Dry Summers, Summer Water and Pacifica Iris

Kathleen Sayce

Pacifica Iris, or PCI, thrive in a mediterranean climate––that’s a small ‘m’ for the climate, not the geographic area. This climate type has a wet fall-winter-spring period, with rain starting in early fall to winter, and ending in late winter to late spring, depending on latitude. In the Pacific Northwest, cool wet weather can last from six to ten months, and very dry weather (no measurable precipitation) two to six months. Most years, the August-September period is very dry. Going south on the West Coast, the wet season shrinks until in southern California, it lasts a few weeks in midwinter, and the dry season lasts most of the year. 

Iris chrysophylla x I. douglasiana, a large leaved, branched flowered form that flowers in June. 

It’s August now, and that means the West Coast is well into the annual dry season, from northern Baja California, Mexico to somewhere along the British Columbia coast. My garden is dry, and I’ve started supplemental water to some plants, but my PCI do not get supplemental water. The last of the PCI are ripening seeds, most have already open seed pods, and they are toughing out the dry season in a warm dormancy. Roots are not growing. These irises wait out the dry weather.

Seed pods from the same plant as above, 2 months later. 

I could clean up plants at this time, but I have learned that if the dry season is prolonged, then PCI will abandon more leaves, and I’ll have to take those leaves off later. So I limit my cleanup to removing vigorous weeds, dead plants, and any plants I want to remove from a particular spot. There’s no replanting this time of year. Plants that are dug out now will not reestablish if replanted. If I were watering regularly, I might be able to transplant in a few weeks. 

On watering PCI in summer, opinions are mixed. Some say no water at all. Many  nursery growers have found that PCI are fine with regular summer watering. As Secretary for the Society for Pacific Coast Native Iris, I’ve been offered many opinions from members all over the world on this subject, and have concluded that PCI do not like hot, alkaline water. Cool, neutral to acidic water is fine. I prefer not to drag hoses or sprinklers, so I do not water them, though my plants would probably be bigger and have more flowers if I did supply water all summer.

Late summer is a curious time in the garden:  Flowers are still abundant on many perennial and annual plants, which will keep flowering with supplemental water into fall. Butterflies make the rounds on warm days, feeding on those flowers. The end of second flight of Anise Swallowtails is still underway. Margined White butterflies are on their fourth or fifth adult generation for the year. Soon, the occasional south-migrating Monarch butterfly may pass through. Even these plants are shedding leaves, setting seed, getting ready for summer’s end. Meanwhile, fall flowering bulbs and perennials are starting to show buds and first flowers. 

The clear signal that fall is coming is birds migrating south. I live on a large estuary, Willapa Bay, where tens of thousands of shorebirds, ducks and other waterfowl fly through each fall. Shorebird numbers are picking up from week to week. Bald Eagles fledged their chicks; the adults will leave by September for inland rivers, to fish for fall migrating salmon. I hear the fledgling eagles call for their parents by mid August, looking for those formerly attentive parents.

New visitors, two Indian peacocks, check out the flower beds. The turquoise, silver and blue eyes in the tail feathers would make a striking PCI flower.  

 This week, there was a new bird species in the yard. It’s not migratory, and yes, it is introduced. Two Indian peacocks wandered into the yard. Sightings have traveled up and down the bay for several miles this summer, and this week, it was our turn for a visit. The editor of our bulletin asked me a few weeks ago about my hybridizing goals for PCI. A PCI with the brilliance of a peacock’s tail seems a very worthy goal!

2016 A GOOD YEAR FOR TALL BEARDED IRIS

By Dawn Mumford 

2016 was a good iris year for us.  The conditions in Utah were ideal (except for some strong winds that blew sporadically throughout the season).  We had an exciting season because we had so many "first time to bloom here" irises or "maiden" irises. Here are a few:

'Bravery' (Joseph Ghio, 2011)

This iris is very dramatic; it was very popular in our garden. The blue/white standards are a perfect contrast to the purple/black falls. To add even more contrast there is a bright tangerine beard.  This is a favorite. 

'Ocelot'z Lot' (Brad Kasperek, 2012)

This is a border bearded.  This is one of those irises that turned out even better than the advertised picture in the catalog or on the web page. I have come to have a real fondness, love even, of the broken colored irises that Brad is so famous for.  

