Species Irises: Back to Nature

by Tom Waters

I became interested in irises as teenager. After a year or so of growing tall bearded irises, I became more aware of the other types available, and of the special groups of enthusiasts who had gathered around each type. When I discovered that there was a group (SIGNA) just for “species iris”, I was baffled. In my biology classes at school, I had learned that the species was the basic category for classifying all life on earth. So didn’t all irises belong to some species or other? It didn’t make sense that there would be a special iris society just for species.

Beginning classes in school, naturally, emphasize simplified basic concepts at the expense of all the qualifications, complications, and exceptions that the real world has to offer. In school I learned that two individual animals or plants belong to the same species if they can breed and produce fertile offspring. But that’s not always the case, especially in the plant kingdom. Irises belonging to two different species can often cross and produce fertile offspring, and in fact this is how most of our named garden varieties of iris originated. Those named varieties (“cultivar” is the precise term) are almost all hybrids, with two (or more, usually) different species in their ancestry.

So now it started to make sense. People interested in “species irises” were interested in the original iris species that exist in nature, as opposed to the many garden cultivars that had been produced by hybridizing, crossing different species with one another.

I grow bearded and aril iris species, because I’m interested in hybridizing with them, and also because they come from parts of the world with climate similar to my own, so it seems a good fit. Many people grow other kinds of species: Siberians, Louisianas, and wild irises from North America, Europe, and Asia.

What is the appeal of species irises for gardeners? Obviously, botanists are scientifically interested in the original species, which are the product of natural evolution and occupy distinct ecological niches. For a gardener or iris hobbyist, this scientific curiosity can inspire interest in the wild species. But there are other lures as well. There are many species that have been used infrequently or not at all in hybridizing. If you take a fancy to these, you will necessarily be growing species. Some of us like the “wild look” as an alternative to the deliberately “altered” creations of human hybridizers. And some like the idea of growing the wild irises native to their own area.  For others, conversely, species from other parts of the world provide a connection with the plant life of distant lands and environments.

If you take an interest in species irises, you soon learn an important difference between species and hybrid cultivars. The hybrid cultivars are all propagated by division. Each plant is an identical replica of the original. Each one is really an individual organism, as distinct from all other irises as you or I are from all other people. But a species is not an individual. A species is an entire population of related individuals; it is like the whole of Homo sapiens from all the places humans live, with all their different characteristics and genetic heritage. So whereas I can “have” a particular cultivar, say ‘Dividing Line’, in my garden, I cannot “have” a species, such as Iris pumila. I can only have at most a few individual plants that belong to that species. They will all be different individuals, and all different from the great numbers of other  Iris pumila plants growing wild in Eastern Europe.
Species enthusiasts embrace this fact, and often strive to have a range of different plants representing each of the species they grow. This not only adds interest to the collection, but helps preserve some of the genetic diversity of the species in our gardens. Like many wild plants, irises are often threatened in their native environment by human activity and encroachment. The gardener who grows species contributes, in a small but potentially significant way, to their conservation and preservation.
For those of us interested in hybridizing, growing many different plants of the same species offers another benefit: genetic diversity.  If you trace the ancestry of our garden hybrids back far enough, you will find the same ancestors appearing over and over again. Despite all the range of color and form in the modern hybrids, they actually come from a rather inbred gene pool. Going back to the species expands the genetic base for our hybridizing efforts.

This brings me to a final observation. One can obtain species plants from commercial sources and others who grow them, including named cultivars in some cases (these are selected individuals of the species, not hybrids between different species). But it can be even more satisfying to raise species from seed. Many iris societies and rock garden societies have seed exchanges, where one can inexpensively obtain seed of many different iris species, including sometimes seed collected in the wild. There are also some commercial sources, mostly specialist plant collectors. When you raise irises from seed, you will naturally be “selecting” those plants with the genetic predisposition to do well in your own climate.


Growing species irises, particularly growing them from seed, provides a window onto the natural world that growing only hybrid cultivars cannot. There is a special pleasure that comes from raising these lovely wildflowers, knowing that you are enjoying (and helping preserve) some of the world’s beautiful and fascinating flora.

SIGNA Newsletter -- Winter 2014 Issue

By Andi Rivarola

The new Winter 2014 edition of SIGNA (the Species Iris Group of North America) is out, and here's an introduction and short recap. 

As we say in SIGNA, invite a friend to check what SIGNA is all about and/or to join the society. They won't regret it and neither would you. To join please visit our webpage, here.

