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.)

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.

 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.

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!

Breeding Tall Bearded Rebloomers in Kentucky: Focus

By Betty Wilkerson

The shortest point between two objects is a straight line.  If you want  to create rebloomers, even fall rebloomers, you need to cross two rebloomers.  'Feed Back' and 'Violet Miracle' were a part of my early collection.  They are both purple and were quite popular at the time.  'Feed Back'  produced many rebloom stalks throughout the summer, but often produced short stalks. 'Violet Miracle' is tall and well branched but doesn't rebloom a lot in my garden.  A cross between the two seemed to be a reasonable path.

A direct hit came from crossing 'Feed Back' x 'Violet Miracle' which produced 'Star Gate,' which has great branching, a great bud count, and reblooms in many zones within the US.  I would have preferred to reverse this cross but it just didn't happen.  'Star Gate', though, has helped produce a number of rebloomer seedlings in various shades of purple and white.

Two of these reblooming seedlings produced my rebloomers 'Another Bridge' and 'Theme Master.' CF2-1Re: (A1-1Re: ('Autumn Encore' x 'Roman Lover') x 'Feed Back') X G18-1Re: (E38-1: ('Orbiter' x 'Feed Back') x 'Violet Classic'). The three strongest seedlings survived and all three rebloomed, but only these two were introduced.

Most of these have been used, with various success, in an attempt to produce red rebloomers. 'Star Gate' has produced many red seedlings still being used in my red program.  Only the future will tell what may result.

Breeding Reblooming Irises: An Eye to the Future-2

An Eye to the Future-2.

People love to talk about their favorite finds in the seedling patch.  Dr. Lloyd Zurbrigg talked about ‘Renown’ because it was a seedling that rebloomed well for him.  Then he introduced it in 1992.  There were many reports of it reblooming throughout the country.  After a false start (growing an iris as ‘Renown’ that was incorrect) I finally got the real ‘Renown’ the summer after I moved to Allen County in 2003.  The first bloom was ugly and I questioned the authenticity.  In 2005 I grew ‘Renown’ it an upper bed and it blossomed very well!  I’ve used tons of pollen from this bed, since my final success.  ‘Renown’ reblooms in garden zones north of mine, yet only one stalk has developed here in the off season.  

'Renown'  (Zurbrigg 1992)

I decided to do some serious breeding with ‘Renown.’  It was a bit of a research project for me and there are several seedlings that I like. At this point, my favorite ‘Renown’ seedling, 2155-01, is from (Treasured x Renown.)  This seedling was a sole survivor from about 50 seed.  It has given some lovely seedlings.  I was going to name it ‘Wormhole,’ but I was told the name would offend Dr. Zurbrigg!  Hope springs eternal in my reblooming heart, so it’s been introduced this year as ‘About Tomorrow.’  It’s my belief this is a very good iris.  It’s not missed a spring since maiden bloom, it has always given a good stalk to fan ration, and it’s very pretty, for a white!

After a winter of gnashing of teeth, and wringing of hands, I decided to spend my 2013 spring working toward strong chances of rebloom.  Only a handful of irises rebloom well here, so I decided they would be a good match with ‘About Tomorrow.’  I was also looking for tangerine beards so I searched the blooming irises for something that rebloomed for me and had the right beards.  Seed are now waiting to be planted from ‘About Tomorrow’ by ‘Cameo Blush’ and ‘Summer Radiance.’

'Summer Radiance' (Wilkerson 1996)

One day I had a couple of blooms in my hand and didn’t know what to do with them, so, now, I have seed waiting from ‘About Tomorrow’ X ‘Star Gate.’ Although  'About Tomorrow' is white, I expect this cross will breed to the blue/purple side since the two share ‘Violet Miracle’ genes.

'Violet Miracle' (Zurbrigg  79)

At the end of August, I’m enjoying bloom on 1907-10Re.  It is a sibling of ‘Cool Character.’  1907-10Re bloomed all summer in 2011 without missing a day. It looks like I need to line this one out and consider introducing it.  It's still purple but it has many good qualities. Maybe the next generation will have other colors!  

1907-10Re (Wilkerson seedling) 

There are more seeds resting in the envelope rack.  They will all be planted in pots this fall.  Once again, I’ve enjoyed sharing the workings of my mind and the reasoning that went into making the latest crosses.  Will any of them produce good rebloomers of introduction quality?  I really think the potential is here.
