This listing includes a reference to the origins of Joyce Demits' "The Gift", dated 7 Nov 2007. The totle of the publication seems to have gone lost, however. Can someone identify the source?

I have had a search and although the reference wording (of the fire) is familiar to me, I cannot find where it is from.
I did find a little on ‘The Gift’ from James Delahanty’s A Survey of American Polyanthas 2 [created May 18, 2007] he kindly shared with me.
Chez Vibert’s message 4160 on March 1, 2005 from Fred Boutin also mentions ‘The Gift’.

Here is another reference to "The Gift" being the same as R. multiflora 'Nana'. 'Nana' seems to be more of an umbrella category than one single variety, given that it was often sold as 'fairy rose seeds'.
Does anyone have strong opinions about combining these two records?
From 'The Plantsman', April/May 1995, p. 24:
"Twenty of the Best Hardy Roses for Nurserymen Selling Roses in New Hampshire" by Mike Lowe
The following are ten of the best repeat-flowering roses. Keep in mind that most miniature and Rugosa roses are very hardy.
Rosa multiflora Nana ("The Gift"). Dwarf repeat non-climbing form of Rosa multiflora. Large clusters of 30-40 blooms of signal-white half-inch flowers from June until frost. As the numbers of flowers decreases in the fall, they are augmented by thousands of red hips. Bush three feet high, six feet wide.

Does anyone know if Rosa multiflora seed needs to be stratified first or can germinate without cold treatment?

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.

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

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.

They used to use colchicine solution on different plant seeds decades ago to try and induce mutations because it's very mutagenic.

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]

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

I like to cook my rice with saffron and lemon grass. Never got my DNA duplicated/doubled from those crocus-stamen ;-)
Still just only one Jay-Jay.

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.

This rose grew form a packet of Thompson and Morgan Rosa multiflora 'Garden Party' seed. Of the 15 or so plants I raised all the others were very pale pink or white singles and semi-doubles. This plant I gave to a friend has flowered a cherry red, if anything darker than the photograph shows. In all other respects it is identical to its siblings.

I love that :). I want to hybridize everything with rugosa. Lol. They're the only roses that bloom properly and grow well aside from knockouts. Hehe. I'm tacky like that.

Could anyone please tell me, what is the best way to take cuttings of this rose?
|
REPLY

Just in the normal manner. Probably a (small) pencil size cutting in mid-summer in acid soil. Water once and then keep dryish in shade. If this doesn't work for you, take autumn cuttings. I am sure with this one, you will have to plant the cutting - and stand back.

Thank you Patricia. Last year I grew several plants from the 'Garden Party' seed mix sold by Thompson and Morgan. They all flowered white or pale pink except one that I gave to a friend which I saw yesterday and it is a much darker cherry red colour, very attractive. I was going to try semi-ripe cuttings with a little bottom heat. I'll post a picture of it later.

Just last week I noted tiny plants in one bed. They were a R. multiflora nana offspring ('Rose Marsh') and I had dropped bits of prunings on the soil. They were ALL sprouting and rooting down. You and I seem to have the same sort of soil. You will have no problem, I am sure.
