The Iris at the End of the Rainbow: the Favorites of Ginny Spoon


By Renee Fraser


Traditionally, men arrive for a first date with flowers. Don Spoon brought Ginny just the pollen! And so at their first dinner date in 1993, Ginny made her first iris cross, 'Zurich' X 'Chaste White', using pollen from Don's garden. The match produced offspring:  Ginny's first iris introduction, 'Autumn Ivory'.
Does it get any more romantic than that?

Don and Ginny Spoon are the owners of Winterberry Gardens in Cross Junction, Virginia. Their gardens are in USDA zone 6, 1100 feet above sea level. The main problem in their climate is the extreme temperature shifts. Spring temperatures might go from the mid 80's in the daytime to 25 at night! Those of you gardening under these conditions know that this can pose challenges for growing irises, because they may begin to bloom and still be vulnerable to frost.

Don started hybridizing as a youngster, over 60 years ago, along with his mother, Lilla Spoon, who was president of the Charlotte, North Carolina Iris Society at the time. Don majored in biology, earning his Ph.D. and taught at Georgetown University in Washington, D.C. for over 22 years. He established a lovely garden there, which is still maintained by the staff at Georgetown. Don also discovered a previously unknown organism and published a scientific paper and got to name it [Euhyperamoeba biospherica]. Ginny earned a degree in horticulture, and she says "so of course, the biologist and the horticulturalist are always arguing over who is right about what to do in the garden, but we manage to do it without too much bloodshed."

Don and Ginny worked at the Biosphere 2 in Arizona when they were first married. He helped design the ocean and was in charge of it for two years. Ginny went along for the ride, but ended up taking care of the Intensive Agricultural Biome for three months so the manager could visit his family in Nepal. They planted quite a few irises around the Biosphere 2, where they still grow today.

One of Ginny's favorite introductions is Don's 'Little John'. Ginny says "Don took me out to a large planting of his seedlings in Maryland where I first saw 'Little John' in bloom. Of course it was just a seedling then. I wanted it but we had no tools and the ground was dry and hard as cement. Don was ready to leave but I had to have a piece so I took a rock and managed to chip out a rhizome. I planted it and the next year it was in bloom with 11 buds. Don got his shovel right away and we traveled the three hours to dig out the rest of it.

'Little John' 1996 Owens Rebert garden
'Little John' was not named for the character in Robin Hood as many people have thought, but for a young man who helped me in my garden who was a John Junior, but his dad called him "Little John." Sadly, he died very young from leukemia, and I asked Don if I could name my favorite iris for him. 'Little John' is a cross of 'Damsel' by 'Queen Dorothy' and since it is half rebloomer it also has produced rebloomers for us, including broken colors. I have seen it growing very well in Colorado, Oklahoma, Texas and Maryland. I think the best planting was at the garden of Owens Rebert."



'Orchid Dove' 2007 (Lady of Leoness sibling X Uncle Charlie)
 When a dreamy orchid-colored seedling bloomed, Don kept asking Ginny if she could see the dove-blue color in the crests. Hence the name 'Orchid Dove'. It has been reported to grow well wherever they have sent it. At the National Convention in Wisconsin it got the most popular votes for a tall bearded iris out of region.

'My Ginny' 2000 (Sweet Musette x Femme Fatale) X (Winifred Ross x My Katie)
Don was waiting to name an iris after his love, and when the first flower on this seedling opened, his exclamation of joy and surprise was "My Ginny!" Both Don and Ginny love the 'Emma Cook' color pattern.  'My Ginny' won the popular vote at the International Competition in Florence, Italy for a commercial variety and the Franklin Cook Cup at the 2003 National AIS Convention. It grows well all over the U.S.


'Daughter of Stars' 2001 (Clarence X Mindreader)

'Daughter of Stars' is another of Don's irises beloved by Ginny. They named it after the local Native American legend about the Shenandoah River, which says the river is so deep and dark that it gave birth to the stars. This iris won the Wister Medal 2007. It grows well all over the country and reblooms in zones 6 through 9.


That takes care of Ginny's favorites hybridized by Don, but what of her own efforts?