In this issue, a fantastic article and introduction of two irises you may not have heard about: iris boissieri and iris serotina. Both are part of the iris Subgenus Xiphium that occur in the wild from the northwest of Morocco in North Africa, to as far east as the heel of Italy and also West into Spain and Portugal. 

From Russia, Nina Alexeeva introduces us to a new iris from the Kuril Islands, Iris lokiae. Find this exciting article in the section Irises from Russia.

You will also find wonderful list (including pictures) of recent introductions of SPEC and SPEC-X irises. A couple of white irises that caught my attention, and yes you may call me a white iris fool. 'Sushi' ( by Jill Copeland, R. 2013)  an I. pseudacorus X Ensata cross; and 'Precious Pearl' a crestata iris (by Barbara & David Schmieder, R. 2012); added them to my must-get list for next year.

I read with great delight the information on the article, History of the Iridarium, In Celebration of the 300th Anniversary of the Botanical Garden of Peter the Great in St. Petersburg, by
N. B. Аlexeeva, Curator. What an fantastic, detailed, historical account of this important organization. Loved this article and it made me aware of the amazing dedication and work that people do for the love of iris around the world.

There are so many more wonderful topics covered on this issue of the SIGNA Newsletter, we hope that you will consider becoming a member so you can read it in its entirety.

And, now for some more exciting news: The SIGNA Seed Exchange is now available. What is the Seed Exchange? For me, it's a wonderful way to grow species and other iris types in seed form to grow in my garden that otherwise I may not be able to obtain. The SIGNA Seed Exchange is a major benefit to SIGNA members. It is also the main fund raiser for SIGNA. The proceeds go toward the publication of the SIGNA Bulletin and help to sponsor collecting trips, special publications, and research grants. Although it is only available to SIGNA members, you may become a member when you order seeds. More information, here.

Don't forget to check our species iris database available to everyone on our website: http://signa.org/

Do you grow species irises, and what types do well in your area?

When Pacifica Iris Pods Are Ripe


Kathleen Sayce

Mid to late summer is exciting:  it's harvest time for Pacifica Iris pods. Some species irises shed seed by early July in my garden, including Iris tenax and I. innominata. These species often grow at high elevations in the wild, flower in May or June, and have ripe seed by mid July to early August. They waste no time cranking out the next generation. Other species take more time to ripen seeds, nine weeks instead of five to six weeks, including I. douglasiana. Pods often go through a color change as they ripen, from green to gold or yellow. Even when not opened, a yellow pod has mature seeds inside, ready to collect. 


Just a few weeks ago, seed pods were green. 




Iris pods are opening all over the garden by late July, when the mesh bags come into use. Here, all pods in this cluster have opened, the tips are spread on the upper two, and the bottom one has valves spread to show the seeds inside.

Mesh bags or nylon stockings are good devices to use to contain seeds and ensure that a gardener's work in crossing specific parents isn’t lost at the seed collection step. Saving even a few seeds from a choice cross can be important in a hybridizing program. 

I cut the stems and collect the pods, still in their mesh bags, to dry before taking out the seeds. The stems can be tied together with a wire tie or string, hung in a dry shady place, out of the sun and away from direct heat––just as you would dry herbs or flowers, or put into paper bags in a warm dry spot. After a few days, any pods that can open, have done so, and the seeds are ready to clean and package. 


A basket of treasure:  Ripe pods in paper bags, ready to dry indoors. 

Normally the valves separate from the pods, and the seeds break off and scatter. Occasionally pods stay closed or only partially open. Either the tip will not separate, or the sutures along the edges do not open.  When this happens, I use a knife or razor blade in a holder to cut the tip off, or cut along a suture line, being very careful to keep my fingers intact, and to not cut into seeds. Then I gently peel out the seeds.

Seeds go into a bowl. Use a large bowl that you can swirl seeds around in. This lets you blow or toss seeds outside to separate seeds from chaff and pod fragments. I also use a sieve to shake out fine bits if the pods are dirty. I clean the seeds and remove all non-seed bits and pieces, insects, et cetera. Separating seeds from chaff is a very old process. Humans have been doing this for thousands of years. And it’s fun! 

After the seeds are clean, I put them in a clean bag (mesh or paper), to continue air drying. The label moves with them. I save seeds for seed exchanges, such as Society for Pacific Coast Native Iris, and Species Iris Group of North America.  

I learned the hard way to not put fresh seeds into glassine or plastic bags––they mold. The mold doesn’t kill the seeds, it’s just in the seed coats, but it looks terrible, and when it’s really bad, all the seeds are encased in a dense whitish mold into one solid lump. Ugh!  If there's too much mold I scrub the seeds with a plastic scrubby to clean them, then rinse and re-dry the seeds. 

