Post by: arillady on March 08, 2014, 10:41:08 AM
Miriam what stunning photos. Is it baby plants of Iris mariae in the foreground of the first photo or are they another bulb?
Iris hieruchamensis is certainly a special aril with its striping. So much pollen in some of the closeups.
Just being able to see them in their natural habitat is so special. Wonder how many truckloads I would need of sand??? But then we would probably get more rain than the Negev Desert so substituting with small gravel might be the better option.

Waooo ! seems that I've missed a lot of treasures  :)
Thank you for sharing this pictures. Onco season is starting in the wild too, which is nice !
I hope to contribute soon….
Oron, your Iris swensoniana is… Perfect ! as nice as in nature !

looking forward to seeing more soon.

Marvellous pictures of these plants Oron and Miriam.
We just have to consider a visit in the near future. 

Hans, when was your open-garden day again ??  :D
Title: Re: Oncocyclus Iris 2014
Post by: Hans A. on March 10, 2014, 10:02:42 AM
Hans, when was your open-garden day again ??  :D
Whenever you want, Luc - only next month, I will not always be there.  ;)

One of my favourite Oncos is without doubt Iris damascena - unfortunately this species hardly produce any seeds with me. Of about 20 flowers perhaps 4 pods are produced, half of them normally without seeds, the other two produce between one and three (!) seeds.
Despite of handpollination the resulting seedlings are often hybrids - in the last six or seven years  I was able  to grow only 2 plants which I would call pure species so far, second I discovered yesterday when it opened the first flower.
On the left side is the flower of the seedling, on the right one of an old plant.
The hybrids of Iris damascena I have seen look very different to the species - second picture shows an example, not bad with huge flowers, but not the species.
Another  damascenahybrid I showed here: http://www.srgc.net/forum/index.php?topic=9952.msg271643#msg271643 (http://www.srgc.net/forum/index.php?topic=9952.msg271643#msg271643)

Hans, I. damascena its one of my favourite as well,  one you cant take your eyes off when flowering... here is another one from few days ago.
Title: Re: Oncocyclus Iris 2014
Post by: Darren on March 26, 2014, 06:07:29 PM
Lovely to see these pictures of I.damascena.

I'm really excited because my plant of damascena has four flower buds and this is the first flowering for me so I can barely wait to see the flowers. Only a few more days to wait - and I'm off work next week so I will be able to enjoy it too!

Pat, i have relocated my entire bulb collection where i have now optimal conditions.
My Oncos are now fresh and clean from Viruses, from seeds sown since 2011.
They have never looked so compact and happy...

If you grow plants as well as Luc does - and I have a friend in England who is just as capable - people will give them plants to grow them to their full potential.

An added bonus is you might get one back  :) ;D ;D :)

Udo, not easy to say if it I. damascena or not; looks a bit too pinkish for me and leaves should be falcate, but depend of the growing conditions (light).
regarding your plant from Turkey, for sure it's not I. paradoxa, but it has blood from this species  ;) natural hybrid with I. sari ??

Here is another I. sari blooming now

Hello, I grow a few Onco Iris, and grow them in pots under glass as I live in Toronto, Canada. Do Onco's like to be pot bound, or should they have space to encourage bloom, and growth. Mine fill the pot , and I wonder if perhaps I should repot them into  larger pots once dormant.

Thanks,

they can be grown pot bound so long as they have enough food. use low nitrogen.

My experience is that they perform better in small pots if you want to grow them in pots. 
However they grow much better planted out in covered coldframes/raised beds.

You can grow many Turkish, Syrian and Iranian Onco outside in a sunny spot in Toronto and the plants will increase quickly.  some of the Iris from Israel are not hardy here.

Iris kirkwoodii, sari, paradoxa, uremensis, acutiloba and elegantissima all grow outside in SE Michigan without winter protection as long as they are in  full sun, sandy soil and dryish in summer.