'Selah Christine' 2012 (Sariel X Orchid Dove)
Of her own introductions, a great favorite is 'Selah Christine', which is named after Ginny's granddaughter. It has been awarded an Exhibition Certificate (EC) which is the only award an iris can get that is not a garden award, and a High Commendation (HC) for a seedling iris. She has high hopes that it will also do well in most areas.



'Zippo' 2011
Another is 'Zippo', a nearly black SDB (Standard Dwarf Bearded) iris with large pure white beards, is named for Ginny's daughter-in-law's cat, which is black with white paws.



'Velvet Elvis' 2012 ((Cerise Boy x Candy Corn sibling) X self)
A wide, velvety red iris with showy orange beards inspired the name 'Velvet Elvis'. This SDB won an EC as a seedling.



'Autumn Rose' 2008 (Diamond Blush X Chatter)
The striking 'Autumn Rose' reblooms in the autumn.  Ginny crossed Don's beautiful pink rebloomer 'Diamond Blush' and Ghio's dark pink plicata, 'Chatter' (which rebloomed once for them) and got a nice zone 6 rebloomer. Don had told Ginny that if you cross a solid color with a plicata it would intensify the color, and indeed it did. It is a very intense rose pink that stands out in the garden.


When Don and Ginny met at the C&P Iris Society, they each had a large collection of rebloomers. They continue working to produce irises that are multiple rebloomers with modern form, vigor, and exceptional coloration.  I grow two of their irises in Southern California.  MY favorite is 'Plum Pretty Whiskers' which has that gorgeous orchid color of many of their irises.  It is not listed as a rebloomer, but it reblooms in my garden. 

'Plum Pretty Whiskers'
I also recently planted what may be their most famous iris, 'Daughter of Stars', even though I had to create a place in my garden for it.  I couldn't help myself!

Do you grow any Spoon irises?  Do they bloom in your zone?  And are there any irises that you would love to see in a reblooming version?  Let us know here in the comments section.

Hottest New Louisiana Iris Seedlings

By Ron Killingsworth


When you take pollen from one iris and put it on another iris, you are said to be "hybridizing" an iris or "crossing" an iris.  The pollen is taken from the "pollen parent" and the pollen is placed on the "pod parent".  You might consider the pollen parent the father and the pod parent the mother.  The pod parent is the bloom that is going to be pollinated and will produce the seed pod containing the seeds of the new "cross".  There are a lot of people out there dabbing pollen on irises!  Each cross will produce seeds, if you are lucky, and the seeds, when germinated, will produce "seedlings".  Seedlings are new irises produced by your hybridizing efforts.  The Louisiana (LA) iris seed pods are harvested in about July or August in Louisiana and the seeds are potted up and marked with the identifying data of the cross.  With luck the seeds will germinate in the fall and continue to grow through the first bloom season and on through another year, finally blooming in the second year.  So it takes a couple of years to find out what your cross produced.

The new irises called seedlings are identified by a seedling number until such time as the hybridizer decides the iris is worthy of registration and eventual introduction.  Registration is accomplished through the American Iris Society.  A seedling continues to be classified as a seedling, even after it is named and registered, until it is introduced by offering it for sale and publicizing its availability through a commercial grower, or through your own garden.

Here are some lovely 2011 seedlings from  LA iris hybridizers:

As you can see, Louisiana irises come in just about every color under the sun.  Now that you are all excited about making some new irises, take at look at the web site of the Society for Louisiana Irises and learn more about hybridizing irises.  Give it a try.  You might just produce the next "Dykes" award winner!

Siberians that the World Overlooked

By Bob Hollingworth

'White Amber'
For any iris, winning awards is a matter of both worthiness and luck. Luck is always an element in the recognition equation:  an iris might put on a particularly impressive display at an iris convention where many judges see it. Or it may put on a great show of bloom, but a week before the convention visit. It may have been planted on a rock, or at the corner of a sunless bed that missed water and fertilizer. In other cases, a worthy iris may never get to the convention for various reasons, perhaps there is not enough stock, for instance. Over the many years that we have sent Siberians to conventions we have seen all these things happen. We have also been lucky when an eye-catching plant showed itself off like a fashion model just as the visitors came. So here I would like to start a series that recognizes fine Siberians, that for one reason or another, never seem to have received the recognition they (to me at least) deserve.  