Drying seeds, in a row of paper bags. This takes patience, and at least ten days!

Let the seeds dry thoroughly before packaging each seed lot. I’m not naturally a patient person, so this is hard. Wait ten days, at a minimum. More is better. Only when the seeds have dried indoors, in a clean mesh bag, and I have let the days slip past, do I then put the seeds into an envelope, label it, and set it aside to send to a seed exchange. I also share seeds out to gardening friends, and this is when those seeds are mailed. 

Labels need to include what, when, where, and any details of the plant or flower that are important. List:  Pod parent, pollen parent if known, the flower color on the pod parent if it’s a species or unregistered new flower, likewise any characteristics of the pollen parent that were important to note, or bee-pollinated, if open pollination was used. If you use crossing codes to track garden crosses, write down those codes too. This helps you and others track the parentage of your seeds. 

Another task is to take all the used mesh bags, wash them in warm soapy water, rinse, dry, and then freeze them for at least two weeks. Why freeze the bags? If any invertebrate eggs are in the bags, this will kill them. Washing, drying and freezing helps ensure that the bags are clean, and ready to use again next year.  

Do you grow PCIs, and do you save seeds to give to other gardeners?

SIGNA Newsletter Winter Issue

By Andi Rivarola

Here's a recap of SIGNA's Newsletter Winter Edition

As you can see from its cover below, Juno irises are featured in detail, and the article crafted by Panayoti Kelaidis from Colorado, is as complete as they come. With well over fifty species in its section, Junos come in all sorts of colors and tones, and with an average height of between 6 and 12 inches. I added Junos to the list of irises I want to grow and learn about. If you have not heard about Juno irises, where they can grow successfully, and most importantly how to grow them, then I hope you get to read this article.

SIGNA (Species Iris Group of North America) Newsletter

There's also a wonderful update about Iris ruthenica, on the article called Irises from Russia, by Nina Alexeeva. This beautiful medium size iris can be found in nature in Central Europe and Central Asia all the way to Mongolia and China. Despite its large habitat many gardeners in these areas are still learning about the potential of this violaceous beauty. A wonderful read.

With humor as a sizable and necessary part of the irisarian's experience, our own World of Irises blogger, Griff Crump gives us a great opportunity to laugh about some of the tricky and interesting iris names we may encounter. The article is called: "Humor -- Those Puzzling Iris Names."

Dennis Kramb gives a detailed report on the Siberian and Species iris Convention held in 2013 that you won't want to miss.


A favorite iris variety that I have yet to grow is covered in detailed on an article with fantastic images to enjoy. I'm talking about beautiful irises dichotoma and domestica, and their child named Iris x norrisii (ex-pardancanda). The article is "Identity Crisis" by another of our wonderful World of Irises blogger, experienced iris grower -- and gardener extraordinaire -- Jim Murrain.

Lastly, I know SIGNA leaders would want me to mention that the SEED EXCHANGE is ready and open to receive your orders. If you don't know about the seed exchange, may I direct your attention to SIGNA's website: http://www.signa.org where you can find more information about obtaining seeds of iris species and other hybrids, and also to browse through a list of iris types available. Although you have to be a SIGNA member to order seeds, you can become a member online at the same time as you order seeds.

SIGNA newsletters are a pleasure to read, and I hope you too find them a great learning tool while immersing yourself in the world of iris species.

SIGNA Seed Exchange Siberians

by Jim Murrain


Kansas City, Missouri gardener Rick Davis had grown Bearded Irises almost exclusively for decades. Shortly after he joined the Greater Kansas City Iris Society he moved to a larger lot in Independence, Missouri. If you live in the Kansas City area and grow Iris you will eventually be asked to help with the Species Iris Group of North America Seed Exchange. 


Rick was asked to help count and package seeds a few years ago. This was his first serious exposure to beardless irises. The second year he helped he joined SIGNA and purchased a variety of seeds. At the end of the shipping season we had a sale on left overs and he purchased a few more.


Rick planted the seeds in tin cans and old flower pots and left them outdoors to let mother nature care for them. As Spring arrived he watered as needed and got good germination on most kinds of irises. Some didn't come up until the following year though.


He had especially good germination on siberian Iris cultivars. They looked like tufts of grass in the pots. When weather permitted he lined them out in a new garden area.


Unlike myself Rick is a keen gardener and kept the weeds at bay and watered the seedlings during dry spells. The photos here are three years old plants grown from those seeds.


