In terms of cold hardiness, I wouldn't necessarily look to aphylla. At
least not for that purpose alone. Aphylla has a unique form of
dormancy, that may be quite different then other dormancy. It is a
photoperiod dormant. Triggered into dormancy by the decreasing
daylength in fall. Once dormant, it won't break dormancy until it has
had the required cold period. I have done some interesting experiments
on this.
If cold period occurs before triggering photoperiod, the leaves
freeze, the same way as with so called semi-evergreen daylilies.
Mixing aphylla with a cold period dormant plant, in first or second
generation will produce plants with mixed dormancy, and lack of
vernalization gene for flowering and you get some fall cyaclic
rebloomers in seedlings.
Aphylla has the genes fro anthocyanin enhancement "Ae" which are
dominant. they enhance the colour of the anthocyanin by producong
Anthocyanin Vascular intrusions, which are solid protein based globules
of anthocyanin inside vacuoles and thus enhancing the pigment
colouration.
For cold hardiness, just get some of my proven cold hardy plants, bred
to survive my harsh winters, without consitent snow cover. Check out
how many have won Loomis awards.
If anyone wants some seeds of Yellow Conunfrum, let me know. Thare are
always lots, but they are open pollinatd. There are lots of differerent
aphyllas nearby, as well as many other iris.
I suspect a lot of different untapped ge
netics in aphylla. But I like
thin stalks and high bud count and low branching. The Yellow Conunfdrum
is producing some unusual colours in seedlings, many which appear to be
pure aphylla.

So I know that I am interested in cold hardiness in aphylla bred iris,
but I would love to hear what others are hoping to accomplish by using
I. aphylla or aphylla bred iris in their breeding programs.Bill

Nice to hear about others interested in I. aphylla. Although I
have only started working with it directly, I have a few hybrids
involving it from Harald Mathes, which I am using in my aril program.
Looks like I need to get ahold of 'Dolce' for some further work. I
find the flower quite smart looking, as well as possibly being good for
pinks in the aril-breds. Does anyone know of a source in Europe? Or
for the yellow aphylla. I know Harald had one, as he used it in the
plants I am growing, but additional clon
es would be an asset.
Also
, as the season is right, does anyone have any seed of I. pumila
to spare? I have two plants purchased as I. pumila, but
neither go completely dormant in the Winter, so I have my doubts.

For the record I also am doing some breeding with aphylla, as well as
some crosses with pumila, including some pumilla X aphylla crosses
which should bloom next year.
Some very neat things comming out of aphylla h-17, or as it has been
registered Yellow Conundrum.
Lyn Markham has gotten some not-anthocyanin flowers first generation
from a purple aphylla, but it is rare.
Also some plicatas will show up in unexpectadly high ratios in second
generation

Dear Bill: I am delighted to see another person interested in
hybridizing with species. Brad Kasparek also has a hybridizing program
involving aphylla as well as Stephanie Markham and Cindy Rust. The
Craigs have done some fantastic work but in my mind have not been
adequately recognized for all they have done.
If you are looking for immediate recognition this is not the path to
take. New ideas have been always been scorned by the establishment.
Years ago people discouraged ruffles and lace as deformities. Horned
Iris are still dismissed by some purist. Over a decade ago I20campaigned
to created the category SPECX.=2
0Many still do not understand the goal of
this class is to encourage innovation. It also allows
every plant to
come into the awards system. I am constantly explaining that it
includes every hybrid iris and with the species Iris, all Iris fall
within these two categories, all other classes are refinements and have
narrower paradigms. Enough of my soapbox.
I hope to do some hybridizing with aphylla also. I have no goals that I
am trying to develop but just interested in experimenting to try to
understand the species and see what it may do. Like Cindy I intend to
do some crosses with Arils and also MDBs to groups that I have a great
fondness for.
If you are planning to use aphylla be aware that the species is quite
variable. The common purple-flowered forms, often carry dominant genes
for that color so that if you want to have a lot of color variation,
you must seek out the white or paler purple forms. Another problem I
have as a species advocate is that, when one uses a cultivar name
people assume the plant is no longer a species. Cultivar names are the
best way of distinguishing the different forms of a species but of
course they are also used for hybrids. It drives me nuts that many
species forms are disseminated under collection numbers like B-12
instead of a legitimate cultivar name. A registered cultivar names
provides an official reference to a description and other informa
tion
whereas the numbers and letters
often get lost or transposed.
I hope you are toleran
t of my rants. I am working on a project for
SIGNA that will show how species are distributed throughout the
country. If you would like to take part I will send you a one page
survey.
