Re: Are Roxburghii flowers supposed to look like this?

No, like the above it looks more multiflora based.
The foliage is very wrong for roxburghii

Re: Are centifolia roses sterile

Picky and difficult from most accounts. I think heat may be a factor. I had Crested Moss set seed (some are germinating at the moment) this past season. It was hot and I really threw a lot of pollen at it (often pollinated each bloom 3 times a day for several days...seemed like less effort that look...

Re: hardiest reblooming diploid?

Although it makes me wonder if there is some difference in different plants of the same cultivar? Or is climate causing the difference? Or soil? Probably all of the above. Just as an example, Crested Moss set seed here (after digging for pollen in the first bloom it seemed more hassle than it was w...

Re: Alternate source for repeat bloom

The Angel Wing seeds are likely to vary from sources and country due to being a seed strain, the parent plants are going to be different for everyone harvesting seed so experiences will vary. I grew out around 5grams/0.03oz towards the end of last year here, the vast majority were singles, some appe...

Re: Yellow blend rugosa hybrid

The cross was Brite Eyes x Above and Beyond. It is one of the few juvenile bloomers I got out of well over 100 seedlings. I think these are real crosses because so far as I can see, Brite Eyes OP gives many more repeat bloomers thought I can't say for sure that all are. On a slight tangent because ...

Re: Multiflora Rose review

Maybe if it is just providing the root system of a grafted plant there may be some exception??? Not being from the USA and so not really needing to know such things....that would be such a giant oversight given potential suckering or the grafted plant dying resulting in the rootstock taking off.

Re: Yellow blend rugosa hybrid

'Nyveldt's White' may be classified as a Rugosa but that's a stretch since at the most it's 25% Rosa rugosa. In my opinion only a rose cultivar having at least 50% Rosa rugosa in its parentage can be classified as a Rugosa. It could be closer to 50% if none of the cinnamomea chromosomes were passed...

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

Murphy's law - single pink! That made me think of what the seed parent of 3/4 native looked like given Fragrant Cloud, then noticed it was bred by Tom so secret stalked his blog. Not single but pink (warm pink, but pink). I wonder if selfing may have strengthened the warmer colour, then again MR1 (...

Re: Alternate source for repeat bloom

As I reread it today it brought an answer, sort of, to something I was wondering about, how we get at least some plants that repeat bloom when crossing Rugosa with China, although not most? Part of that is going to be down to which Rugosa is used, many of the Rugosa's we currently use are known hyb...

Re: Alternate source for repeat bloom

But that (overview) brought a question to mind: If Rugosa has a functional copy, unlike China, than how is it able to repeat if it ought to be suppressing the repeat bloom? Also, is this true of others such as Autumn Damask? Possibly another gene results in some sort of disruption to the KSN gene w...

Re: Sure they improve, but how much, realistically?

I don't know. I think your conditions in Cal differ enough from here despite similar daylight/long summers/heat. Sydney is straight up acid soil, the whole region is largely a flood plain protected by dams...but for centuries/millennia beforehand large run off from the forest mountains into largely ...

Agree with the above just from a different perspective. So often the things praised on here (so...north america-ish) are not so great here in Australia. There's a lot of posts with praise for Carefree Beauty...I can't relate, it's not horrible but it's not a stand out health wise compared to the ave...

Re: Sure they improve, but how much, realistically?

I have never had a seedling change colour radically from young to old. I have...sort of, maybe. But it's in the purple range that seem very climate dependent (ie hot/dry = pale, cool/wet = saturated colour....like blue for you, baby faurax, etc). First blooms were near white now they are dark purpl...

Re: Question, disease culling, end of season.

Thank you. I ditched everything that was spotty earlier in the season, what remains now isn't particularly bad but is noticeable. I just notice some roses that are deciduous like rugosa, Dagmar Hastrup is spotless, her leaves just yellow and drop, while other rugosa leaves spot and yellow in fall bu...

Question, disease culling, end of season.

Just a question, with it being the middle of autumn/fall here many seedlings that were good all spring and summer are showing spots. Would you cull? Simply a question on whether end of season spots are a problem or expected....being in an climate where evergreens are a thing, unsure about these head...

Re: Unique black spot resistance gene from 'George Vancouver' is better characterized

Just from observations today and checking notes from previous years. Sunsprite isn't resistant to at least one of the strains here in Sydney as it's spotty now and has been in previous years so that's a pity. Thornless multiflora (grew from root stock) is entirely spotless. So may indicate Rdr1 and/...

Re: Rose “Ploids” made easy by P Wright

To some extent, even if sticking to a ploid but breeding too dissimilar (ie rugosa x china) will have sterility issues for the most part. Meanwhile plenty of triploids have some fertility or a lot (ie blue for you). I would stick in ploid if dealing with a once bloomer though, no point breeding once...

Re: Pollen from Canary Bird

Sadly can't help there.

Possibly go the other way and have someone in a warmer climate pollinate with hardy pollen and send you the seed...maybe something from that will survive for you?
