@evelyninthegarden I order seeds, about whenever the mood strikes me! I am awful about that Rolling my eyes. I ought to make a New Years resolution, against it, but I just have so many plants, I need to replace.!

I'm a seedaholic too (which happens to be another great seed vendor! Big Grin ) and I have a bit of advice:

Jelitto and Chiltern are both very good, but beware their catalogues as they are every bit as tempting as the iris variety!! (How do I know? Well, let me just say that my seedbox is a (rather large) breadbox nodding )
You don't know if it will grow until you try!

Oh geez, & I just read a pdf posted in the Rock Garden Forum, showing a photo of Iris acutiloba ssp. lineolata, from Iran. I WONDER WHO HAS SEEDS OF THAT ONE? Rolling my eyes.

@evelyninthegarden I think it is a brand new post from today. I just got a severe case of Oncocyclus envy & now want it, really badly, in the worst way. Then read that it can take over a year, to germinate. Anybody got any spare Euros? Drooling

@ShawnSteve ~ If you are interested in Regeliocyclus Iris Dardanus, here is the link:
https://www.vanengelen.com/flo...

They will be available next fall.

Are you interested in the Oncocyclus? Were you going to buy the rhizomes? Or seeds?

I read that those seeds can sometimes take up to 10 years to germinate.

@evelyninthegarden I just feel like exploring seed growing, of some Oncocyclus Iris seeds. We see the the flowers as making them so different, but even from different countries in Asia, , they are very closely related. I suspect, whatever is used to define a species, might not exactly apply, the same way as we think of many other plants. as opposed to Oncocyclus Iris. Apparently, although there is a great"diversity in what we see in the flowers", & these Iris grow on a "cline" then the chromosome 2n=20, basically amounts to the vast differences in space, doesn't exactly translate so much as to them being much different from one another. From what I read into it, I realize they just look differently & want to call then species.& from what I just read, about these, I want to attempt to try embryo rescue in Agar. It can't be too difficult. Just requiring keeping it very sanitized.

I used to order seeds from Thompson & Morgan, way back in the 1980's. People would often complain about "poor germination' with their seeds from them. I thought, "Well, if they think they are sowing seeds as if they are all Marigolds, then it's no wonder." I didn't have problems like that. I may join SIGNA & get some seeds eventually. I will simply attempt scarification at first & if that isn't working, attempt to extract the seed embryo & then keep it as sterile as possible. I'm not waiting ten years for a seed to sprout!

I also dream about Oncocuclus. today I have three Species of seeds. one in the ground, but nothing sprouted yet. and the other two stratify in the fridge...
if I have sprouted seeds, I can safely order them for you next season.
also wondering where you can buy them

@Serjio I don't know how well seeds get though the mail these days. Thank you for offering. Did you try to scarify, your seeds, besides stratification? Perhaps if you take a metal file, if necessary, or a wet stone, used to sharpen a knife, it may result in better germination. You do not use the knife. Instead, you carefully file away some of the seed coat with the knife sharpening stone to expose the seeds embryo
Carefully, slowly file away, just until the seed embryo is exposed, without damaging the seed embryo & it may work for better germination. You must also watch, to be sure you do not rot the seeds. Also, most seeds generally sprout, just at about the same time, as before the plant begins to start flowering. Also, if you know when it flowers, then that should also be when they want to germinate. best

Thank you! Yes, I have read about similar experiences promoting germination in Russian sources. But it's scary to do with such fragile seeds! But I'll still try it sometime if they don't sprout.. As for the mail, I successfully received a package with seeds from SIGNA seeds. I also sent the seeds to the US, they're still on the way. I can report back later on the results of this shipment. I came across a price list with oncocycle here: https://store.arilsociety.org (now this website maintenance). Do you know anything about this site? can I buy oncocycles there if I become a member of the community?

