Some of My Best Rebloom Parents in Zone 6

by Betty Wilkerson

'Earl of Essex' has been used by many people and it has produced many rebloomers, but I'm not sure it has received all the praise it deserves. It is one of my favorite parents due to the fall form, which is round, and its willingness to pass on its rebloom genes.  On the negative side it is a cycle rebloomer, it is short, and it is a plicata.  Those are drawbacks because I work with summer rebloomers, prefer tall seedlings, and dislike the messy hafts that come along when crossing plicatas and selfs.  I've been told that the messy hafts come along with the plicata breeding since they have not been removed from the plicata gene set, and although these genes are not specifically a part of the plicata gene, they ride along with it.

Common sense tells me that the shorter plant should be used as the pollen parent with the taller plant being the pod parent, but this is not possible when you don't grow both plants. Sometimes we get pollen from other growers, you see.  A friend donated pollen from 'Hot Streak' (Ghio 1999) and I crossed it to 'Earl of Essex', and 'Radiant Bliss' was the result.  I'm extremely glad I didn't follow common sense!

Once I moved to Mitchell Weaver Road, and established a short row of 'Radiant Bliss', I looked for a rebloom partner.  'Summer Radiance' stood tall and proud just a few plants over.  Both plants are tall, so it wouldn't matter which was taller, but 'Summer Radiance' rarely sets pods so I used it as pollen parent.

There were several seedlings from the cross that rebloomed, and although some were red, the best one I named 'Summer Honey.'  In 2011 it managed to bloom from spring through fall freeze.  It was a nice, relatively moderate summer, and I did water every ten days or so when there was no rain.  I received a letter with pictures of it reblooming in Oregon in 2014.  It was gorgeous.

Below is a picture of the stalks that were cut down in the fall freeze of 2011. Five stalks growing from one rhizome.

'Radiant Bliss' was crossed onto 'Innocent Star,' resulting in five rebloomers. 'All Revved Up' is one of these rebloomers.  It passes rebloom on to many of it children.

'Rebound' (Wilkerson 96) was used on 'Innocent Star' and produced 'Echo Location' and four other rebloomers.  Below is a picture, showing the netting beside the beard, that I understand indicates it is a plicata.  'All Revved Up' and 'Echo Location' share 75% of their genes.

'Echo Location' was crossed onto 'Again and Again.'  There were three rebloomers, but 2130-01Re is the only seedling I kept from this cross.  It's not as pretty as I thought it was in maiden bloom.  It was a solid purple self in maiden bloom, but this is what it looks like now.

I've crossed 'Over and Over' onto this seedling.  Many have been planted and some may bloom this spring.  Stay tuned for an update on the seedlings.

Dominance and Patterns in a Reblooming Iris Cross

By Betty Wilkerson

Most of you know that I’m not an expert on iris genes. I’m going to take you down my garden path so you can see some of my seedlings. The plicata pattern has never been my favorite. I didn’t have a lot of options in the beginning, or when the irises, and I, moved to Allen County during the fall of 2003. 

In the spring of 2004, a couple of the brightest blooms were ‘Radiant Bliss’ and ‘Summer Radiance.’  This was not a cross I’d planned, but it did make sense.  ‘Radiant Bliss’ is a tall, well branched rebloomer and tall, well branched iris make the best pod parents.  It's a fall cycle rebloomer.   ‘Summer Radiance’ had refused to set pods and was being used as a pollen parent.  'Summer Radiance' is without plicata in its geneology and it reblooms in July and then in the fall.  

Genetically speaking, solid color selfs are dominant over plicata.  What does this mean to people that have never made a cross?  When using a self, in this case 'Summer Radiance,' that has no plicata in the parentage, none of the children will be plicata.  The children will be a mixture of variegatas, bitones, bi-colors, and blends, with possible overlay or apron patterns.  Many will have lots of haft lines & murky colors.

In a cross like this, many seedlings will be some version of a solid color.  Some will have haft lines, like the ones in these pictures.  Some colors will be clear, while others are murky.

More exciting, for me, would be the variegatas.  I had hopes one of these would rebloom, but no such luck.

There were several red seedlings.  One (not this one) did try to rebloom, but really late.  I saw it as winter bloom. Haft lines were bad on the red ones.

'Summer Honey' (Wilkerson 2013)

In the end, 'Summer Honey' (#1814-02re) was the star of the crop.  She fall bloomed for several years.  During the summer of 2011, after a lineout planting the year before, 'Summer Honey' bloomed each day from spring bloom until the first fall freeze!  It was a good sized planting, but still nice to have bloom all summer.  Could a good sized planting be the solution to continuous bloom?
