This garden needs sorting out.
First, it is in the District of Columbia for which there is no choice on the dropdown menus to designate the location for search. Second, the garden's website is apparently defunct - nationalgarden.org. Third, J&P apparently donated a bundle to establish either a successor alternative garden now at the USBG named the Margaret Hagedorn Rose Garden.

The current URL for this garden is https://www.usbg.gov/national-garden. It has very little information on the rose garden, other than it specializes in roses that can be grown in the Middle Atlantic states using organic methods. Among the roses growing there are Autumn Damask, banksiae, Cramoisi Superior and Duchesse de Brabant. Some nice moderns, as well. The garden is well worth a visit.

I'm torn with my feelings for this rose. On the positive side, the flowers are gorgeous, generous and long-lasting (they lasted on the plant for more than five days!). The fragrance is wonderful. On the negative side, this is one of the only two roses in my Zone 6a garden that got blackspot this fall, the other being floribunda rose Moondance. It didn't seem to weaken the plant, but even after spraying it couldn't seem to shake it.
We've had one of our rainiest summers on record in the Northeast this year. I'm hoping that next year if I start spraying early I can fend off the blackspot. Julia Child is a truly remarkable flower, and it's a pity that it seems more susceptible than the other roses.

Large blossomed, double petaled, stable yellow roses hardy to zone 5 are tough to come by. Rigorous spraying with Bayer kept mine clean this season but it seems also to hold some broad disease resistance of its own so I have been using it in my breeding program pretty heavily. If I were you I'd plant a few more bushes of it.

Thanks for the advice! I admit that I'm new to growing roses, but Julia Child is probably the most beautiful flower I've seen. I had been thinking that I should plant a few more. Even with the blackspot issues I've been having, you can't go wrong with a big, gorgeous flower that holds its petals for almost a week!

At the rose park of over 1,000 bushes - Singing-in-the-Rain floribunda beats Julia Child in non-stop, tons of bloom. The color is not washed out like Julia Child. Singing-in-the-Rain is in the Black-spot resistant list, with a refreshing musk scent.

Thanks, but where can you buy Singing-in-the-Rain?

Singing-in-the-rain is offered at Roses Unlimited as own-root. Tthe most disease-resistant yellow that doesn't fade is Honey Bouquet, surpasses Jullia Child in being compact, blooms don't fade, and great honey/musk scent. Honey Bouquet starts out as perfect HT exhibition form, then opens to ruffles with many petals in cool weather. Many people from different climates, including me, like Honey Bouquet.

Regan Nursery sell Singin' in the Rain as bare root. I have never understood the intense craze over Julia Childs for the rose only. But as a landscape bush in the right setting I can see how it would be great. But it will not be the yellow for my yard. I have heard so many that say Honey Bouquet is the one to get, and I may just end up with it.

What you can expect of Prairie Peace seedlings:
Genotypes: WS127, WS132, WS135, WS136, WS137,WS138, WS140, WS205, WS204.
WS140 has rebloomed in summer of 2014.
.
.
There is another seedling of open pollinated Prairie Peace. It was raised by Douglas Wild from Canada and has the number 'DW101F1'. Doug described its habit like this: "Attached are two photos of one seedling (PRP X OP) that has impressed me with it's rebloom characteristics...typically in late summer, this seedling has dark hips (1st bloom cycle), green hips (2nd bloom cycle), and flower (3rd bloom cycle) all on the same plant. It also has numerous blooms along the upper canes." and "I think it would be fair to say it can have 3 bloom cycles per year under ideal conditions".
"this plant is over two meters in height...very vigorous"
Surely one nice rose with great characteristics.

Fascinating. Are these OP?

Yes they are OP.
I hope it helps sometime somebody.
My Thanks to Margit Schowalter who provided the seeds.

Since they are likely self pollinated It would be interesting to see if they offered improved fertility over the seed parent.

As far as I know Prairie Peace is fertile. The problem with PP seeds seems to be that the seeds do not germinate naturally due to a too hard seedcoat. All my seedlings were germinated by Don Holman's embryo rescue method, but all embryos were viable, I had a very high success rate.

WS140 gave me 2 OP seedlings that germinated naturally, so it seems not to have the seedcoat problem.

In spring 2015 I got 4 seedlings of 230 seeds sown in a pot an placed outside, so spontaneos germination is also not very good.

It would be very interesting to learn more about your seedlings, such as rebloom capacity, fragrance and shape and size of the bushes. Would be most interested in a cutting from a good one. Good luck with it all!

unfortunately there is not that much more that i can tell you. All of them are healthy plants, size up to now is 1m to 1,5m but they might grow bigger still if they get time and space. Shape is difficult to tell as all are growing in confined space, the stick all to the spinosiisima type, some are more branching in the upper canes some less. Sorry I did´nt care for the fragrance so far. Regarding cuttings you might contact me via pm. You know Prairie Peace is available now in Europe?

Many thanks! Yes, I noticed Rosenposten has it but am actually more interested in a more yellow, pink or yellow-pink variety with similar qualities. Some of your varieties looked more in that direction. If possible, we could arrange with a cutting next year (via PM).