@Serjio Yes, I think it is possible, but they may have a website, meant just for Russia, too? But I went to what may have been the Home page of Aril International Society. The way to search may be, to use terms Aril Society International organization, they may be both the same & provides a link, to other member societies were shown such as for Chech, Italy, , Russia , etc..I have considered both the Aril Society but with the SIGNA, there are other plant seeds varieties, besides Aril Iris. I can't access the link provided, as my browser gives "Unsecure website" message & stops me. So maybe it is down, until seeds are offered to members, as when it is 'secure,'s & likely Paypal & Credit Cards info would get secured, when making purchases.
The cost shown for membership was shown at $17.& mentioned a discount for Australia & one other (English language? ) Country.The .org suffix to the website, may indicate non profit organization. I just awoke from a brief sleep, so I am not fully awake yet! But, if these are the same website or Society, then probably you may purchase seeds at least. I just don't know yet.. But a paid member, may answer your question better, than I can.
If any of your seeds have become swollen up, maybe they could use a little more warmth & not as cold, as outside.A frozen seed has to be above32F (0C?) to begin germination.Can you move some potted seeds from outside, to your lights?About this time, plants grown in a sunny window, would bloom about now. Closer to spring in mountains wild habitat& maybe those near warmer coastal areas of the middle East, between now & springtime.

@Serjio The Aril website, is joined under the American Iris Society, website. If you do bring any pots of your Iris species indoors, as they are frozen, when they thaw out ( defrost) they may become susceptible to getting mold, or fungus, especially if the growing medium has much organic matter in it. Or it may damage the embryo, but may possibly crack the seed coat & allow moisture to enter to the inner seed coat .It is best to slowly defrost them, perhaps in the refrigerator for a week. Some people pre-treat seeds with a weak solution of hydrogen peroxide, (3 to 5%) or low percentage of Sodium hypochlorite (bleach, added to water at about 5% solution strenght),- ( but not for very long ! ) as you don't want the seeds to absorb these chemicals, if they suddenly want to take up moisture & germinate. Perhaps rinse in lukewarm water first, then try to prevent any disease on the seeds. Frozen, or very cold growing medium, brought indoors needs time to adjust first, & some use the microwave to kill pathogens or diseases, before sowing their seeds.

Hi, Shawn!
Yes, I also had a warning when I opened the homepage of the Aril International society website. But I clicked "Continue anyway", but the site was empty, with a warning about technical work. A month ago it opened normally, without warning, and there was published the price for Arils and arilbreds for members of society. Did I understand correctly that it would no longer function independently and would work through the American Iris society website? I wish I'd tried the hydrogen peroxide method you described. What does it mean to freeze? cold storage (-18 C)? I stratify the seeds in the fridge at +5 C for a month. I hurriedly interrupted the stratification and threw them into the ground.after 4 weeks in the ground near the window (the temperature is about +22 C) sprouted seeds 4 species of iris 30. (Iris latifolia, Iris lactea, Iris domestica, Iris spuria subsp. halophila). Now I wonder what to do next. Continue to keep them warm, in the hope that they will germinate, or put them back together with the ground in the refrigerator (previously cut out of the seedling cassette cells with sprouted seedlings), or put in the garden (now we have snow and rain)..
we have no analogue of the exchange of the exchange of seeds of irises allow. Maybe in the future I can arrange that. In the Russian iris society this year offered for exchange only seeds of Siberian irises and irises ensata domestic selection. Therefore, while all hope for foreign sources.

@Serjio. Once a seed has sprouted then it should be kept at least above freezing. In my unexperienced opinion, if they are showing a radicle, then I would sow them in a pot and keep them under lights. I suppose that species from colder regions would need below room temperature ( around 20ยบC), perhaps they would do better in an area that is about 7ยบC/10ยบC ( an unheated entrance porch). I doubt that placing your seeds outside now will improve anything. Once germination has started then the soft tissues are much more prone to freezing damage. I hope this helps you in your choices.

Hello, Arturo. alas, I have no room where the temperature would be below room temperature. I meant one option, if you put in the garden those 26 types of seeds that are not sprouted. I so think that they have not yet activated and have not started the germination process. But I'm leaning more towards the fridge option. It has a positive temperature, possible sprouts will not die. I'll leave it there for another 2 months.

@serjio. That makes sense!. Actually the refrigerator is like a microscopic cold room and is above freezing. If the seeds are large enough they can be stratified just with some moist paper towel, inside a plastic bag. Thus it uses up little space. One option to reduce possibility of mold developing,is by dipping your seeds for a few minutes in weak bleach solution ( sodium hipochlorite) and also spray with that, the paper towel. (Weak solution is one part bleach 15 parts tap water).

before sowing these seeds, I lowered for a few hours in a solution with Phytosporin. now they with land in cassettes for seedlings of. I think that they will get together with the earth in the refrigerator Whistling
