Crosses in 2013
My labor
of love is to create unique reblooming irises for cold climates, but nothing is
reblooming in my garden right now, so I thought I'd take you into the
reblooming fantasy garden of my mind.
How can I do that? By showing you
irises I have hybridized that have reblooming genes that I intend to cross
again to get reblooming irises in a wider variety of colors.
A few years
ago, Australian hybridizer Barry Blyth recommended that hybridizers take
pictures of the parent flowers as they make crosses. Such a brilliant
idea that I should have thought of it myself! (insert smiley face) So
now I carry a digital camera in my hybridizing bag, along with notebook, pen
and hybridizing tags. The trick is to remember to take the pictures when I make
the cross! So the photos below are my
field pictures, part of the documentation of the painstaking and lenghty
hybridizing process of producing better flowers for your garden.
People say they are tired of the "default"
rebloom colors of yellow, white, and purple. These are basically the
result of dominant genes. Other colors and some patterns require the use
of recessive genes. Over the past ten years, I've worked to fold in patterns
and colors that did not exist in older cold climate rebloomers. Recessive
genes are required for the tangerine factor. This is how we get pink,
orange, yellow with a red beard or white with a red beard. Certain
patterns, like the Emma Cook pattern, are recessive. Plicata is even
recessive to selfs or single colored irises. For the past ten years I've
been working hard to fold these recessives into my seedlings.
This year, I'm crossing back for rebloom. It's going
to be difficult since the summer rebloom genes appear to be among the most
rare! I've crossed my reblooming irises and seedlings (irises that have
not been registered or introduced) onto each other, and to a few seedlings with
half rebloom genes that refuse to rebloom for me, in an attempt to achieve this
goal.
One such
cross is, well, YELLOW. Although I'm not crazy about all yellow
irises, I'm fond of most of these 'Summer Radiance' children,
due to their improved form and their intense colors. This 2013
cross will be used to get a nicely formed and vivid rebloomer.

Once
again, 'Summer Radiance' was outstanding, and its pollen was
very fertile and it took on several things. From the rebloom perspective,
there is a lot of potential in these new seed pods!

I have a
number of seedlings I call "The Kitchen Sink Kids" because they have
so many different genes in them that come from a reblooming iris numbered 1810.
( 1605-01:9415-1Re((('Victoria
Falls' x 'Vanity') x 'Immortality') x ('Latest Style' x 'Glistening
Icicle'))) x ('Feedback' x 'Champagne Elegance') X 'Light Rebuff.' for those of you who must know.) It seemed like a good idea to hit them with a
bunch of rebloomers. There were several good takes on 1810-15Re
below, the best rebloomer, and one take
on 1810-01Re. There were over twenty rebloomers, some summer and
some fall, from this cross. Sadly,
none met my requirements for introduction. Here are two of the parents from
1810 I am using to get better form and color in rebloom.

Pollen
from ‘Summer Radiance,’ a
known parent of rebloomers, took on 1810-01Re. I have several
more to share with you on my next post, so stay tuned!
I'm
finding 'Renown' to be a good
parent for plant qualities, but unfortunately, none of its children have
rebloomed. Pollen from seedling #2310-02 ('Decadence' X 'Renown,') ‘About
Tomorrow,’ and ‘Returning Chameleon’ took on
1810-15re, which is exciting, because 1810-15-re often blooms all summer and
into fall. 'About Tomorrow' is from 'Treasured' x 'Renown' and
gives beautiful and diverse children. I just can't wait to see these babies.

Even
though it was a bad year for hybridizing, I was able to get a dozen good reblooming
crosses for the future. For the next step, I stripped blooms from the
large plantings of my strongest rebloomers, 'Returning Chameleon',
'Summer Radiance,' 'Echo Location,' 'All Revved Up' and 'Star Gate' and carried them from bed to bed looking
for good mates. More about these later!
I also used
a number of seedlings that are rebloomers, but haven’t met my criteria for
introduction. But hope springs eternal in the world of reblooming iris
creation. Wish me luck!
Do you
have any questions about how your lovely rebloomers are created? Leave your questions and comments below and I
will do my best to answer.
