Does anyone know if Rosa multiflora seed needs to be stratified first or can germinate without cold treatment?
Reply #1 of 12 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?

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?

No, it definitely had stems trailing on the ground and panicles of smallish flowers, maybe too prostrate to be multiflora.

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 #8 of 12 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.

Yes I think that's wise. Sowing seeds and waiting for them to germinate is just the most exciting thing
Reply #11 of 12 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.

My own root Sharifa is doing fantastic here in Western Washington. My soil is rocky and drains fast so I need to water often. This rose is in partial shade and has a lovely strong perfume.
Reply #1 of 1 posted 3 days ago by Jay-Jay
I would like to exaggerate: A very strong, good, but a bit soapy perfume.

Alas, this rose is no more due to poor green-management of the city and the people that do the job.
It was whacked in full bloom, just like its companions (2X Berberis verruculosa and a thornless Multiflora seedling the latter blooming too as in: ).
Reply #1 of 10 posted 13 days ago by Andrew from Dolton
How destructive, what a waste, very sad! Ignorant.
Reply #2 of 10 posted 13 days ago by Jay-Jay
Thanks Andrew, for the "Heads-Up".
And it was very obviously our plot:

You have photograhed that rose many times over the years and must have loved it well. What I don't understand is that it was in full bloom. My sympathies Jay-Jay.
It is difficult with ever-changing council people. You can tell one bloke, but then new dimwit employees come along and start whacking. Years ago Pat Toolan in South Australia had the same experience with a whole row of old roses on a roadside and many of them could not be saved. She started jumping up and down to the council and made such an impact that these days she oversees a garden for old roses on Council land which she helped to make (see The Barossa Old Rose Repository). As well, she managed to get the Council to help rescue an old 'Lady Hillingdon' and replant it almost outside the Council's front door. That does take a special sort of person, but education seems to be the key. Perhaps asking them to let you know of any old rose (you would have to keep at it) so that you may rescue it beforehand, might instill an awareness in council employees that roses are special.

Hi Patricia,
Thank You too. I'll take a look at the garden, You mention. But alas this city doesn't cherish its roses: Ground covering rose-beds in full bloom are flail-mown and a bed of Topaz Jewel, that I photographed in the past has disappeared completely, like more rose-beds did in exchange for short-mown grass....
And they are not at all interested in (or open minded for) criticism or free advise.

It was a nitwit as for knowledge of plants and a bit disabled as for intelligence, that performed the "PRUNING" as he mentioned it... and HE apologized for that and explained his motivation for his deed. It was the second time, that that person whacked things on our plot to almost ground-level. That time it was the complete Berberis verruculosa hedge.
But the one, who should have attended and guided him, did not quite understand the fuzz that I made and my sorrow. He only was interested in meters, that ought to be cleared from "green mess".
They will ask the insurance to compensate... But under a big oak, it will take years, before it will look like something again... That was the second damage this year in our garden, caused by the city.

But there are worse things to experience... And this might create new opportunities.
PS: The Westerlands' offspring is thriving and this year even very double-ones are starting to bloom.
And yes, soon I'll rustle (part of) a yellow Spinosissima seedling. (10x8m)

BTW Jay-Jay, I am getting untold pleasure from 'Erinnerung an Brod' which is largely down to your enthusiasm that I bought this rose. The best 50 euros I ever spent, Thank you.
Reply #6 of 10 posted 12 days ago by Jay-Jay
€ 50!!! Wow what a price... but rewarding, I read. This year it was just a short period of bloom, because of the high temps and dry weather.
Reply #7 of 10 posted 12 days ago by Andrew from Dolton
Yes, €50, indeed, wow. I had to buy it from Germany and do a money transfer at my bank. I have to say my experience of it being over quickly differs from yours. The first flowers started opening about two weeks ago and there is still two thirds left to flower. The first few flowers were proliferated and I was worried they would all be, 'Variegata di Bologna' was the same and 'Russelliana' was very bad as well. It has been very hot and dry here. We have not had any proper rain for almost a month and temperatures as high as 25C. Some of the roses are gone in two days but 'Erinnerung an Brod' lasts almost a week. I am extremely pleased with this rose.

My sympathies too Jay-Jay. So sad to lose these beautiful plants. It beggars belief that others are blind to the value of things.

Looks like Remember Me is somewhere in the background of this rose!
Reply #1 of 4 posted 23 OCT 14 by Michael Garhart
I know the breeder uses/used a lot of Singin' in the Rain and Remember Me in their breeding, so it wouldn't be too far of a leap to say this one is likely related to both.
Reply #2 of 4 posted 26 JUN 16 by Jay-Jay
It's almost a look-alike of Rhosyn Margaret Williams. Same parentage?
Reply #3 of 4 posted 12 JUL 16 by Michael Garhart
Possibly, yeah. I could tell you more, but the business I ordered this from this spring sent me..... Easy Does It. They also sent me a dead 'Claret', but promised to replace it next year *sigh*

Helpful, lol.

Don't worry, HMF! Not naming names!

Finally growing this rose. It's not much of a floribunda. Similar dimensions to my Gold Struck, so far. So grandiflora size for North America.

Looks like it is bred from Belle Epoque, which is blooming 10' away from Ann Henderson in my garden. Very similar plant traits. AH is much deeper in color and tighter in the bud, and only somewhat smaller blooms.
