainage, that is covered with polycarbonate plastic cover to keep the rain out.  I prefer to leave it on all season in our New Zealand climate to control the often excessive rainfall, warm temps and high humidity at the wrong time during the summer, which could results in rotting of the rhizomes.

Raised protected bed for Arils

This way I do control the cultural requirements like watering when needed, air circulation, feeding, and spraying for any fungal or insect problems.

Knowing the cultural requirements of the pure arils, one can take a few basic steps to improve the rate of success with arilbreds. If you have a choice of planting locations, arilbreds should be placed where light and air circulation are best and where drainage is particularly good. Take steps to avoid or reduce excessive soil acidity. Don't make the mistake of coddling them in a sheltered corner for protection from winter cold; such locations may be shadier and damper during the summer months, and lead to more harm than good. It will not be necessary to dig them or protect them totally from rain during the summer, as most arilbreds do not go completely dormant and are not as vulnerable as the pure arils. However, it is still wise to practice very clean culture and keep an eye out for densely overgrown clumps that could benefit from division. Plan on dividing arilbreds every other year; you may even find a few benefits from annual division!

In general, arilbreds of less than half aril content (this includes most arilbred medians) are to be grown exactly like the bearded irises. Giving them special treatment is unnecessary and may even be harmful, if it causes you to depart from tried and true practices that your bearded irises thrive on.

Those of more than half aril content should receive some preferential treatment. They should not require the full-blown summer protection preparations demanded by the pure arils but will appreciate the best drained, most open, preferably slightly raised location your garden can provide.

Preparing the site

For all arils: first and foremost, sharp drainage is important and the prime requisite for successful culture. They are desert plants, so they need full sun for at least two-thirds of the day. If possible, some protection, or shelter, from rain and cold is helpful.

Washed brick sand, granite, course pumice, or other coarse material, can be worked into the soil to improve drainage. There should be a good supply of calcium. (Gypsum can be used to provide calcium and loosen heavy soil.) If the soil is acid, lime should be added. Planting the irises on hills or ridges can help the drainage in marginal soils. Many people plant arils in raised beds where sharp drainage can be "built in."

To summarise:
  •   full sun
  •   sharp drainage
  •   no water in summer for the pure aril irises while dormant.
Normally, the colours of aril blooms are extremely pure as well as clear. Alternatively, their blooms may even have wonderful blotches that contrast the colour of the flowers. When arils are hybridized with the standard bearded irises, the progenies retain a number of these attributes, while some other progenies may have new, but mesmerizing hues, patterns and streaks.

The falls of aril flowers have another typical characteristic. They may have veins and dotting or stippling in subdued or strong shades. These features may also appear in the standards of aril flowers. The dark, circular spots, also known as "signal", which appear at the end of the falls, are another typical trait of the flowers of oncocyclus irises, which distinguishes them from other iris flowers.

Iris mariae

Ideally, arilbred irises should be planted when they are just getting out of their hibernation or dormant period. You should avoid planting irises during the summer heat, as it is very stressful at this time of the year. Similarly, irises should not be planted during the late autumn just before the harsh winter months. In fact, the best time for planting irises is actually subject to the climatic conditions in your region.

Classification:  Nine Types of Arilbreds? Yes, Really

Although for awards purposes, the American Iris Society sorts all arilbreds into only two classes (less than 1/2 aril content and 1/2 or more aril content), the Aril Society International uses a more detailed system of categories that tracks not only the amount of aril content, but also the type of aril content (oncocyclus, regelia, or both).  

Close up of Iris paradoxa

An arilbred with only oncocyclus and bearded ancestry is an oncobred (OB). One with only regelia and bearded ancestry is a regeliabred (RB). If both oncocyclus and regelia ancestry are present, it is an oncogeliabred (OGB). This is by far the largest category.

If the arilbred has less than 1/2 aril content, it is marked with a "-" sign. If more than 1/2, with a "+" sign. If it has 1/2 aril content exactly, neither a "-" or "+" is used.

Aril seed as a rule are not easy to germinate, and there are several methods of germination:
Stratifying,  cutting and forced germination.  Aril iris seeds can be germinated with the following technique.

Forced germination" this is a technique that is often used for pure aril seeds to hasten germination. This method bypasses the need for any cold treatment.  The forced germination procedure involves cutting  with a scalpel or razor blade across the micropyle, across the end of the endosperm and embryo, in order to create an artificial rupturing of the micropylar barrier, which in natural situations germination could take a long time sometimes years to archive.  I use a special sharp grafting knife which I find personally more reliable and safer.