 'Red At Night' (Richard Ernst, 1993)

This iris and 'Dynamite' are my irises that have the most pure red color without having the rust or brown in them.  It didn't fade and it withstood the rain without getting white measles. (which is a made-up term) 

'Eye For Style' (Barry Blyth, 2006)

Everyone raved about this iris.  It is justified.  This is a beige/pink (maybe mauve) color.  The lavender/blue blaze around the orange beard makes it more attractive. It has good substance, stays open a long time, and the branching is good. The pollen parent is 'Decadence' and so you may recognize the heavily ruffled form.

  

'Center Ice' (Joseph Ghio, 2009)

The standards are white with a pale blue edge tint that I find so attractive.  The falls are white with a rosy violet band.  The beard is pale yellow even if the catalog described it as cream tipped with white.  I would describe this iris as crisp.  Notice the bee trying to get in.  

'Golden Legacy' (Gerald Richardson, 2013)

This one is gold/buff with a violet base tint.  The falls are amber-gold, lighter below the yellow-orange beard.  This one got a little battered by the heavy sustained winds.  

'Louisa's Song' (Barry Blyth, 1999)

My heart swelled and my breath caught when I saw this iris. I love purples, lavenders, and orchid colors and this has it all.  It holds itself up proudly and the substance is heavy and this bloom stays open longer than usual.  Another favorite of mine. 

'Goodnight Moon" (Schreiner's, 1995)

This lemon yellow self is huge.  I think of it as generous.  The beards are a golden yellow.

'Heartfelt Beauty' (Margie Valenzuela, 2012)

The standards are pale lavender white. The falls are also pale lavender white with pale peach hafts. It has a beautiful red beard. 

'Peekaboo Zebu' (Brad Kasperek, 2005)

This iris from Brad is rich in red/purple color with white streaks.  It has tangerine beards.  Another broken color beauty to add interest to your garden. 

'Splurge' (Joseph Ghio, 2009)

When I ordered this I was afraid it would be too muted for my taste so this was a pleasant surprise.  The standards and style arms are pink. The falls are pink with deep coral on the shoulders with red violet veins and speckles. This was different but nice and not too muted.   

'Neutron Dance' (Barry Blyth, 1987)

This Amoena, white standards with colored falls, has fresh clean colors. It's standards are white but mine have a tiny rim of pale yellow,and the falls are deep yellow. The beard is also deep yellow.

'Dinner Talk' (Barry Blyth, 2005)

This was my first bloom of 'Dinner Talk'.  It had 4 falls but the subsequent blooms had the standard 3. It had luxuriant ruffles and a very heavy substance. This one will go on my new favorite list.  

'Persian Berry' (Larry Gaulter, 1976)

This 40 year old iris is so graceful and the blending of mulberry, lavender and orchid is glorious. The contrasting orange beard finishes it nicely. 

'Bubbling Waves' (Joseph Ghio, 2005)

Almost everyone who came to the garden this year asked what this one was. The color is described as simply blue.  The form is outstanding.  

'Slovac Prince' (Anton Mego, 2002)

The pod parent for this one is , 'Edith Wolford' and the Pollen parent is 'Queen In Calico'. The standards are pale lavender white with a tiny gold rim. It wouldn't be as attractive without that.  The falls are blue/purple with a lighter rim.   

'Pond Lily' (Evelyn Jones, 1994)

The standards are veronica violet , flushed deeper at midrib. The falls are also veronica violet with pink influence. The beards are tangerine.

This year I bought a new macro lens for my camera.  I had such a good time with it.  At first I cut everything off because I stood too close to the subject, but later I backed up some and was happier with the result.  It was fun to use it when I wanted more detail with a blurred background. 

Iris season was crazy and hectic and just wonderful. My husband and I just finished planting all the new rhizomes that I ordered from iris vendors. I look forward to many more maiden blooms next year or the year after, and there are still many from this year that I will show you in future blogs.

Happy gardening, and remember I love hearing comments from you because it is always fun to talk iris.

The Untapped Potential of Iris reichenbachii

by Tom Waters

Today's post is all about an underappreciated bearded iris species, Iris reichenbachii. The name, it seems, is bigger than the iris itself. I. reichenbachii is a dwarf, ranging in height from 10 to 30 cm (4 to 12 inches), with one or sometimes two buds at the top of the stalk. (Very rarely, a third bud may appear further down the stalk.) The flowers are yellow (often with brownish markings or blending), smoky violet, or occasionally clear deep violet.

