Has anyone tried cross pollinating Rugosa, since it abundantly sets hips and creates seed pods. I was very interested in hearing what roses you were able to create from the attempt? I will be trying my hand at cross pollination this year..

There are lots of rugosa descendants listed. You have to be quick to prevent the rugosa self-pollinating.
It's prudent to assume that rugosa seedlings, like their parents, will sucker (sometimes aggressively) if grown on their own roots.

Plisa, the only rugosa I ever grew was 'Blanc Double de Courbet', and it didn't set hips, so don't try to use that as a seed parent. It has a beautiful fragrance though.

'Blanc double de Coubert' sets loads of hips.

I am new to Rugosa variety. I now have a new hedge of them and am wanting advice. We dug them up from another site and transplanted them in our yard. The sun is good and there has been a good amount of rain on the soil. The plants are 3-5 years old and about 3 1/2 feet tall. We tried to keep as much original dirt on the roses as possible but mostly they were bare root when they went into the ground. We put leaf mulch in the holes before covering them over and now water them a few times a day. We planted them this past Sunday and it is now Friday. A few stalks still have green leaves but the rest are turning dryish and brown.
Enough backstory, my question is, since it is the fall should we prune the roses to 6 inch stalks to try to help out the root system? Or will this additional trauma totally kill the plants? Any other suggestions to help them get over the move?

My white and pink Rugosa, is flowering abundantly for the first time in 3 years. It flowered last year too but it was a few flowers here and there. It was gone before I could get a good look at it. It was pruned gently for shaping in early fall, and seems to be flowering off of the old growth. The fragrance is beyond amazing and so is the pure white and magenta color of the flower(have both the white and the pink /magenta/purplish hard to come up with a color description-very rich shade). I wouldn't prune the old growth out yet.

I say about this rose what Graham Thomas used to say about Mme. Hardy: It's still the most beautiful white rose in existence. And unlike Mme. Hardy (which I also love), it appears to repeat well, it has a gorgeous change of foliage color in fall, and it'll feed its owner instead of the other way around (the hips are huge and tasty). :)

I don't own one--have just seen them various places.
That's made4 me want one (or many!), so I've put myself on the "want cuttings" list. I'd also be glad to get seeds, and would of course pay postage.

Graham Thomas' remark about R. rugosa alba notes that it is unusual among roses because the white of the flowers is pure. That's so true! There is no hint at all of any other color. The white is not chalky, milky, ivory, or peachy. It is PURE white.

Yep. I find that stunning. And the hips, the leaves, and the summer _and_ fall leaf colors are stunning.

Mine sometimes has a tinge of pink.

Re: R. rugosa alba. Bred (before 1850) by Unknown.

Both Rosenlexikon and Brent C. Dickerson's 'Old Roses: The Master List' 2nd edition, 2007, page 24 put this rose as being bred by Thunberg in 1784.

I believe Carl Peter Thunberg did not breed any roses, but he described species in his "Flora Japonica" (1784) (in Latin, unfortunately). The R. rugosa varieties had been available in Japan for many hundred years before.

Thank you for that. I was a good little girl and always respected my elders.
I will be looking at my R. rugosa alba with more respectful eyes.

If we had a Japanese correspondent, we might learn more about rose history - same for China. I am sure there is older artwork which could be very enlightening.

My guess is that R. rugosa alba is a naturally occurring variant of the species, a white-flowered natural variant.
Reply #5 of 5 posted 12 JUL 09 by Cass
That's my guess as well. The petal color of Rosa rugosa is described as purple-red, dark pink, or white by Flora of China.
