R. dupontii/R. moschata nivea

This is a very interesting moschata x gallica cross…has anybody worked with this? Moschata’s remonant, you’d think crossing this with a repeater might restore remonancy?

It could become Damask 2.0

Is that a good or a bad thing?

Neither, I suppose. I have a seedling of Henry’s thats Hybrid Rugosa x Basye’s Amphidipploid. It behaves as a rambling shrub with that moschata or damask type of foliage. It has yet to bloom, mostly due to my neglect, but it may bloom next year, I believe. So the obvious issue is getting beyond that hurdle so that its more … reliable.

I have Robert’s Cardinal Hume X Autumn Damask which repeats here. It’s seedling # 1.

At least one Noisette expert has told me that ‘true’ noisettes (half china, half moschata) will take at least two years to bloom as seedlings.

From what I’ve seen, once such a seedling starts to bloom, it doesn’t stop.

R. dupontii is a top contender on my list to get for next spring. The list is still about 100 varieties long but the more I look into this one and the more I define my goals the more it looks like it will find a place here.

I wonder how similar to Autumn Damask you can get if you add a little R. fedtschenkoana pollen on it. Assuming of course it sets hips. It would be fun to try. Guess I better start looking for R. fed. now or at least some pollen? To me, it would be kind of interesting to get several plants out of the cross and just take note of the differences between all of them. Would they have many differences seeing how they wouldn’t (presumably) have as complex of a background as the modern roses do?

That is my plan with Fedtschenkoana and my hybrids of it with Secret Garden. Kim

Kim,

I’ll have to hit you up for some pollen (or a sucker) of R. fedtchenkoana in a year or two if I end up getting R. dupontii or something similar. I have a few of your DLFED crosses so I think a few of them might be worth putting on it too. I still don’t know which way to go with my hobby but it is getting clearer.

Wonder what a Buck cross would do with this one.

Hi Andre, the two I’m most impressed with so far are DLFED 3 and DLFED 4, the mossy one and the repeat flowering one. Fedtschenkoana is putting out a few suckers, but the only place I can grow it has a lot of gopher activity in soil which drains far too well and requires frequent watering. I also have three self seedlings I germinated from its seed this year, all with slightly varying plant scents. It’ll be quite interesting watching how these develop. Kim

Does anyone know about the winter hardiness of R. dupontii? I’m guessing with R. gallica in it it may be good enough for zone 5 but with R. moschata as the other parent I’m not sure. HMF just has it set at default.

I now have a plant of it from Pickering in my posession and I am debating about putting it into the ground right away or growing it in a nursery can for a year to see how it does during the winter (I’d bury most of the plant if it is in the pot but leave a branch or two exposed to see how the coldness affects it). I’d prefer to put it in the ground right away but will go this route if nobody knows how it does in the colder areas. Thanks

Hi Andre,

I saw a plant of R. Dupontii growing in a rosarian’s garden in the Shenandoah Valley in Keezletown, VA. I don’t know what the zone would be there but I would imagine a zn6. It is located near Harrisonburg, VA. It was doing well there. I believe it was thornless and had a lovely fragrance. Never forgot it.
