November 2014

I planted this year's seeds on November 11. In the end, it was a disappointing year for most crosses, although I ended up with a plethora of Iris pumila and Iris attica seeds, most of which went to the SIGNA seed exchange (see here for a list of my donations with photos of the parent plants). Weather is to blame. Pumila season in April was great, but May was a roller coaster with a devastating hard freeze around mid-month.

April 2014

As of today (April 22), pumila season is winding down and the arils and arilbreds are just coming into bloom. I've made almost 200 pollinations so far, almost all intercrossing different pumila forms. If there is a lot of extra seed, I will donate some to SIGNA. It's been a very gratifying spring so far, as the seedlings grown from the first seeds I obtained in 2010 are coming into bloom: seven different I. pumila and three I. attica. It's also been a good year for the other pumilas growing in the garden. At least as far as this species is concerned, I feel finally "underway" with ample breeding material in hand. I also see lots of buds coming on many of the tetraploid arils, a most welcome development! Some seedlings are germinating now, more than last year at this time, although it still seems spotty and those I planted last autumn have not sprouted (yet).

March 2014

The first pumila opened March 18, and I pollinated it with frozen pollen from last year's 'Werckmeister's Beauty'. I got an apparent take with frozen pollen last year, but only when the seedlings bloom will it be clear whether the cross was true or not.

January 2014

Here are the crosses I made in 2013. The seeds were planted November 8.

September 2011

Now that most of this year's acquisitions have arrived and are safely planted in the garden, I've been thinking about possible crosses next year and how to prioritize them. Of course, last year's plans were derailed by the arils and I. aphylla not blooming, and I know next year will also have its own unexpected complications and obstacles. Still, here is what I'm thinking of doing.

Iris pumila will likely bloom first, and I have a range of different ones to work with now. First priority would be to pollinate them with tetraploid aril pollen, should any of the pumilas bloom late enough (or any of the arils early enough), to make this possible. Otherwise, the pumilas will be intercrossed, with excess seed going to seed exchanges.

The first priority with the oncocyclus species is to cross clones of the same species, if I should have more than one bloom. The goal is to perpetuate the species in my garden, and perhaps also have some excess seed for the seed exchanges. For oncocyclus that I have only one clone of bloom, and for diploid RCs, I hope to pollinate them with tetraploid arils or with I. pumila, in about equal numbers if possible. 'Aladdin's Gem' (for AAP triploids) is also a possibility here.

I have acquired many clones of Iris stolonifera and Iris hoogiana. I would like to cross different clones of the same species to perpetuate them. On an equal priority with this are tetraploid aril x tetraploid aril and tetraploid aril x pumila crosses. If I'm unsuccessful in diploid aril x tetraploid aril crosses, I will also want to try the reverse cross at least a few times.

I hope to have Iris schachtii and several clones of Iris aphylla bloom. I will cross the aphylla clones as a first priority, try schachtii x aphylla, and use the pollen from both species on BBs and other tetraploid medians. I also want to try aphylla x tetraploid aril and schachtii x tetraploid aril (and perhaps the reverse crosses, if timing and quantity of aril bloom permits).

I have Iris reichenbachii from several sources, and will intercross them and try them on tetraploid medians to test for tetraploidy. (I  suspect they are all diploid.)

I'd like to try any surplus pumila pollen on smaller tetraploid medians, to see if I can get diminutive plants of the PPTT type, fertile with SDBs.

I also want to try pollinating the tetraploid medians with pollen from tetraploid arils, particularly Regelias.

I have some smaller AATT arilbreds ('Anacrusis', 'Wadi Safra Moonlight'), which I may cross with each other or taller ABs for arilbred medians in the AATT family.

That's the basic part of the plan, contributing directly to my work with the tetraploid fertile families.

There are also some crosses I would like to try in order to learn something, or for fun. These are a lower priority.

TT diploids: I seem to have ended up with a large number of different I. suaveolens plants. I will intercross them, and use their pollen on other diploids (MTBs, 'Mme. Chereau' and 'Swerti', 'Buddha Song' and I. pallida variegata). I also have I. timofejewii, which will be used similarly if it blooms. I'm picturing miniature little irises with variegated foliage...

If Iris attica blooms (I hope to have two different clones), I will intercross them and also pollinate some with I. pumila.

I want to try 'Zwanenburg' pollen on SDBs, to test if it is really APTT rather than AAPT as is usually supposed.

Finally, I want to try some crosses not expected to produce fertile offspring, just for the experience of doing them. These will include using 'Aladdin's Gem' on SDBs and ABs, SDB x AB crosses, and TB x AB crosses. I may also put diploid aril pollen on my diploid dwarf species for diploid arilbred dwarfs.

That sounds like a lot, but I know it is better to have too many things in mind than too few, the way plans tend to go awry. Making this table was an excellent exercise in sorting out all the many ideas in my head and pulling them into something resembling a plan. Here's a summary, grouped by pod parent, as this is a scarcer resource than pollen. Organized this way, when something blooms in the garden, I can immediately see what my options are and make the highest priority cross I'm able to.

May 29, 2011

The hybridizing season came to a close yesterday when I pollinated the final bloom of 'Enchanted Mesa'.

May 17, 2011

Wrapping up the season with a few crosses not in my original plan: Iris reichenbachii pollen on 'Enchanted Mesa' to test whether this clone may be tetraploid, 'Baby Blessed' on 'Catchy Name' just because both are rebloomers, and a different Iris pumila clone on the second stalk of 'Azure Whir'. I'm not optimistic about any of these, as the TBs are severely frost damaged and the flowers are all malformed.

May 10, 2011

The first TB opened today, 'Azure Whir'. The bloom showed some damage from the frost at the beginning of May, but I pollinated it with Iris pumila. Since the arils are not blooming this year, I thought using the pumila pollen on TBs might be interesting, so that I could learn about this classic cross for SDBs first-hand.

May 5, 2011

Iris reichenbachii bloomed today. I do not know if this particular plant is diploid or tetraploid, and no other TTTT type has bloomed yet. I polinated it with I. pumila pollen, since it looks like my tetraploid arils will not bloom this year, and so there is now no special need to conserve pumila pollen. If the I. reichenbachii is indeed tetraploid, the cross should produce amphidiploid dwarfs compatible with the SDBs. The cross was difficult to make, the bloom being so small.

April 11, 2011

Instead of intercrossing my Iris pumila plants, I have decided to hold their pollen for use on the tetraploid arils. It looks like there may not be a lot of bloom on the pumilas, and I already have many pumila seeds planted and plants on order, so I no longer see a great need to produce more pumila seedlings.

I also plan to make some crosses outside my main breeding program for learning and for donating to seed exchanges.

September 2010

This coming spring, I expect bloom of several different clones of I. pumila, the two regelia species and two tetraploid aril hybrids, and perhaps I. aphylla and I. reichenbachii. The pumilas will likely bloom first, so they will be intercrossed. I. pumila pollen will be used on the tetraploid arils in hopes of starting a line of arilpums. If I run out of I. pumila pollen before running out of aril blooms, I will likely intercross the arils or perhaps pollinate them with aphylla pollen. If aphylla and reichenbachii bloom, they will be crossed to test whether the reichenbachii plant is a tetraploid. I may also try some aphylla x pumila crosses if there is more aphylla available than reichenbachii.
