HAVE: R. setigera 'Serena'

If anyone in the US would like some R. setigera 'Serena' - I have plenty of rootlets, some much more than rootlets, for postage or if you have anything interesting you'd like to share, I might be game for a trade too.

Re: Experience with Great Maidens Blush?

http://www.roses.shoutwiki.com/wiki/Kategorie:Sievers Hallo Rolf, I'm quite surprised by the purity of yellow you were able to achieve with Yellow Blush: Small Maiden's Blush x Golden Giant as listed on the wiki.

Re: For Love of Roses

About two weeks before the OP on this thread, I had placed an order through their online system (which at least at that time was still able to accept orders - unsure of current status). I received an acknowledgement (auto-generated) and my card was charged. When I didn't hear back about a shipping t...

Re: 'Commander Gillette' X "3/4 Native"

Add mildew to some setigera. Those from David Z, at the U of MN arboretum location didn't mildew, but my line which derived from one at K-State, acquired decades ago, mildewed itself maybe to death after overwintering as rooted cuttings while the others stayed clean. I guess the same will be true o...

Re: 'Commander Gillette' X "3/4 Native"

Species? No sir. Rugosa rusts. Minutifolia and Stellata mirifica don't rust. They go dormant in dry and don't need to shut down for cold, or the dry shuts them down. Nutkana, Woodsii, Carolina, Virginiana and all the others I've messed with, rust. Oh, Serafinii, Californica and Spithamea haven't ru...

Re: Suitability question

Souvenir de la Malmaison has been a successful pollen parent to some nice offspring. Gertrude Jekyll was not a successful parent for David Austin, its creator, so I imagine it probably would not be for others. The others of his creation are a bit too new to know how they would be as parents.

Re: Varying Germination with Differing Pollen Parents

John Cook, who gave us 'Radiance', acted on this principle. In 1905 he wrote, "As the pollen sometimes is very scarce, it is better to put it only on two, or three pistils, repeating the operation the following day." And in 1906 commented, "It took twenty flowers of the Marechal Niel to produce eno...

Re: Varying Germination with Differing Pollen Parents

The saga of Darlow's Enigma continues. I don't know if you've read the posts from earlier this winter in which I bemoaned my low germ percentages from DE. Jim was kind enough to send me some open pollinated hips from his plant, and I was hoping that I'd have better luck because maybe mine had been ...

Re: Varying Germination with Differing Pollen Parents

I cannot speak as to why, but I had read that mutabilis pollen is frequently quite cooperative, and often can be used to pollinate some otherwise unwilling mothers. I have some setigera x mutabilis seedlings growing now, but R.setigera is usually selective of other synstyllae, reportedly. I was abl...

Re: Varying Germination with Differing Pollen Parents

How many seeds did you get per hip? Larry & Karl - Thanks for your responses. Apparently Darlow's Enigma is not a prodigious producer of seeds per hip, but does set very small hips easily. Generally I could depend on about ~4 seeds per hip and the general count was not different between Mutabilis, ...

Varying Germination with Differing Pollen Parents

Hello all, Last season I pollinated Darlow's Enigma with various parents and have experienced quite divergent germination rates. Does anyone have any thoughts as to what influence pollen parents have on germination might be? Here is a sampling of pollinations and corresponding results: x Mutabilis -...

Re: Fritz Nobis

Confirmed, the rose is John Grooms, introduced 1993 by Peter Beales, parentage is Fritz Nobis x Compassion. I've put in a comment with HMF - hopefully they will update the parentage info.

Re: Fritz Nobis

Dane,

I was reading in Peter Beales' book Classic Roses last night and apparently he raised a plant from it and introduced it to commerce. I'll have to take another look for the name. I do recall that FN was the female parent.

Re: Under-utilized species you feel might have merit

Three species I am intrigued with and don't know much about are R. blanda, R. gymnocarpa, and R. webbiana microphylla. First 2 I can find commercially in the U.S. but the last one is a bit difficult to locate here. Andre, I have some extra gymnocarpa that I collected in Plumas County, CA this past ...

Re: help with i,d.?

It's definitely not 'The Countryman'. Very difficult without the stems and foliage. I can see a bit of the foliage peeking out and it's no match for 'The Countryman' which is very, very matte with a reddish edge to the lighter green new leaves. This has quite a bit more gloss on it than you would en...

Re: Recommendations for healthiest Austin Roses

If you study Austin's roses (and their descendants by others) carefully, you will notice patterns with some of the frequently used older roses that result in seedlings in the yellow-orange range. If you are looking for better-than-average (compared to the usual, older English Roses') disease resista...

FWIW, I've always preferred matte leaves with a little texture to glossy leaves. Shiny reminds somehow of plastic, which is an association I don't really want when it comes to plants. Regarding leaf color, like others here I tend to prefer medium green to dark green. I prefer light green to bronze n...

I've grown Darlow's Enigma for a few seasons now and it is about as healthy as it gets here in Southern California, growing in partial shade. I don't know R. multiflora except from pictures, so I can't offer much in the way of comparison. The below link intrigued me in terms of its ability to genera...