Find a sunny spot with a rain shadow like near a building on the sunny side- i use south- southwest. and put 4-6 inches of builders sand overtop the local soil and plant the onco iris in the sand, the plants will be very happy there. No to little water in summer which seems to be the weather pattern here in the Great Lakes area. A friend nearby just uses his vegetable garden and put 4 inches of sand over top the garden soil and he always send surplus iris to the Aril society sales.  I have too many earth worms that mix up the soil so i put a landscape cloth barrier below the root level to keep the sand free of clay turned up by the worms.

I expect Iris kirkwoodii will start flowering this weekend

Hi Ruslan,
               What a wonderful set of photos.   It certainly shows the sort of variation that exist whilst all examples are still camillae.   And that there is enough of a population to show that variation!   Let's hope that it remains a viable population.

Ruslan, fantastic photos of this very variable species, wonderful to see it in its habitat, thanks for showing!

Good looking and well grown urmiensis Tom.

Here is Iris westii which i took a photo two days ago on Mt. Hermon, there was the last flower in bloom for us.
It is a solitary colony in that area, main populations are much farther north around Jezzine in South Lebanon.

Oron and Ruslan,
very nice pictures Iris of the natural location.

Fred, in my opinion is Iris polackii smaller in the flower and has this striking dark spot which Iris barnumae is absent.

Here my last in the greenhouse, Iris urmiensis from Iran.

Yaki you do grow the arils well. Unless there is streaking in the flower stem as well I would say it is not virus. Your clump of Iris haynei is stunning.
Title: Re: Oncocyclus Iris 2014
Post by: Yaki on May 23, 2014, 10:22:38 AM
Thank you -  Pat.
Actually, the big clump you refer to is I. Mariae.
As I wrote above, I'm not 100% sure of the identification, partly due to the fact that they grow so well in a soil that is very different from the sandy soil that is typical of the I. Mariae's native habitat. Also, they get more rain here, but they don't seem to mind. Unfortunately, I suspect that I only have a single clone, making propagation more difficult.
Yaki.

I've been slowly rebuilding my Onco collection for the last couple of years and I'm pleased with the ones which have flowered for me this year:

I. damascena. First flowering from a division obtained only two years ago and it produced 5 flowers  :)  However - it did go dormant quite early and the leaves took on an almost virussed look as they died back. I have separated it and will keep an eye on it next season.

I. nigricans.

I.sari - a small form

I. (iberica) elegantissima

Hi Udo
Interesting. do you have problems with the iris roots growing out the bottoms?
do you have the pots on a sand base or on greenhouse table or on a wire grid table?

i tried a few oncos in 4" (10cm) pots by 5" (13cm) deep and they did ok and i got a bloom or two but they did much better in later years when i removed the pots and just planted them in the sand plunge.

What do you do for summer dormancy?  i have mine outside in a sand bed in afternoon sun. but we got lots of thunderstorms sometime without any warning and i cannot always cover them. I don't have a greenhouse.

do you grow Iris camillae? any special culture?

Hi Wimmer,
the pots stand on dunes situation gravel directly on the surface of the earth. The patch is covered the whole year with a window. I do not have problem with root decay, importantly is absolutely enough air movement. From the middle of June till the end of September they completely dry.
Iris camillae I do not have yet in culture.

The named cultivar crosses would be harder to get into Oz. Some of the atropurpurea, haynei, urmiensis or stolonifera would be the easiest to get in and to try to germinate and grow Jamus.

Wow Otto it looks to be very well grown. Lucky you to have both.  PS I have a bud on Iris auranitica (ex embryo cultured by dear kind PeterG) - so much later than the rest which have finished.

Here is another seedling of JJA 600.600 (Iris urumiensis) emerging, after I learned that I was not correctly following the instructions for forced germination. (Thanks, Peter.)
I might point out that the "pointed end" of the seed, in some species, eg (I. barnumae) is the chalazal end, and if this is cut, nothing will ever happen. The micropylar end, ie with the aril, is the end that needs to be cut, into the endosperm and slicing off a tiny bit of the embryo itself. I didn't realize that it's the embryo itself that needs to be cut, and not just the endosperm.
So now I have a number of seeds germinating from Archibald collections. I'm telling them how much they'll like my garden, which I hope is encouraging to them.

