Nearly end of February and no new topic?
Here a picture of one of my favourites I could take today - Iris bismarckiana
-
absolutely stunning Hans
-
You are the person to start the topic Hans ;)
One of the best species.
-
beautiful and also one of my favourites - please hand pollinate - many thanks in advance , Otto.
-
You're rught Hans.. not pictures yet, but I guess the season is late in their natural countries as they had no rain...
-
:o :o :o Absolutely stunning Hans .
Great plant . I have a smal seedling and start to dream now ......
-
Hans: Great! I would like to invite everyone to enter the AIS First International Virtual Iris Show, found on the American Iris Society's Iris Encyclopedia. The Aril Society international will be offering a prize for the best Aril Iris entry.

A brilliant start of the season Hans !! :o :o
-
Thanks for the comments - hope to see flowers from all the other growers soon!
You are the person to start the topic Hans ;)
;D - like I did several times the last years ;)
beautiful and also one of my favourites - please hand pollinate - many thanks in advance , Otto.
Thanks Otto, I will do my best, but as there are 3 more Onco species in flower actually you never can be sure.
-
I was wondering when the arils were going to start flowering in the north. Beautiful Hans.
-
Beautiful Hans!
I went today to see Iris atropurpurea in nature and I found two stunning yellow forms:
-
That is gorgeous Miriam. Too bad we can't get that first yellow
one into cultivation.

-
Lovely way to start the thread for this year, Hans!
Miriam, I've been seeing yellow atropurpurea photos from David Shahak on Facebook lately - quite amazing! I had no idea such a thing was to be found!
-
Miriam thanks for posting those beautiful photos of Iris atropurpurea.
-
Hans, What a wonderful way to start off a season!
Miriam, Iris atropurpurea in colours that are best seen, not read about.
Thank you both for sharing these treasures!
-
Thanks a lot Pat, Miriam, Tom and Peter!
Miriam the pictures and plants you show are really fabolous!! :o
-
Beautifful irises Miriam
Iris assadiana is in flower today, it is one of the smaller species in this section.
-
and Iris hieruchamensis from a few days ago.
-
Hans, Miriam and Oron, we can only dream about these oncos here. Thanks for posting.
-
The Middle East has some extremely beautiful species.
I like esp. the photos taken in their natural habitat.
-
Thank you Oron for showing us these rare beauties.
-
Thanks Pat, Cyril and Luc.
Here is another one opened today, it is I. haynei, dark form, from the southern part of the Golan Heights.

Beautifful irises Miriam
Iris assadiana is in flower today, it is one of the smaller species in this section.
I like that one Oron . Very nice !
-
Oron, your plants look very happy in their new place ;)
One day trip to the Negev desert: Iris mariae, Iris hieruchamensis in many variations and Iris atrofusca.
-
....
-
Stunning plants Miriam !
Thanks for taking us to the desert !
-
Incredible pictures of "impossible"garden plants, shown in nature and cultivated. Lost almost my breath.
Thanks for showing these beauties!
-
Just wonderful to see Miriam. Thank you.
-
Miriam this is the next best thing to being there, wonderful. Thanks
-
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 !
Miriam, you Iris mariae are perfect… much better than in a garden ;D
looking forward to seeing more soon.
-
Fabulous Pictures and plants Oron and Miriam!! :o
Here some pictures from spain:
Iris mariae
Iris damascena
Iris kirkwoodiihybrid
-
Thank you all :)
Pat, indeed some of them are seedlings of Iris mariae, but most of them are annual weeds.
Fred, this location of Iris mariae is just amazing! you must go there.
-
Miriam, Wow!. Those mariae are special!
Oron, great photos!
Hans, as always, wonderful photos of beautiful plants. In particular I was struck by what a dark variant of mariae you showed,
-
Fabulous stuff!
Thank you all so much for posting these wonderful pics!
cheers

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
-
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.
-
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!
-
Oron where are the photos of Iris damascena taken as they seem to be in lines.
Darren I remember waiting for my first aril to flower. It seemed to take weeks.
-
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...
-
This damascene is indeed a beauty. I take it it's not freeze-hardy?
-
Oron so pleased that you have found a suitable site to grow the arils now. Makes all the difference.
-
iris acutiloba ssp. lineolata from Nagorno-Karabach close to the border with Azerbaijan.
-
congratulations Oron!
Very beautiful Luc!
Iris sari is flowering in my garden for the first time. It is from seed I received from Rafa :D
-
Iris assadiana
-
All I can say Luc is that you seem to know the right people or the right places to source these rare plants. Beautiful as usual
-
All I can say Luc is that you seem to know the right people or the right places to source these rare plants. Beautiful as usual
Pat
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 :)
-
All I can say Luc is that you seem to know the right people or the right places to source these rare plants. Beautiful as usual
I know both.
We also have our problems with these plants. They are not easy at all.
-
Miriam your sari is a real beauty!
I just recommend you to watch your cats carefully as they might play on it and accidentally divide it into two plants... ;)
-
better late than never.. here are my first flowers
Iris mariae from 3 years old seedling :), Iris kirkwodiae tall form and a different form of Iris sari.. without cat.. until now ;D
more to come soon...
-
Those are sumptuous Fred.
-
Beautiful Fred. With cooler nights some of the aril seeds and crosses are starting to germinate :D
-
Very nice pictures, Fred and Luc.
Here my first flower in the greenhouse,
Iris kirkwoodiae calcerea

