I hear that Thomas for Roses aren't accepting orders at present for next year, due to ill-health and advancing age.
If the nursery is to close, it will be a great loss to heritage roses in Australia; they have a remarkable collection, especially of 1920s-1940s roses. And a lovely display garden.

That is sad. They've been my go to for the past two seasons. Between them and mistydowns theres a lot that will become unavailable :/

Still flowering quite decently now in the middle of an Australian winter (so not that cold), have had two slight freezes (enough to see a slight ice covering over lawns and kill the foliage of intolerant plants like Mirabilis jalapa) but MC has been unphased. Is still with it's glossy dark leaves unlike almost every other rose in my garden. Biggest downside is aphids are very attracted to the plant (but that's a fairly common flaw).

This rose is beautiful. It's newer but there aren't any sources or gardens listed. Is it/was it ever available in commerce?

Millington's roses cannot be imported into the USA on account of some rose disease unknown to science. One wonders how anyone manages to grow roses at all in Oz.

Illicit narcotics pass through our borders with ease but God help the person who tries to import roses.

Bwahaha! Ain't it the truth. And because roses aren't 'important' enough, no one will ever do the research to show the USDA is out of their minds on this one. We can always hope, I suppose. If it got imported into Europe, and then someone tried to import it to the US, would it get hit with the same ban? Not that this would help any of us. I'm going to have to research this now.
I do hope it's available in Australia at least.

As far as I understand it, Warren's roses are mostly being released in Belgium, not Oz, because the big rose nurseries in Oz are still focussed on high-centred HTs.

Which is funny (not haha) in that most of the population live in the major cities who's suburbs are being turned from 1/4 acre blocks into townhouse and granny flat estates, garden space is becoming much smaller than it was. It'll be interesting to see what happens in the next 10 to 20 years as the boomer generation decline and with space and desire to garden being lower in younger generations.

With difficulty if at all, I am afraid. Some years ago Vintage Gardens imported some rare cultivars from a famous rose garden in Italy--Italy it seems is also host to the dreaded disease--by way of a devious roundabout TInker to Evers to Chance route from Italy to another European country and from there to I believe the SF airport. Filroses regrets on its' website that it can no longer export to the USA and there were recounted on the gardenweb forum horror stories of roses from Europe being held up in customs till they died.

It is enough to make one consider deals with the devil, trips to Europe and special shipments to a confederate stateside, etc.

That's crazy. I wonder how this 'disease' came into being, and why they're so fixated on it. If they think it's so terrible it must affect other crops, and you'd think there'd be some research into it.

I think back in the day, when Jackson & Perkins was a successful and profitable company, it teamed up with Weeks and maybe others and bought a congressperson. Roses being a small crop, it would have been fairly easy to get import restrictions into a farm bill. The alleged disease was called lettuce wilt or something of the sort, as I recall. What lettuce might have to do with roses I cannot say.

Don't we wish. When one is dealing with the US Congress, money talks. Now, if everyone overseas who would like to import roses into the USA got together and put up some cash...maybe something could happen.

Does anyone know if Rosa multiflora seed needs to be stratified first or can germinate without cold treatment?
REPLY
Reply #1 of 23 posted 17 DEC by jedmar
Rosa multiflora grows in 300-2000m in China, so it would seem to need cold periods. In USA it is an invasive neophyte in a band from Kentucky to the East Coast. I found this text on Bugwood Wiki:
"In eastern North America, multiflora rose is abundant from the Great Plains (where the species has been planted as wind breaks) to the east coast. It occurs from northern Texas, Arkansas, Mississippi, Alabama, and Georgia in the south, north to the New England coast, central New York, southern Michigan, Wisconsin, and Minnesota. It occurs only as plantings south of central Georgia, probably because of the lack of cold temperatures needed to stimulate seed germination. The plant’s northern distribution is limited by its sensitivity to severe cold temperatures."

Thank you Jedmar, the seeds are now in my refrigerator. The seeds are from a particularly deep pink flowered variety of the above dwarf sport.