'White Amber' (Photo by Brock Heilman)
I don’t understand why Marty Schafer and Jan Sack’s 'White Amber', introduced in 2001, has never received any AIS award; not even an Honorable Mention. Maybe they have so many good introductions that some just get overlooked in the crowd, but 'White Amber' for me is one of their finest.  It grows very well for us, blooms early and reliably produces masses of bloom held so that the clump effect is near-perfect. The colors of the flower are novel and satisfying.

It comes from a complex background involving 'Reprise', 'Mad Magenta, 'Isabelle', 'Silver Illusion' and 'Snow Prince'. Surely 'Snow Prince' must have had a significant role because the flowers are relatively small, though compact and nicely ruffled, and the plant generally has a “sibirica” appearance.  Maybe Isabelle helps with the yellow base. The color is perfectly captured by the name – a smooth, warm, milky amber color on the falls that comes from combining yellow and light lavender–pink and which intensifies towards the hafts. The standards are near white and the style arms are mainly yellow. It is certainly in the top dozen Siberians I would take if banished to that proverbial desert island.




Another in the characteristic of a great iris is that it is a fine parent. Again it seems 'White Amber' has been overlooked. The AIS Iris Register lists no named progeny. That is until this year when we introduced an iris called 'Lemon Mousse' which is from 'White Amber' x 'See Ya Later' (Hollingworth, 2006). That cross gave irises in a variety of colors and patterns with several being good enough to take to the next stage for consideration.
I used 'White Amber' because it had such pleasing growth and flowering habits and because I was interested in the combination of yellow and lavender or red shades in Siberians. 'See Ya Later' comes from that kind of background too. So it’s rather ironic that 'Lemon Mousse' has no trace of red. It opens light yellow and fades to pure white with a yellow heart. The flowers are larger than 'White Amber', but produced in the same profusion. Another iris in this cross (05R1B15) did show the lavender and yellow combination along with striking yellow style arms. This too would have been introduced if not for a bunch of white grubs that ate the roots off in a dry summer several years ago. That’s when we discovered that European Chafer grub populations were rapidly on the rise here in Michigan.

10J13B3  (No. 1)

10J13B7  (No. 2)

The results of this cross were so pleasing that I decided to do another similar one using 'White Amber' and our 'Gem Quality' (2008), a seedling from 'See Ya Later' x the yellow 'Smiley Face'. And again the results have been fascinating – tremendously varied and some quite surprising, with all flowering vigorously. Here are three of them  The first, 10J13B3, in which red-violet is combined with yellow to give orangey shades (the photo is less than ideal I’m sorry to say), and the second one (10J13B7) combining blue-purple and yellow to give some brown tones on the style arms and falls, may not be so unexpected, but where did the third (and most interesting) one come from? 

10J13A1 (No. 3)
Reddish on top and blue below, 10J13A1  probably gets its bright gold signal from 'Gem Quality'. I expect that one or two of these may eventually be introduced if they continue to grow well and our control measures keep the grubs at bay.

So to me 'White Amber' is an under-appreciated gem. I still vote it for an HM every year though I suppose its time is now past. Irises are never technically out of the running for an HM, but not being listed on the ballot now is a killer. It seems that some irises just can’t get lucky, but if you want to add a fine Siberian to your collection, do keep it in mind.

This, That, and a Few Other Things

By Brad Kasperek

Greetings from the top of Utah - I'm b-a-a-a-a-ack!  I've heard lots of interesting rumors about what happened to Kathie and I, but reality wasn't quite as interesting. Neither of us died, were in a serious accident or were at death's door, but we both had health issues that brought abrupt changes to our quality of life. Physical recoveries and mental adjustments to the realities of our aging took time. Anyway, we plan on re-opening Zebra Gardens this year and even introducing our first two spurias.  Nothing too exciting, but I believe one of them will offer something new in color combinations. I've had to reevaluate and reduce my previous iris hybridizing goals to decide where my major interests now lie.  The result was a decision to make spurias my primary focus for the future.  Don't everyone groan at once!