Great performance Fred. You have the right infrastructure.
-
What name suit this one best: iris camillae or iris shelkownikowii ?
-
Iris camilnikowii Luc ;D ;D ;D ;D
Very nice form,.. and well grown !
-
One from Turkey: iris paradoxa f. choschab
-
Another example from the camillae complex
-
Luc, very interesting Iris.
Here my first flower outside, only rain protection:
Iris sari
-
For the information of Onco growers in UK and EU States keep an eye on the next edition of The Rock Garden in July. A new advertiser will be in place whose Onco List will be available by email from August. I will remind you all on this thread.
-
Luc your paradoxa choschab is a stunner, how many years between seeds and first flower?
i sown 6 seeds in 2012, 2 only germinated and i' don't think i'll see flowers until 2-3 years.
-
Another example from the camillae complex
:o :o :o :o :o without words !!

-
An iris paradoxa from the surroundings of Lake Sevan in Armenia.
-
I don't like the onco-hybrids, but this one is not bad.
-
This plants I have agreed under the name Iris damascena, however, doubt has.
She is about 25 cm high.
Who can help?
-
magnificent Iris
-
Iris iberica ssp. iberica from Georgia.
-
Congratuliations Luc,
today with me is exactly the same irises in blossom, Iris iberica ssp.iberica.
In the second picture an Iris of a friend, grown from seed coll. in Turkey, like a paradoxa with false colour.
-
Looks like condor's wings, stunning plants
-
Great plants in this post :)
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
-
Another iris paradoxa now from the very south of Armenia near the Iranian border.
-
Two "easy" one's from Turkey : iris sprengeri and iris sari in one of the colourforms.
-
Iris lycotis
-
Nice one Luc ! Where is it from ?
Here are some more pics.
Iris Paradoxa dark form and dwarf form
[attach=1][attach=2]
Iris afghanica (well.. not an Onco :-) )
[attach=3]
Iris lycotis
[attach=4]
And Iris lineolata

Ooops ! I forgot Iris nigricans :-[
[attach=1]
-
Excellent, Fred! Especially nice to see I. afghanica and I. nigricans.
-
real nice pics, Luc and Fred.
here in flower,
Iris iberica ssp.iberica x schelkownikowii
-
Thank you Tom :-)
very nice hybrid Udo !
-
Many thanks, Fred.
Here two new flowers this sunday:
Iris kirkwoodii
Iris acutiloba ssp.lineolata ( received under ssp.acutiloba)
-
Hello Dirk. The acutiloba looks more like sprengeri to me.
John B
-
Hello Dirk. The acutiloba looks more like sprengeri to me.

John, many thanks.
It is certainty a Iris sprengeri.
-
Iris paradoxa f. choschab just opened this afternoon, a gift from Arthur.
-
The image that I posted yesterday was from the flower as it first opened, it has now fully developed in todays sun.
-
Nice image of this wonderful iris Melvyn!

It is the first blossom Iris sari of this form and more nicely than expected.

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,
SRGC member
Erika
-
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.
-
Thank you Luc and Peter

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

Sounds like the conditions we have except we have to put a raincover on the beds.

the `Queen of Onco` ;D in flower,
Iris gatesii

Beautiful oncos lately. Yet to have Iris gatesii to see its beauty.

one of the last this spring,
Iris polackii from Iran

Very nice plants again !
Udo, Iris polackii is very similar to Iris barnumae.. no easy to make a difference.
Ru, as always.. nice plants in nature ;-)

A quite marvelous range of variation in the Iris camillae flowers - I hope that this will show everyone - not just those interested in Iris - that such wide variation is possible in a wild species - something that is often overlooked, I think! :-X
-
Ruslan
Were the Iris camillae photographed in many locations? I like them all.
-
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.
Thank you for sharing!
-
I photographed Iris camillae in three losations (20-30 km apart).
-
Thank you all for your positive feedback! :)
-
I agree with the comments so far. Thanks Ruslan for showing these amazing variations in iris camillae.
-
Wow! :P
-
Iris paradoxa atrata (first-year plant, dealing with bad weather) and Iris barnumae urmiensis (two different clones, both made it through -4C freeze without noticeable damage; all other blooms in my garden wiped out).
-
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.
-
Hi all.
I'm a new member.
I grow 5 native (to Israel) Oncocyclus species.
I read with great interest the post on forced germination, and it made we want to join this group (although I can't see myself doing this).
As a starter, here's a picture of I. Atropurpurea from my garden.
Cheers.
-
Some more pictures:
I. Mariae (probably - not 100% sure).
I. Haynei
I. Lorteti
-
Here's one of Iris Bismarckiana, also from my garden.
Can anyone tell me if the yellow patches on the leaf are due to a virus?
Thanks.
-
Welcome to the SRGC Forum, Yaki - you will have seen that there are a great many Iris lovers here and a lot of useful information is exchanged.
It is a pleasure to see the photos of your Iris.
-