Iris reichenbachii

The species is native to the Balkan peninsula, from Rumania and Bulgaria through Serbia and into Greece. A related species, I. suaveolens, is similar but smaller. Two other species names, I. balkana and I. bosniaca, are now regarded as synonyms of I. reichenbachii.

As a garden subject, I. reichenbachii is pleasant enough, if somewhat unremarkable. It has found a home with rock gardeners and plant collectors. For those who fancy modern hybrid dwarf and median irises, this little species can seem drab by comparison. The petals are rather narrow, substance is lacking, and the colors can seem a bit murky.

To the hybridizer, however, I. reichenbachii has something unique to offer. Its chromosomes are very similar to those of tall bearded irises, and it is quite compatible with them. Furthermore, I. reichenbachii exists in both diploid (two sets of chromosomes) and tetraploid (four sets) forms. Since modern TBs and BBs are tetraploid, they can cross with tetraploid I. reichenbachii and produce fertile offspring. (For an explanation of diploids and tetraploids, see my earlier blog post Tetraploid Arils, Anyone?)

'Progenitor' (Cook, 1951)
 from I. reichenbachii X TB 'Shining Waters'

In the 1940s, the talented hybridizer Paul Cook did precisely that. A seedling from the cross, aptly named 'Progenitor', was registered in 1951. It was an unimpressive iris of intermediate size, but Cook could see its potential. 'Progenitor' was a bicolor, with violet falls and pure white standards. At the time, this was a new color pattern. (Earlier bicolors were actually variations on a "spot pattern" from I. variegata, and seldom showed the completely solid falls and pristine standards of 'Progenitor'. It is interesting to note that I. reichenbachii itself is not a bicolor. The bicolor pattern resulted from combining its genes with those of the TB parent. By crossing 'Progenitor' back to high-quality TBs, Cook was eventually able to transfer the bicolor pattern onto irises that otherwise showed no resemblance to the modest little dwarf that had given rise to the new pattern. 'Whole Cloth' (Cook, 1958), four generations on from 'Progenitor', won the Dykes Medal in 1962.

Virtually all TB and BB bicolors today (standards white, yellow, or pink; falls blue, violet, purple, reddish, or brown) are descendants of 'Progenitor', and hence of I. reichenbachii.

But there is still more to be done with this interesting little species. When Cook was making his crosses, there was very little interest in dwarf or median irises. In fact, medians as we know them today hardly existed at that time. So Cook simply worked to transfer the new color pattern into TBs. Today, however, there is considerable interest in breeding medians, especially BBs and MTBs that are consistently small and dainty. Surely the little dwarf I. reichenbachii has something to offer in these endeavors. The tetraploid forms are compatible with BBs and tetraploid MTBs, while the diploid I. reichenbachii could be crossed with diploid MTBs. Since these sorts of crosses should produce fertile seedlings, a hybridizer could continue the breeding line to achieve any desired goal.

Iris reichenbachii

I. reichenbachii is a little difficult to find in commerce, but not impossible. Some specialty nurseries list it, and if one is willing to grow from seed, it shows up rather often in seed exchanges that include iris species.

If you see this odd little species available somewhere, why not give it a try? Perhaps even make a cross or two to see what happens...

My second bloom season

                                                                                 by Joe Musacchia

    In late June to early July, it starts all over again. Bloom, that is. Ever since Louisiana Iris Gardens in Central New York started handling my introductions some six years ago, I have enjoyed a second bloom season. What a joy to see my new seedlings blooming again. The colors in the North are even more vivid than they are in Louisiana. This is when we make the final decisions about what to introduce next year. 

   This is 'Fouchon' a cross of Patrick O'Connor's 'Zydeco‘ X my 'Pointe Aux Chenes'. If you are wondering where the name comes from, it’s a port at the mouth of Bayou Lafourche, where it empties into the Gulf of Mexico

 ' Fouchon ' 
' Zydeco '  X  ' Pointe Aux Chenes '.

     Then we have 'Gentle Memories'. This is Patrick O'Connor's  'Just Add Water’ X Harry Wolford's 'Edna Claunch'. This name came from the first time Mrs. M. J. Urist gazed upon a garden of Louisiana iris during her first trip to Louisiana. I made this cross to demonstrate how hybridizing was done. The cross took, and it turned out to be a good one.