While Rick had good flowering on many types of iris I was there at peak siberian season so can share these with you. You can see modern forms and species type like the one below.


I would call this a pink bi-tone.


A near double or six fall seedling.


I especially loved this row where the stalks were over four feet tall.


A soft yellow.


A good 'red' siberian.


A very cute species type flower in palest lavender with darker veins.


Many shades of Iris.


Soft pink with butter yellow styles and golden signals.


Almost a watercolor effect on this seedling.


Dick Davis discussing the garden with a member of the Greater Kansas City Iris Society


Unfortunately last spring was the last full year for Rick's garden. He dug and donated all of his bearded irises to a sale last summer. If he is able to keep the property into spring 2014 we will be selecting and digging beardless irises to move to member gardens. This is rental property and is listed for sale.

It was fun to see the amazing diversity that growing irises from a wide range of sources gave his garden in only a few years and at a minimal cost in plants.

The SIGNA Seed Exchange is arriving in early January and is a great way to add color and variety to your garden with the excitement of being first person to see a new seedling in flower.

'Woolong' wins 2013 Founders of SIGNA Medal



By Jim Murrain


The 2013 Founders of SIGNA Medal is awarded to...
'Woolong' collected and named by James Waddick of Missouri.


Here's a full description of this beautiful Iris via the Iris Wiki:


'Woolong' (James Waddick, R. 2001). SPEC (tectorum), height 10" (25 cm), Mid bloom season. Blue violet, falls with darker spots and flecks, white signal and crest; style arms paler blue violet. Collected in wild, Woolong Valley, Sichuan, China, 1989. Iris City 2002. HM 2006, Award of Merit 2010. 

The photos are of the original collection site and taken by James Waddick.


This is Jim's third win of this prestigious medal.
For information about this award go here.
Following is a brief description of Waddick's finding of Iris tectorum 'Woolong'.


In the summer of 1988, Jim Waddick, Bob Pries and Jim Murrain all thought that some one should go to China and collect some new wild species plants to expand the gene pool. 

It fell on Jim Waddick to go in May 1989, and then the Tiananmein freedom demonstrations started. Straying to the far reaches of the country, Jim and his guides traveled to the famed Woolong Valley of Sichuan Province, best known for its Giant Panda Reserve. 

While driving the only road through this narrow valley, Jim saw some vaguely familiar (but not quite) leaves hanging over the road, and they stopped. There was a huge patch of the crested Iris tectorum, but extending 20 or 30 feet across and looking especially big and husky.

 It all seemed to be a single giant plant connected by years of spreading rhizomes. A few fans were collected and survived in cultivation. It did prove to be an especially vigorous form of this familiar iris and was then named and introduced.

Please visit  the: Species Iris Group of North America website to learn more about growing and identifying the diverse species of Iris.

9 Out Of 10 Gardeners Recommend Crests

by Jim Murrain


The best known of the Crested Iris is Iris tectorum. It is often referred to as the 'Japanese Roof Iris'. Of course we now know that it is not native to Japan nor does it grow on roofs unless forced to do so. It is one of the most common of the irises native to China. 


 It is very easily grown from seed or, thanks to its fairly large rhizomes, from divisions. Iris tectorum seeds have been available via the SIGNA (Species Iris Group of North America) Seed Exchange every year since I joined almost 25 years ago. It remains a very popular iris.


When grown from seed and a goodly number planted in your garden you can admire the many different shades of lavender and even white this iris manifests.


However we must take note of the crests! They can vary a lot on each seedling and somewhat on each fall! It can look almost like a simple beard or large jagged ridge to wild shapes that remind me of corals seen  under water. 



The amount of spotting or water marks on Iris tectorum can also be highly variable. It can have clear clean colors to heavily marked petals. The marks show predominantly on the falls but can manifest on the standards also. 



This is one Iris where you can say "I have the blue, now I want the white". But the fun of growing a number from seed is to see the natural variations that can occur.


Even after being grown world wide for many years there are only a few named selections available, and they were primarily chosen for larger flowers or the amount of spotting. None of the odd forms have been chosen. I'm sure some of you would enjoy a monstrous form as seen here:


Iris tectorum has a huge range in its native land and can be grown in most places where people live. It will need a protected location in very cold climes and may benefit from growing in a pot under shade in warmer areas to help keep it cool when dormant. It is a fun iris in so many ways, and so easy even a child can grow it.

Most of the photos were taken in the garden of Rick Davis of Independence, Missouri and grown from SIGNA seed.