-
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.
-
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.
-
You seem to be growing the lowland species which are the ones that do well for me too. I. mariae I have lost over the years
-
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
-
the last flower this spring:
Iris paradoxa f.atrata 'Gem of Lori'

Hi Udo, do you grow your oncos in 4" plastic pots?
Thanks Rimmer
-
Hi Udo, do you grow your oncos in 4" plastic pots?
Thanks Rimmer
Hi Rimmer,
yes, my Onco-Iris grown in 15 cm plastic pots.
-
Hi Rimmer,
yes, my Onco-Iris grown in 15 cm plastic pots.
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.
-
Hi Rimmer,
I also prefer to grow them directly in the sand, to in the ground under cover.
Iris camillae is a good grower, and, as usual, keep it dry from may to october.
-
Some arils starting to bloom here. Mainly dark species hybrids. The rain and cold might be not that good for them though. Seems that it has been cold and wet for the last month. I was in London and Winchester for three weeks but came home a week ago.
-
Welcome to the south hemisphere blooming time :) ;D ;) and pictures :)
Everything (almost) is dry and yellow here !
-
David Nicholson has announced some new advertisers in the Journal - this one will be of particular interest in this thread I think
PlantWorld (Holland) is a small nursery specialising in Oncocyclus Irises and they will have a list available from August. Enquiries to:-
oncocyclus.iris@gmail.com
http://www.plantworld-holland.nl/index.html (http://www.plantworld-holland.nl/index.html)
-
The year is passing quickly. Already, the first onco species this year for me, Iris haynei from seed from David Shahak, 1986 and embryo cultured in 2012.
-
Beautiful Peter. The arils here have had to put up with frosts the last few mornings so aren't looking the best. Oh for some prolonged sunshine. At least we aren't in Canberra which is really cold the last week or more.
-
seems that south meets north ;D :)
Here is Iris paradoxa ssp. coshab blooming.... today in the greenhouse !!!
Season is crazy !

-
No arils to show as most of the flowering stems have been hit by Jack Frost. Hoping for better weather.
-
Pat sorry to hear that the frost impacted your Irises. There have been bad frosts all over the state and I'm hearing farmers complaining of major crop losses in some parts during my travels for work. We didn't experience the same severity of frost here so the garden hasn't been affected.
-
Seed from the ASI seed exchange 2006 has germinated finally. (It is the fuzzy leaf in the foreground)
The tag says: (pink MTB x tet. OG T-99-5) x sib
An OGB donated by Harald Mathes in Germany.
The second photo of a flower was slightly protected by a Genista seedling.
This cross should be open in a day or two.
-
Pat (Arillady) sent me some of her hybrids a few years ago.
The first to flower is this cross she made between Iris kirkwoodiae and Iris atropurpurea; hopefully I'll get a pic of the fully open flower tomorrow,
cheers
fermi
-
I will post photos tomorrow of quite a few arils which are flowering as we are still on limited download.
-
Missed out on getting a pic yesterday because of the rain and this morning the flower looked a bit battered :( but I got a couple of pics
Anyway another one of Pat's is about to open up as well! PT 0317
cheers
fermi
-
Love the colour of this cross - the tag has disappeared and I did not do a planting plan but I should imagine it is a 2009 cross.
PT0447
Iris mariae hybrid
PT0817
PT0918 - love this yellow

Pat,
those colours are superb!
Here's your PT0317 in flower bloom with another still to come.
cheers

Well grown Fermi.

Very nice, Pat and Fermi!

Two small oncocyclus
Iris acutiloba lineolata
Iris paradoxa ssp paradoxa x Iris kirkwoodii
Iris kirkwoodii var macropetala Embryo cultured by Peter Gras - the tallest onco I have ever grown.
-
Pat ,impressive clumps of Oncos in your garden of which I can only dream about in my temperate rain forest area .
I think your I. acutiloba v. lineolata could be a sari hybrid .
-
Very nice indeed, Pat. Glad to see success!
-
Otto I thought I might make a big blue with identifcations again this season. I probably forgot to change the label last year. At least sari likes it here!!
-
Beautiful irises Pat. I'm freaking out over the seedlist on the ASI webpage, trying to decide what I ought to start with considering I know very little about these Irises as yet.
-
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.

Thanks to Peter Gras ,who embryo cultured those seeds of I. sofarana ssp. kasruwana from Archibald ( ex Wallis collection in Lebanon ) I can enjoy this bloom today . I think Kew regards it as a synonym of I. susiana . I am lucky to have one of the original copies of Curtis's Bot. Mag. from 1788 with handcoloured copper plates , so here is the page .

Lovely Otto, both the painting and your Iris.

Absolutely magnificent Otto. These irises are one of the natural wonders of the plant world, it's a credit to you that you have one flowering there, especially considering the less than conducive climatic conditions where you are. I wish i lived closer to you, I'd rush over with my camera and force it to pose for me. :)
-
Otto a stunning Iris.
-
Beautiful.
I assume this is 0597950. One seed of this collection germinated here last week. (I do things the hard way.)

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.
