Iris pumila: a Tiny Treasure

by Tom Waters

Iris pumila

In an earlier blog post, I wrote about how the tiny bearded iris species Iris pumila was imported to the US by Robert Schreiner in the 1930s and crossed with the popular tall bearded irises, giving rise to a whole new type of garden irises, the standard dwarfs (SDBs).

Today, I thought I would write about Iris pumila itself. Besides being an extraordinary find for iris hybridizers, it is a delightfully varied species that makes a wonderful garden plant. It is invariably the first bearded iris to bloom in the spring, starting several weeks before most of the hybrid dwarf cultivars.

In the wild, Iris pumila grows in a wide range across eastern Europe, from Austria in the west through Hungary, Romania, Ukraine, and into the Caucasus Mountains as far as Armenia and even Turkey. It is often found at higher elevations and dry, continental steppe climates. It is adapted to cold winters and sunny, open spaces. Conventional wisdom has it that Iris pumila does best in areas of colder climate (USDA hardiness zone 6 or colder), although I have grown it in southern New Mexico (zone 8), so it may be worth a try even in warmer areas.

Iris pumila is among the tiniest of bearded irises, with the tip of the blooms only about 10 cm from the ground. Usually, the stem is so short as to be hardly detectable; the blooms are held aloft on an elongated perianth tube, so that each bloom seems to be just sitting atop the rhizome from which it grows.

The species shows a phenomenal range of color. To judge from pictures I have seen on the internet, Ukraine seems to be the center of its diversity, with many extraordinary color combinations seldom seen in plants that have been imported to the US or western Europe.

The basic color may be blue, purple, yellow, or white, in any shade from pale to intensely saturated. There is almost always a darker "spot pattern" on the falls, which may be small or may cover virtually the entire petal. The spot may be solid color, or appear as rays or veins or an uneven wash of color.

You can find Iris pumila offered for sale by some alpine or rock garden nurseries. (A word of caution: non-specialist nurseries, like garden centers, often use "Iris pumila" to label any small bearded iris cultivar; these are not the true species.) Many seed exchanges have it, and growing from seed can be extraordinarily fun, since every seedling is different. It does take some patience, however, as irises take 2 to 3 years to bloom from seed.

There are also named cultivars of Iris pumila available from specialty iris growers. Many of these are registered as miniature dwarf bearded (MDB), since they meet the definition of the class. More recently, some have been registered as species (SPEC). One very popular Iris pumila cultivar is 'Little Drummer Boy' (Willott, 1997), which won the Caparne-Welch Medal for best MDB in 2005.

Some newer Iris pumila cultivars include 'Steppe' (J. Burton, 2011), 'Keystone Oracle' (Jesberger, 2011), 'Wild Whispers' (Coleman, 2012), and 'Royal Wonder' (Coleman, 2013). 'Keystone Oracle' is notable for turquoise tones around the beard and spot, which varies from dark to pale depending on climate.

I hope I've given you a taste of the beauty and variety of this diminutive iris species. Have you tried growing any Iris pumila in your own garden?

'Scottish Reel' Dances in the Garden

By Renee Fraser

The dominant colors in my garden are screaming salmon-orange, yellow, and orchid.  I have restricted the color palette to bring some order to the chaos of an inveterate plant collector's garden.  It works.

So what to do with a spectacular coppery-gold iris that shines like a beacon of light?

'Scottish Reel' with annual Paludosum daisies

'Scottish Reel' is a Barry Blyth iris from 2001.  It grows to between 34 and 36" tall, and blooms  early to mid-season.  There are two or three blooms per socket on this iris, which extends the bloom period.  The foliage is very nice: straight, with no corkscrewing, and the plant is tough.

Since I have been unable to find a spot for it, this iris has been moved each year. It started out in the vegetable bed, was moved to the garden, then back to a different part of the veggie bed where it was exposed to root knot nematodes, then I dug it up, cut off all of the roots to the rhizomes to get rid of any nematodes, and planted three in a pot last year.  All three bloomed this year!

My resolve to keep only plants that complement my existing color scheme is broken by the loveliness of this iris.  I will always have it in my garden, even if it is relegated to the vegetable beds.  Do you have an iris that you keep in your garden even though you have no place to plant it?  Share it with us in the comment section below.