Spuria Iris 'Ode to a Toad'

In the Winter 2011 issue Jim Hedgecock wisely encouraged spuria hybridizers to acquire a selection of spuria species irises and to incorporate them into their hybridizing programs. The hope for outcome would be an increase in colors and patterns within the hybridized spuria genotype. This is great advice and new hybridizers should make it one of their goals to do some of this hybridizing. However, it appears to me that the pattern diversity within the I. Spuria species is much more limited than in bearded irises. Thus we should also continue working to fully identify the recessive characteristics of the existing genotype (color, pattern, size, ruffles, frills, etc.). This is what happened and continues to happen in the hybridizing of bearded iris. Look at the variety there!

Spuria Iris 'Ibex Ibis'

Once again for at least the 1000th time I relearned the hard way that if I think I know what I'm doing - I probably don't. These delusions exist only because I wasn't smart enough to ask the right questions when I should have.  After my experience with hybridizing bearded irises I assumed hybridizing spurias would be similar -wrong!  It seems that every technique or process I used with bearded irises was just far enough off the mark to impede my success with spurias in both producing seed and getting it to germinate. Seed germination has been the bane of my spuria hybridizing and I've tried everything I could think of to improve my results, but I always planted the seeds in POTS. Last year, Iris, the goddess of the rainbow must have smiled on my hybridizing efforts because we harvested almost 21,000 spuria seeds which was a huge increase over all other years. So I quickly created a convoluted plan to test several new methods of improving germination and producing seedlings large enough to transplant by mid-May. The crosses with the highest number of seeds were split into three groups: green seed to freeze, green seed to chill and dried seed to soak at the end of December. On the 2nd and 3rd of this January we potted these seeds up in 77 - 2 gal pots and stored them in my bedroom to await their later transfer to the greenhouse. I'll let you know the results in my next column. They should be good for a laugh at least.


So with this work out of the way I finally decided it might be a good idea to check with Dave Niswonger to see if he could provide any help with my germination problems. Dave told me that the most important factor affecting spuria seed germination was how many soil particles were in direct contact with the seed. Thus he plants his in a seed bed made of loamy soil without any added peat moss or other organic material and gets around 75% germination. Incorporating organic material would reduce germination by reducing the seed to soil contact.  Additionally, he said to NEVER POT the seeds up because potting mixes have very poor soil to seed contact!  Now why didn't I ask him for this advice six years ago!!!  Or even six months ago!  As "they" say - the only stupid question is one not asked.

Spuria Iris Seedling 5SP-11A
My early years of hybridizing tales of woe will become an article at a later date after I have some confidence that I finally know how to hybridize spurias in northern Utah. One thing that I'm certain of is that geographical location, temperature zone, length of growing season and the amount, form and timing of precipitation makes an enormous difference in the culture of spurias whether gardening or hybridizing.  It's my impression that this sort of information isn't adequately documented or mentioned in articles or on our website.  Do you believe this information would be valuable if someone (ah! that elusive someone) would try to compile it?  Please contact me at zebrairis@gmail.com if you think this is a worthwhile project.

Have a wonderful bloom season!

Brad Kasperek at the 2006 AIS National Convention

Editor's Note: It is with great honor and pleasure that with this article we bring you a new area of exploration to World of Irises - the Blog of The American Iris Society -- Guest Bloggers. Brad Kasperek is the first, and there's a reason for it. He is a hero of mine, for having had the courage to "boldly go" in pursuit of his fascination with Broken Color irises. I mean, the name of his business says it all, "Zebra Gardens - Irises of a Different Stripe."

I can never forget how surprised I was to hear Jim Hedgecock say at one of his presentations that with only about 800-Spuria iris varieties registered, the field of spuria iris hybridizing is quite open, and the opportunities endless. So, I feel that Brad's work will bring new life to the world of Spurias.

I'm very glad Brad explains about his and Kathie's health issues at the beginning of this article because as someone who followed their work closely, I was worried. So, Brad and Kathie, glad you're back on your feet and in the garden because the result will be, as we all know, beautiful irises. Welcome back!

I hope we can get to hear more from Brad in the future. I will follow his steps into spuria iris hybridizing adventures with great interest.

A similar version of this article first appeared in the Winter 2012 Edition of Spuria Iris News, the newsletter of the Spuria Iris Society.