Well done Pat ! You jade a successful season !
I also think your Iris lineolata is not a pure species :-)

About the picture of Iris urumiensis I posted. Before I lose whatever credibility I may have had in the past, I should note that this is the extremely rare variety struthionoides (ie, ostrich-like), which emerges root first.
In the turf industry here in the U.S. they have a basic instruction for people laying turf, "Green side up", which holds for irises too. The remainder of the seedlings are germinating in the normal manner.

Don't worry about your credibility, the option to grow upside down seems widespread in aril iris.    I grow quite a few from seed using embryo culture, carefully orienting the embryos root end down.   It makes no difference, about five percent turn over and grow the shoots downwards.   It doesn't seem to matter, in fact, they grow at least as well as those that grow the conventional way.   Eventually most see the error of their ways, but there are a lot that only get their leaves out of agar when planted out.    I used to open the tubes and reseat the plantlets in the "proper" orientation, but this doesn't really improve survival, so these days I just let them get on with it.   Hence the attached picture!
Still, glad to see the germination!

Thanks, though I believe I lost all credibility the first time I posted in the Galanthus section....
But never mind that. I was given a small amount of old seed to try to germinate, not realizing it came with instructions. The plants themselves grow quite readily in my climate.
Here is JCA 590.801, Iris lycotis, emerging green side up.

Agar culture looks interesting, and worthwhile, though of course one has to have seeds in the first place.

Example of what happens when you follow the instructions.... These are JCA 590.801 and 589.605.

(The irises will probably all die now that I posted a picture of them.)

Can someone please point me to "the instructions"? I have some seed of I. stolonifera I'd like to sow soon. Seeing all these pictures of healthy and successful germinations is making me impatient.

Link with good pictures showing what to do. http://www.srgc.net/forum/index.php?topic=6450.0 (http://www.srgc.net/forum/index.php?topic=6450.0)

The purpose of this type of forced germination is to remove the micropylar barrier which prevents the embryo from emerging. Nature does this, too, but takes forever to do it.
In essence, you are slicing off a tiny (1mm or less) portion of the root of the embryo.

Someone told me that oncocyclus iris seeds were readily available. I don't think that's true.
But I was given quite a bit of seed recently. It will be interesting to see if it's viable. Most of it was collected in the wild in the late 1960s to mid-1970s.
Soaking them right now.

Oh, well. After soaking the seed, I cut into seeds of several species, and they're not viable. Maybe forty-five years of storage was too much for them. I suppose if they had been frozen, different story.
You never know until you try.

Pity; great jars though (pepper pots?). Are they the same vintage?

Those are salt shakers, vintage 2013, from Amazon. Purchased expressly for soaking oncocyclus seeds. I figured after the disinfecting process, the shakers would make it easier to change the water daily, since I envisioned seeds going right down the drain with any other method.

Clever idea, Bob ... found the very item via Google, a US product.

About the only good idea to have emerged from yours truly in quite a while. ....
The strange thing, now, is that, with the ancient seeds having died, I returned to the first batch of seeds I received, and now the remaining seeds, from packets I just sowed last week and which are now germinating, are also dead.
I'm soaking the rest of the seeds from the first batch, seeds about five years old, just to make sure there isn't some force field around the house which is killing the seeds. Or a curse.
I do admit that I have the power to kill a plant just by looking at it.

Scary, Bob. It must be nice to have so much seed to kill.  ::)

It's not terrible, though I notice for the first time in a quarter century that I'm running out of pots. The BEF polypropylene Grower's Pots are the best I've ever used, and have been left outside for that many years.
Still, if anyone felt like sending me some dionysia seed, I'd find pots for them ....
That's one of the frustrating things about gardening over here; so many plants are difficult to impossible to acquire. I can get 3000 kinds of hostas or daylilies, though, if I wanted them.
