Re: Types of repeat-flowering in roses

If that is true, and if RoKSN-copia is somehow present in 'Stanwell Perpetual', it would have needed to be present already in the other parent (unless it appeared spontaneously, or is lurking in 'Autumn Damask'!). Potentially....but you have to go on a bit of journey to it. Of the roses tested in t...

Re: First R. setigera Results

Hopefully there is something we can do to get the male R. setigera allele into modern roses. Possibly something to explore in a sort back crossing (to species...not same cultivar) way (R. setigera x Modern) x R. setigera if the seedlings from that still seperate into male/female it may be enough mo...

Re: Experience with mini's?: Lavender Delight

- Sunny Sky -- relatively new. In a very tough location for me, but impresses me thus far, and sets hips. Maybe a bit less bullet-proof than those above. any further info? eg, do most pollinations take (or most flowers will form hips OP)? Seed per hip? any comment on germination rate? Kind of stuck...

Re: Any experiences with these roses from Burlington's?

Can only comment on Sweet Chariot as it's the only one here (Sydney, Australia), so heat isn't really an issue but does look like we have higher rainfall (especially the last 2 years because of La Nina and I didn't have it during the drought years). It's small, flowers a lot, basically every flower ...

Re: Your superlatives for...

Mark, that is pretty remarkable. My mind being on the mauve line right now, I'm wondering if MotH crossed with R. foliolosa might yield some really deep rich hues such as foliolosa yields when crossed with rugosas. I had wanted R.f. primarily to see if I could coax any of that deep purple wine colo...

Re: experience with Ramblin Red?

I can't comment on RR, it's not released here. Powdery mildew is the norm here, especially in seedlings, pretty much regardless of parents the seedlings will be mildew babies. The only seedlings that are consistently free have been R. Spinosissima...no idea why, I've grown a lot of species seed and ...

Re: Weird colour breakage

I have never seen 'Baby Faurax' go white, but maybe San Jose, CA, didn't get hot enough. I recall a "heat wave" that only got into the 90s F. On the other hand, on one occasion I found BF going almost egg plant-purple in cool, cloudy, damp weather. It's not a common occurrence like with Blue For Yo...

Re: Weird colour breakage

I don't have any records of it blooming last year but it may have had some disease issue, caterpillars or dried out (shriveled up buds) that disfigured it in some way. I tend to neglect modern x modern...they're time fillers of pigment (there's only so much pink and white you can look at with specie...

Weird colour breakage

Assume some sort of damage related, just interesting looking, like someone dropped some water on ink

Just kind of interesting how the reverse doesn't really seem affected by the lighter reverse, while the purple is.

Re: Oddities of gall

It's the strongest reason I completely avoid any breeding line containing Ballerina and The Fairy (Carpets, Drifts, etc.) as those galls appear almost over night. Any guesses as to why? Not that it's an issue here, but always interesting to know of potential issues of things I've picked up (Carpets...

Re: Rosa Helenae Hybrida Off Spring Success in NAmerican Cold Zones?es?

'Koresia'/Friesia/Sunsprite is usually a black spot disaster here in Maryland, but I believe it is one of those that is only susceptible to a limited number of strains This is correct based on some research from David. Sunsprite has a Rdr3 gene, which gives resistance to some strains of blackspot b...

Re: surveying polyanthas treated with oryzalin for polyploidy

Slight tangent, but did the more multiflora polys that didn't cross well with moderns, stem from the angel rose/wings seed? I know you had selections of those in the past. Probably doesn't help at all and who knows how distant from each other the seed strains are at this point, but may be of interes...

Re: Taming The wild Ones

Banksiae seedlings and hybrids are notoriously mildewy. At least the straight seedlings out grow it and achieve the high degree of resistance it demonstrates. Do they grow out of it without assistance? Or do you intervene? I get a lot of mildewy seedlings from some things (even things that surprise...

Therese Bugnet has a copy of RoKSNcopia which possibly accounts for that.

Eyes for You can be difficult. For me it's refused to set seed whether intentional or OP (over the last 5 years) but I know others have had success using it for seed. It's also not been big on releasing a lot of pollen, workable if you stick at it but I've had to work at it. If you're thinking of us...