Brad was kind enough to provide me the descriptions of the two newly introduced spurias:

'Ibex Ibis' (Kasperek 2012), SPU, 45", M. Light medium lavender standards, stylearms and rim around fall with a bright yellow fall center darkening to gold at the arm crest, 5 to 6 buds.

'Ode to a Toad' (Kasperek 2012), SPU, 38", M. Rich, red-brown maroon standards and mottled purple & brown style arms. Rich, orange-gold falls rimmed and modestly veined in smoky maroon, 4 to 5 buds.

After the Meltdown


Rebloomers tend to be among the first tall bearded irises to bloom in the spring, and they often color the garden for a week before the oncers begin blooming.  In early April, 'Tara's Choice' and several other rebloomers were looking great.  Unfortunately, I knew it was way too early for them to be safe in my Kentucky, zone 6, garden.  

'Tara's Choice' (Wilkerson 2004)



As I finished my last AIS blog entry, the garden was hit by a heavy frost extending over three consecutive nights.  Many of my seedlings were in full bloom and I'd begun making crosses for the 2012 year.  They turned out to be busy work.  The immediate concern was damage.  What was damaged and how bad was it?  

Frost damaged stalk
It was bad.  All stalks were cut down by the frosts.  Most of the bloom was gone for the season, but a small number of irises put up new stalks.  Some of the newer seedlings managed to open a bloom here and there.  Although nothing could be evaluated due to damaged blooms, it was nice to see the colors.  Who would have expected 'Born to Exceed' X 'Renown' (blue bi-tone and white) to produce a yellow seedling?  I'd hoped to expand my photo collection, but unfortunately, I was not able to take many pictures. This blog will be handicapped or limited to existing photos until I have another good bloom season.

There were no pods in the tall bearded section for 2012.  About twenty crosses had been made when the frost hit and none survived.  Another ten crosses were made post frost and none of these took. Recently germinated seedlings were frost bit but few were killed, fortunately.

Since the spring bloom was three weeks early, so it should be no surprise that rebloom also started earlier this year.  'Pinkness' (Byers 89) tried to spring bloom, was damaged. and it was the first introduced iris to put up a new stalk, followed by 'Gate of Heaven' (Zurbrigg 2004) and 'Artistic Showoff' (Wilkerson 2011.)  This is early for my garden, but there are reports of early rebloom in many parts of the US of A.

'Pinkness' (Byers 1989)

'Gate of Heaven' (Zurbrigg 2004) (Yum!)

'Artistic Showoff' (Wilkerson 2011)


Even before these three irises bloomed, two of my summer blooming seedlings gave a show.  Both 2025-02Re and 2130-01Re have bloomed in July but started rebloom in June this year. Both have been used in breeding. 
2025-02Re Wilkerson seedling (Total Recall x 1625-01Re (Star Gate x  (Violet Returns x Breakers) 

2131-01Re Wilkerson seedling (Again & Again X Echo Location) 
I also have a couple of seedlings with stalks showing color.  They won't open by June 25, but I'll give you a little peek at what I'll see in a few days!  2102-04Re has been a favored seedling since it was transplanted from the seedling pot back in the fall of 2007.  At that point, I was impressed with its great root system, and I fully expected it to rebloom.  My enthusiasm gradually diminished as I watched it set bloom stalks each spring, right after bloom season, and waited (impatiently) for signs of a fall stalk.  Each year it sat and waited for spring to send up the stalks.  In 2010 I moved a piece of it to the new beds.  The clump opened three stalks post-frost season this spring.  Last week I was thrilled when I finally spotted a rebloom stalk.  I was shocked because I'd given up.  More about this one in a later blog.  It has great breeding potential.


2102-04Re Wilkerson seedling (Star Gate x (Bridge In Time x (Feed Back x Titan's Glory) X Arctic Fox

1907-10Re Wilkerson seedling (Blatant X All Revved Up) 
1907-10Re bloomed all summer in 2011, had spring stalks, and it has another stalk ready to show color now.  This shows potential for a good 2012 rebloom season.  I hope to have a lot to report in August.  At least I can dream.

Much of the country had an early bloom season in the spring.  Did any of your irises get hit by frost?  Have any of your reblooming irises sent up new stalks already this summer?