' Gentle Memories '
' Just Add Water ' X ' Edna Claunch ''

  Here we have ‘Labrador Hollow'. This is my  'Ardoyne‘ X my 'Little General'. This is named for a natural area down the road from Louisiana Iris Gardens. It was found in seedlings brought up from Louisiana, and had its maiden bloom in the NY garden.

' Labrador Hollow '
' Ardoyne ' X ' Little General '

   Next is a fun one, 'Iko Iko'. This is a cross of Heather Pryor's 'Garnet Storm Dancer' X  Dormon Haymon's 'Grace Duhon'  This flower makes me want to party, so the name of the Mardi Gras song Iko Iko seemed appropriate

' Iko Iko ''
 Garnet Storm Dancer ' X  ' Grace Duhon ' 

   My last seedling, 'Cochon de Lait', is is one of many nice seedlings that came from a 'Pure Water' bee pod. This name translated literally from French is a suckling pig, but to a Cajun this means a party. More like a Cajun barbecue.

' Cochon de Lait '
' Pure Water Bee Pod '

Here are some more of the many Louisiana irises that bloomed in Central New York this year.

   As you can see Louisianas do well in Central New York. If you would like to extend your iris bloom season, by all means try Louisiana iris. All pictures here are courtesy of M.J. Urist of Louisiana Iris Gardens.  

Late Stalks: Rebloom Breeding in zone 6A

By Betty Wilkerson

Welcome to my garden.  I'm in Kentucky, zone 6.  Once again, it's been a crazy, crazy spring.  We had some really nice days during the last half of winter.  Good days to clean the iris beds and get ready for spring.  This is when it started getting crazy!  I suspect it was Mother Nature in stress mode, but maybe it was just the irises acting weird.  

Just a few days into the bloom season, it looked like a lot of the early things would not bloom!  Then, stalks started to spring up, or so it seemed, on the ones that should have bloomed earlier.  Everything was out of sequence.  However, it did make rebloom crossing easier because more flowers were blooming at the same time.  

At the end of bloom season, the inevitable depression set in.  It's generally over for another year (except for rebloom). Then I noticed extra stalks showing up. There were a couple on some of the new reblooming seedlings, and one on a slightly older seedling from rebloom breeding lines!

There's one on 'Cameo Blush,' and one on 'Over and Over.' 'Silver Dividends' also put up a stalk but with only two blooms.  (No other introduced irises bloomed at this time.)

'Cameo Blush' (Weiler by Friendship 1998)

'Over & Over' (Innerst 2003)  

Two of the seedlings from 'Tara's Choice' X 'Again & Again' put up stalks. The yellow one, 2152-02re, has cycle  rebloomed in the past and is in my older reselect bed with 2 stalks up.  2152-03 is from my previous "baby" bed and was not seen before.  It wasn't great.  No, I don't always plant all of a given cross at the same time. It depends on space and time, and what I want to see, but these were pretty and several rebloomed, so I planted all of them.


One of my disappointments has been 2527, a cross with 'All Revved Up' & X 'Lunar Whitewash.' 'All Revved Up' can bloom all summer and 'Lunar Whitewash' is a good cycle rebloomer, so I'd hoped for some type of rebloom, with good form.  I got form but none have rebloomed, yet. It was a bit surprising when some of these seedlings started putting up late stalks.

2527-05 ('All Revved Up' X 'Lunar Whitewash') 

2527-01 ('All Revved Up' X 'Lunar Whitewash)

2527-05 ('All Revved Up' x 'Lunar Whitewash')

 The latest developing stalks were 2145-01 ('Pure as Gold' X 'Summer Radiance') and 2603-04, a dark one from ('Lunar Whitewash' X Romantic Evening') X 'Over and Over.' A large group of 2145-01 crosses bloomed and were photographed in the spring, while 2603-04 did not bloom in the spring and this is my first time to see it.

2145-01 ('Pure as Gold' X 'Summer Radiance')

2603-04 (('Lunar Whitewash' x 'Romantic Evening') X 'Over and Over')

With three exceptions, all of the surprise reblooming has been on my seedlings which have at least one rebloom parent. My theory, and it's just a theory, is that I should take this as a signal that, if not rebloom, they have some type of "loosy-goosy" genes that allows later bloom.  One thing for sure, they don't put up these late stalks every year. Come to me, my favored children!

You've had another peek into the strange habits of mother nature as she works in and around Bridge In Time Iris Gardens.  For further reading about reblooming irises, visit the Reblooming Iris Society site  or subscribe to "The Recorder" through the website.