The Joy of Maiden Blooms

                                                         By Joe Musacchia

     One of the most exciting times for a hybridizer is spring bloom in the seedling beds. You go through the winter with great anticipation of the upcoming spring to see what your work has produced. Over time you learn that only one in a hundred may be a really special iris, but as the stalks start forming, there is always hope that maybe this year there will be more good than bad.  Finally the morning comes when first color shows. You start watching the weather reports. Is there a late freeze? Any storms coming with hail? All is good, and they have started. What excitement! Then the evaluating starts: how many bud positions, how strong is the stalk, is the color fading, is it different than mama?  Maybe we will keep this one another year. But then, HEY! Look at you! Aren't you something. This is what it's all about: the emotional ups and  downs going through the seedlings one by one, looking for that winner. 

    These are pictures of my 2016 maiden blooms. Much evaluation remains to be done, but I thought you might like to see what I saw when they first opened. 

    'Hush Money' has produced some real nice kids:

12-46-1 stalk

12-46-1 'Ginny's Choice' X 'Hush Money'

12-46-2 'Ginny's Choice' X 'Hush Money'

'Hush Money' X  'Tchoupatulous'

I have been trying to make a cross with 'South Yara Darling' for several years, and finally it happened:

13-05-01 'South Yara Darling' X  'Pointe Aux Chenes'

-

 

 This is a seedling that was lost and found last year, and this is its first time blooming in my garden.

08-03-01  'Charlotte's Tutu' X 'Honey Galore'

 'In The Navy' X 'Our Sassy'

   Another difficult cross was with 'In The Navy'. Here is a first look at 'In The Navy' X 'Our Sassy'.












 

'Simply Irresistible' X 'Pink Poetry'
05-22

'Queen Jeanne' X ' Mardi Gras Mambo'
12-31

This one was a real surprise. At first glance I thought Court Jester. But that name is taken.















I hope you enjoyed seeing my maiden blooms. Hopefully in the future you will see one or two introduced with their new names. Here is wishing everyone a wonderful bloom season.

Children of 'Over and Over' Part 2- Breeding Reblooming Irises in Zone 6, Kentucky

by Betty Wilkerson

Just a reminder for those that are following this blog about 'Over and Over': many breeders do not consider 'Over and Over' to be a good plant due to its tailored form.  It's my intention to change some opinions, if I can. My approach on these crosses was to use well formed seedlings with 'Over and Over.'  In this crosss, the pod parent is seedling 2016-03 ('Lunar Whitewash' x 'Romantic Evening') and the pollen parent is 'Over and Over.'  

2016-03 (Wilkerson seedling) 

'Over and Over' could and does produce plicatas, but only if there are plicata genes in both parents.  While there are some plicatas in the background of this one, they are far enough back that they are unlikely to produce plicatas.  There are still many seedlings from this cross to bloom, probably this spring, which I expect to be loads of fun.

2603-01Re (Wilkerson seedling)

Seedling 2603-01Re, above, contains both 'Lunar Whitewash' and 'Over and Over,' two of Sterling Innerst's last introductions. 'Lunar Whitewash' has terrible branching, so I've been taking a chance with it, but this one was born with nearly perfect branching.  'Romantic Evening' has been added to my lines to improve color depth and variety.  I hope to breed some pinks to these in 2016.

As stated in my August blog, some breeders don't want to use 'Over and Over' due to form and branching. Again, I took a chance.  This picture shows maiden bloom and branching of a seedling.  In the years to come it can change, for better or worse. The bloom was late this year, but it this too will change as years pass.  I've no way to see into the future. This set of parents should be good for rebloom, so stay tuned for more chapters from this mystery.

In summation, my garden is filled with seedlings that are only half rebloom.
On Facebook, I have an album full of the earlier ones that I may still use in this program. In the future, my breeding time will be spent trying to combine these "out crosses" to improve the overall quality of my reblooming seedlings.  Most any strong rebloomer, older or modern, may show up in these seedlings.  I'll report it all.

Several months ago, I found I'd run out of photos.  I've rerun some and used others that didn't make me proud, with the old stalks and everything.  I figured if the perfection of the pictures was more important than the content of the story, that someone would let me know.  Starting with the next post, I hope to have new and better photos.
