Joe,
How is Ruglauca making out up your way?
Rob
Rob- It’s doing ok! A blossom here and there. Same with R#3 growing next to it. I don’t have any disease pressure in that area yet, so we can’t test for spot resistance yet.
Theodesia- Doesn’t it just seem like Kim’s Murphy’s Law of breeding roses holds special sway with fragrance? I raise some very fragrant roses, but I can’t think of any super fragrant seedlings yet.
Regarding Hansa… mine was covered with blooms this spring and has set nary a hip.
Regarding other rugosa hybrids… I have some hip set on Belle Poitevine with Hazeldean, and one hip with Oso Easy Lemon Zest. Noticing a lot of variation with my Henry Hudson OP’s this spring, I set out a bunch of potted roses near HH as it was approaching the end of it’s first flush. There seem to be more OP hips this year. I love the variation of the OP seedlings…some seem quite non-rugose.
Several “Belle Poitevine x unlabeled” seedlings are showing juvenile remontancy. It’s pretty exciting to me that the repeat flowering characteristic of rugosas can be passed on in crosses with more modern roses. I’m hoping the rugosa hardiness has a strong influence on the seedlings.
Joe,
You should start getting more blooms next season. Mine waited until season 3 before putting out plenty of blooms. Here in BS central (Mid-atlantic states) I have not a spot on Ruglauca. I did get some Sequoia Ruby x Ruglauca seedlings from last season and most have bloomed. A few interesting…
Rob,
Here’s a current picture of my Ruglauca. R#3 is growing next to her and is a similar size. Have you had any hip set on Ruglauca?
(sorry, everyone, to be veering off the topic of this thread)

Joe,
Not many hips but looks good as a pollen parent. I had one Ruglauca x Strawberry Cream and a few OP seedlings.
Rob
The only surviving Country Dancer x Hansa had a first bloom (pictured above) that was a very ordinary off white or cream. I would have probably culled it immediately, because it had an early bout with mildew (no black spot), from which it now seems to be recovering. However, the second bloom seems quite different than the first. As it matures, it has what I would call a soft apricot tinge. Maybe I will wait before sending this one off…

After reading this topic, I decided to look more closely at making controlled crosses using Hansa. One did well crossed with Rosa woodsii and the other surprised me. Out of four crosses I got three very large hips of (Hansa X Prairie Dawn OP). the Prairie Dawn seedling is likely diploid but resembles the parent in all but size of the flowers and the number of petals. It is also like its parent being blackspot prone. This is one of those why not crosses that I am glad I made.
I know that it is early to say what the seedlings may be like if they do germinate.
This is Hansa x Country Dancer now in its second season. It bloomed very late in its first year with a very double pale apricot bloom with no scent, at least that I could detect. It was the only surviving member of that particular cross. I had hoped the first year bloom meant rebloom. However, it is July 5 and still no sign of bloom this year. Unlike any of the other crosses I’ve made with Hansa, it does not have rugosa-type foliage. In fact, it shiny, and the leaves are mainly trifoliate foliage, like a juvenile seedling. The new growth has a distinct blue tinge (I’m not sure where that came from). It is very slow growing, because thus far, it makes a blind shoot every few inches and then branches. I planted several hundred open-pollinated Hansa this year, from a relatively isolated plant, the nearest other rose was a Double Knockout. All seedlings have rugose foliage, most are weak and spindly, and none show any sign of first year bloom.
This year I went all out with Ames 5 on Hansa. I have started only in the past few days so I can’t comment yet. The reason for using this plant is only height, rebloom and yes hardyness. The two parents of ames5 Rosa multiflora height and heavy blooming and Rosa blanda for hardyness and acting as a bridge to multiflora genes. I also tried using Rosa multiflora on a hydrid rugosa/blanda parent that is an F2 -Used for to comfirm that pogeny are carriers of the rebloom gene.
More than just climbing as an ambition, I find the most beautiful smell comes from multiflora and some of its hybrids like Ames 5. I think what I am ambitious for is a tall large flowered Tea like Lady Hillingdon only hardy…and healthy.
Overall this cross is just stab in the dark. I am doing hopefully much more productive crosses so called bread and butter.

Best of luck, Johannes. It would be awesome to bridge the rugosa/multiflora gap and move forward.
An update, not being at the farm my mother had a look and the Hansa x Ames5 has 15ish large hips but what surprised me the crosses of Cassiorhodon hybrids (mentioned in a previous links) rugosa/ blanda/ Martin Frobisher formed hips with pure Rosa multiflora. Rosa blanda can do some wonderful things.
johannes
by johannes p, Rosa blanda can do some wonderful things
Blanda’s ability to act as a bridge is probably worthy of it’s own thread, but I have to agree with Johannes. I’ve yet to grow this species but just looking at it’s descendants on HMF has me pining for this rose. I think it deserves to be used more widely.
And to bring things slightly back to topic, I should say I’m happy to see this thread. Hansa is another rose that deserves more attention.
It’s nice to see that a few people here are working with it.