After soaking the seed for a few days in water (with some fungicide) to soften the seed, the aril and half the seed coat is removed, followed by cutting or slicing enough of the endosperm to expose the end of the embryo. I also borrow my wife’s art-craft 5X magnifying desk lamp with build-in lights for more close-up, hands free detail when slicing or cutting the seed.  

Most people do not do this with arilbreds, which germinate more easily.

Some people would try to stratify them and see what germinates first.  Sometimes temperature cycling is used as well. After all of that you could then try cutting or slicing them for faster germination. Be sure to sterilize the seeds before cutting them, especially for fungal protection when germinating seed in plastic bags or damp sterilized paper towels or whatever method you decide to use.

Points to recommend and remember:
1.   Hydration: Soak the seeds for up to a week in water with systemic fungicide.
2.   Remove the aril carefully (if it's an arilated species), cut the skin and slice a little layer to expose the embryo, which will be visible in the little hole of the endosperm.

Slicing aril seed

You need to be careful not to slice off too much of the embryo or you will negatively affect root formation and also risk damage to the embryo.
3. After cutting, put the seeds in damp perlite or vermiculate in little plastic bags.
I prefer damp sterilised kitchen paper towels for germination.
4.   When germination takes place in 2 or 3 weeks -

I prefer to very carefully transplant the little delicate seedlings directly into a 7cm X 9 cm peat pots, with a spray of systemic fungicide, outdoors in a cool, frost free place. Peat pots have the added advantage of no root disturbance when planted on into its permanent place or suitable container.
Having initial success with the germination, either forced or the traditional method is just the start of further necessary and ongoing special cultural treatment of the beautiful oncocyclus/regalia group.
After cutting/slicing I prefer germinating the seed in damp folded sterile kitchen towels, the moisture content when damp imho is just right for steady germination.  I then place the folded kitchen towels in an ice-cream container with the lid securely in place to prevent moisture loss, in a cool part of the nursery ( 10-15 C ). I inspect the seed at regular intervals for any sign of germination, with many seeds showing a radicle after 2-3 weeks in the damp kitchen towels.

I then proceed to very carefully prick out the sprouted seed, one at a time, in a 7cm X 9cm cm peat pot with 50/50 mixture of compost/fine pumice, water carefully to settle in the little seedling properly. Usually the seedlings ( 5-10 cm) will be ready for transplanting in its permanent place after 4-6 weeks. The very important advantages of the peat pots is no transplanting shock to the delicate seedlings, roots will easily penetrate the peat wall with no loss of growth. Don’t forget to spray the young seedlings with an appropriate fungicide at regular intervals for any possible fungal problems.

As is often the case with any specialist area of horticulture, complacency is the biggest killer and there is no substitute for constant observation, care and proper treatment.  The Oncocyclus and Regelia irises constitute an incredible group of plants that deserve nothing but the best.  The sight of just a single flower takes your breath away and a sight to behold.

To quickly summarise again :
    full sun.
    sharp drainage.
    dry for the pure aril irises, no water in summer while dormant.

These are some cultivation notes on how to grow the beautiful aril and arilbreds irises.

Photo Essay: Historic Varieties from 1926

By Mike Unser

A selection of irises I have grown that were introduced in the year 1926. In the United States Grace Sturtevant and Bertrand Farr were working in the east, EB Williamson and the Sass Brothers in the mid-west, and Mohr and Mitchell in California. England's own Arthur Bliss was thrilling European gardeners, as were Vilmorin, Millet et Fils and Cayeux in France and G&K in Germany. The new tetraploids from the decade before had unleashed much potential and possibility, and hybridizers were putting them to good use.

The World of Irises is the official blog of The American Iris Society. Now in its 99th year, The American Iris Society exists to promote all types of irises.

The Diversity of Color in Louisiana Irises - Yellow Irises

by Ron Killingsworth

In previous "blogs" we looked at other colors found in Louisiana irises.  This time we will continue our discussion of the diversity of color to be found in Louisiana irises by examining some examples of yellow Louisiana irises.  People see color in different ways, so you may not see all of these as being "yellow". To learn more about the official wildflower of the State of Louisiana, please visit the website for the Society for Louisiana Irises.

'Amber River' by Richard Sloan 1984
This is a cross between 'Clara Goula' (Charles Arny 1975), a famous white iris, and 'President Hedley' (Joseph Mertzweiller 1979), a dark yellow in the dropping form.

'Brazos Gold' (K. Strawn 1993)
Not a very good picture of a very pretty iris that is registered as "yellow-orange".  'President Hedley' is the pollen parent.

'Butterick' (Jeff Weeks 2010)
This is a recent iris but in the older open form.  Plenty of us still love the old open form.

'Candlelight Supper' (Kevin Vaughn 2001)
The registration picture looks a little lighter than this picture.  If the name is wrong, then it is still a very pretty yellow iris.