When I was in Switzerland, some years ago, on the train from Zurich to Kreuzlingen there were white rambler type roses growing wild on the embankments, sprawling on the ground. Would that have been multiflora?
REPLY
Reply #4 of 23 posted 17 DEC by jedmar
I must admit I have no idea! Rosa multiflora is not an invasive neophyte in Switzerland. Could it have been plantings of Rosa rugosa alba?
REPLY
Reply #5 of 23 posted 17 DEC by Andrew from Dolton
No, it definitely had stems trailing on the ground and panicles of smallish flowers, maybe too prostrate to be multiflora.

Reply #6 of 23 posted 8 JAN by Andrew from Dolton
I put the seeds in the refrigerator for three weeks, then, because I am impatient and they had already been outside in the cold I took them out and gave them some bottom heat on new year's day. This morning the first seedling has germinated.

Would that implicate, that seeds of a lot of roses don't need stratification to germinate.
I already wondered, whether Hybrid Tea seeds would be better of without a cool period.
REPLY
Reply #8 of 23 posted 8 JAN by Andrew from Dolton
What I had planned to do was to alternate between cold and warmth periods, 30 days each time, until the seed germinated. I picked the seed the day before I sowed them (on 15th December), and before that we had had six weeks of temperatures cool enough to stratify seed. They actually probably didn't need any time in the fridge at all. I would think that Hybrid-Tea roses would just grow straight away from a hip picked from outside right now, but I wouldn't be so sure about seed collected say in September. A China rose or a Tea probably don't need a cold period because they come from a warmer climate.

Next week the seeds I got from Pakistan of R. webbiana collected from Batura Glacier, Gilgit Baltistan region, Pakistan by KBW Organic 9b will be sown.
Then they have been in the fridge at 1°C for two months. I think, that those need stratification, when I see at which height they were collected near a glacier.

Reply #10 of 23 posted 8 JAN by Andrew from Dolton
Yes I think that's wise. Sowing seeds and waiting for them to germinate is just the most exciting thing
REPLY
Reply #11 of 23 posted 8 JAN by Jay-Jay
I hope they'll germinate, for I got them dried. Soaked them for 48 hours in regularly replenished water, kept them a short period in a watery solution of Hydrogen-peroxide and per-acetic acid, to kill eventual diseases.
And then kept them in the fridge in wet coarse grained sand.

HT, floribunda and mini's in my experience will germinate in around 2 weeks if temps are below ~15c/59f above that and nope nothing happens. I don't stratify seed (intentionally, winter night temps that can reach fridge temps though), I just sow directly into pots outside the beginning of autumn, march (summer hemisphere, sydney australia here) was super warm this year so germination didn't happen until mid april (when temps started being under 15c/59f) unlike previous years when they normally start around 2 weeks after sowing.

It's not just those classes either, I have around 150 seedlings from Lord Penzance at the moment, they were some of the earliest to germinate and never saw temps of 10c/50f let alone what a fridge would be and yet still seems to be around 75% germination rate (Others have said R. rubignosa seed wouldn't germinate until the second year....I really wasn't expect so many seedlings). Have Dagmar Hastrup seedlings too but it could be argued that they didn't start germinating until night time temps reached almost fridge level for a couple hours at night.

Thank You Plazbo.
I'll wait and see what happens next year(s).
I meant, I became those seeds dried... But hope that customs / import-bureau didn't gamma-ray them whether in Pakistan, or in The Netherlands.

They use to try and force mutations with that sort of thing (x-ray seeds) I forget, I think there was some success with it....so even if they did you might end up with something unique. Granted most mutations are usually not visually pleasant but I'll cross my fingers for you any way.

Reply #15 of 23 posted 26 JUN by HubertG
They used to use colchicine solution on different plant seeds decades ago to try and induce mutations because it's very mutagenic.
REPLY
Reply #16 of 23 posted 26 JUN by Jay-Jay
Colchicine was used to get double as big pigs, they became bigger (2n) but were sterile. Colchicine was extracted from Herfsttijloos (Dutch) [ he autumn crocus ; the jonquil ; the (common) meadow saffron]

Jay-Jay, that's why I avoid eating anything with saffron in it!

Hubert,
Saffron is from another, totally different, plantspecies. Saffron is from Crocus sativus and colchicine is extracted from Colchicum autumnale.

I once got seeds from tomatoes, that were exposed to radiation on a space-mission. I was told, that it was an experiment from schoolchildren. The color of that tomato was weird, but that particular tomato is nowadays commonly available in supermarkets.
