Re: purple stamens

Kim, are there hulthemias with purple anthers as well? The very few I can think of off-hand seem to have yellow anthers, though with colored filaments. They can be, but Im seeing more red/dark red. I've raised a lot of seedlings from Sweet Spot Calypso (a lot of health issues though) and it varies ...

Re: Coutts #4

Stanwell Perpetual indicates that rebloom and long spiny canes can happen together...just maybe not in the conventional way...granted the question is hypothetical. Given most of the hulthemia on the market (at least here, mileage may vary) are physically so removed from the species apart from the bl...

Re: How common is this?

Do you know the roses 'Little Pet' and 'Félicité-Perpétue'? The last one is a climber, the first one is a mutation from it and and a mini rose, Félicité-Perpétue is only blooming once, while "Little Pet" is flowering all the time. Most of the dwarf roses flower continuously... related observation O...

Re: Grandiflora or Hybr. Floribunda?

The other part of it is rose shows/societies/trials, they'd be playing some part in keeping classifications going via awards. Here in Australia, some nurseries don't even bother with the Floribunda/Hybrid Tea distinction. eg Wagners Some of the early "grandiflora" can be monsters though, June Bride,...

Re: Petite Knock Out Rose - AVOID

These days, DNA techniques are so cheap that you don't really need a specific single gene to tag. Just compare a bunch of markers on several chromosomes that represent the haplotype (particular arrangement of different alleles in this cultivar). Works exactly like the DNA database that the govt use...

Re: Petite Knock Out Rose - AVOID

Given the assumption the tracer gene (if it exists) is from the unknown grandparent, isnt it statistically likely the gene will fail to pass on?

Re: When to expect Rugelda F1 first blooms

Joe, Do your AE seedlings that are in bud show any traits from AE such as narrow leaves or thorniness? Ive not found narrow leaves to be particularly dominant from Ann Endt seedlings, including OP....very thorny though (although to be fair the only low thorn near it is Therese Bugnet which is super...

Re: Germinating seeds

Yes and no. It depends a bit on class/species. I mean things closely related to species that rarely/never seen freezing temps arent likely to need stratification. Probably also location. My seeds often never seen spring. Im in Sydney Australia (very little chance of freezing, even then never really ...

Re: Is every rose seed completely unique?

I feel that we make the mistake on this forum of assuming that a particular rose species has a fixed set of characteristics. I respectfully disagree with Philip's above assertion that the differences are rarely noticable. I seek and cherish variations within a species. I would agree with this. Ive ...

Re: What is the easiest and hardest steps in rose breeding?

Hardest initially will be just letting seedlings go that have some problem or accepting the number of weak seedlings that'll die off from the modern classes (die off in species and older classes is much much much less for me). Letting seedlings and unproductive plants go is hard. Next would be figur...

Re: Finally a splotch!

On the blue topic, if you can track it down (it was bred in th USA) Man of Steel is distinctly grey/blue when the flowers bloom inside. Outside theres a pink/lavender hue and its paler, likely some reaction with sun/UV, inside its closer to Turn Blue and just very blue compared to the usual "blue" r...

Re: Finally a splotch!

I can also confirm it's dominant gene. Having raised many hundreds (or more) seedlings from the diploid Sweet Spot Calypso, many being selfed OP's (every flower turns into a hip, I sow everything...), there's instances where the blotch isn't inherited (indicating SSC is heterzygous for the gene/s) o...

Re: All A'Twitter x Yatkan

I just mentioned Stanwell because I recalled that post above from Ivan to some extent (that he got hips and seedlings from it). I figured given it's one of the commonly "sterile"/doesn't set hips in similar manner to Crested Moss and Robusta (which have set hips for me this season) that it's trigger...

Re: All A'Twitter x Yatkan

I don't know if it's the heat wave or the excessive amounts of pollen (ie 2 or 3 times a day for 5 days...seemed easier than looking for pollen that may or may not be found) but I have hip set on Crested Moss that I got this year. A lot of them seem to be phantom pregrancies (ie I can't imagine seed...

I use latex gloves when dealing with hips, between dermatitis reactions with the hairs, how glandular some of them are and staining potential from the hip flesh/juice.

Re: rose hips without inner hair?

I checked one of the Calocarpa hips. Very little hair, more like a very light fuzz inside, easy to scrape out. A lot of seeds though (30 - 40 range).

The very low hair is possible evidence toward Old Blush...will check that when possible.