'Charjoy's Jewel' (Charles Arny 1977)
This iris is registered as "maize yellow self, yellow line signal, stands slightly fluted' but mentions nothing about the beautiful green style arms.  I really like this flower form.

'Dixie Deb' by Frank Chowning 1950
Folks, this is a golden oldie (there is an iris by that name!) that will still win you awards on the show tables.  Registered as "sulfur yellow self".

'Creole Canary' (Marvin Granger 1976
If you have access to the registration data bank, or a copy of the Society for Louisiana Irises checklist, look up the pod and pollen parents of this beauty.  It is one of the many cartwheel forms that Marvin hybridized.  Notice the petaloids on the ends of the style arms.  There is a difference between a "cartwheel" iris and a "double" but it is beyond my comprehension.  Notice the flower has all falls and no stands -- isn't that what a double is?

'Edna Claunch' by Harry Wolford 2004
This is an outstanding iris that won the Mary Swords DeBaillon Medal in 2014.  An interesting cross between 'Atchafalaya'  (Farron Campbell 1998), a dark red violet cartwheel form, and 'Dural White Butterfly' (John Taylor 1989), a famous white iris with green style arms.  Atchafalaya is the basin in south Louisiana and is pronounced ahg chaf a lie ya, kinda like you are sneezing.  To learn more about the Atchafalaya basin, check out this website.

'Enviable' (M. D. Faith 2002)
A really beautiful iris that is registered as "stands greyed translucent white and falls Indian yellow".  Some people when registering an iris use so few words to describe it, you would think they paid by the word.  M.D. did a great job of describing this one

'Green-Eyed Love' by A. Faggard 1980
Ok, so this one is not really all yellow but the falls are yellow!  I really like this iris.  The green style arms will catch your attention from across the garden.  I am not familiar with the pod and pollen parents.  It is similar to 'Easter Tide' (Charles Arny 1979) which I also grow.

'Gulf Moon Glow' by A. Faggard 1994
This beauty was registered and not introduced until I introduced it last year.  It was often entered in an iris show and had to be entered in the "seedling" section although it is a 1994 registration.  The American Iris Society (AIS) recently changed the rules to allow named seedlings to be entered in a show as seedling or into the registered portion of the show.  This is really a beautiful iris, another of my all time favorites.

'Ila Nunn' by Charles Arny 1967
A beautiful white self with a little ruffling on the petals.  It won the Mary Swords DeBaillon Award in 1972

'Ila Nunn'
This picture shows a new bloom along side an older bloom.

'Key Lime Pie' by Kevin Vaughn 2016
This beauty came out of the pod parent of 'Edna Claunch', discussed above.  It has a very complex pollen parent genealogy. You have to love the lime-green style arms and it has quite a bit of ruffling.  It is registered as the "flat cartwheel form" and notice it has signals on all the petals.

'Kraemer Yellow' by Kraemer 1943
This is an oldie but goodie.  It is a collected iris.giganticaerulea.  It is registered as "soft sulfur yellow".  A nice example of the open form of an older Louisiana iris.

'Laura Louise' by Joseph Mertzweiller 1990
I have thousands of this iris.  It grows like a "weed".  Very pretty yellow irises, registered as "yellow orange" and the picture in the registration shows it with more of an orange shade of yellow.  A great garden iris that for some reason never won any of the AIS awards.

'Lightening Quick' by Mary Dunn 1998
Registered as "medium yellow self" and a really nice iris.

'Rigolets' by Patrick O'Connor 2004
Once again this picture is not exactly like the one in the registration; however, the age of the bloom will certainly affect the color in the bloom.  A very pretty iris with the nice green style arms.

'Rokki Rockwell' by Dormon Haymon 1992
Registered as a medium yellow, this iris agrees with the time of registration, a more open form that newer yellow irises.  It won an Honorable Mention in 1995.

'Seminole Autumn' by Harry Wolford 2004
This iris is registered as "caramel yellow with fine rose veining" but there is a lot happening in this iris.  Another favorite iris and an eye catcher.

'Sunny Episode' by Henry Rowlan 1983
An older iris but a beauty.  The registration shows green style arms and that is certainly possible, this could be an older bloom and the style arms faded to pleasing yellow.

'Te Aroha' by Heather Pryor 1997
A very nice iris with lime green signals, quite ruffled, registered as "soft lemon white".

'Yeloponie' by W. B. MacMillan 1975

Registered as "light yellow self, green line crest" fails to even mention the beautiful green style arms. Another example of an open form older iris.  It won an Honorable Mention in 1979

As you can tell by the registration dates, we grow a lot of the older Louisiana irises, "historical irises".
