Is this rose fertile? I wonder if it could be crossed with Goldbusch to reinforce color and foliage fragrance into the cross, but still keep remontantcy.

Just randomly on this.
Potentially.

The article above is a bit of an overview of canina type x spinosissima, the F1 had the unmatched chromosomes like canina types but in the F2 diploid, tetraploid, pentaploid and hexaploid resulted. Add in the high seedling mortality rate and it looks like a lot of tetraploids of usual chromosome pairing turn up. Whether this holds true with other crosses is unknown but worth exploring.
It may be a case of doing whatever cross you intend and then selfing/sibling cross the seedlings for the F2 generation (likely in very large numbers as in a tet once bloomer x modern F2 the juvenile bloom rate is about 1 in 36. So out of 1000 seedlings only around 27, canina type will make those odds worse, possibly far worse) with the unbalanced chromosomes I'd be looking to sow several thousand seed for the likely very rare juvenile bloomers with scented foliage. On the plus side if juvenile blooming, can be fairly certain it's tet, tri or dip as anything of a higher ploidy should still be a once bloomer.
In theory, seems possible, just low odds.

So far liking the foilage on this more than Lord Penzance, deeper colour, sheen, shape....granted I haven't experienced it going to blackspot yet.
Doesn't seem as vigorous as Lord Penzance though, possibly a bit slower to start....foetida and talisman seem similar, growing but haven't exploded in rapid growth like everything else, may fall into the type of rose that blooms first and then puts on the bulk of it's growth.

When I was in Belgium this year , I came across a Lady Penzance full of OP hips. I could n't resist grabing all that was on the plant. The seed looked very viable and was cleaned and sent to my adress here in OZ. Put down at least five containers of sown seed today of around 150 seeds. I am not sure if this cultivar is in Australia, Patricia or Margaret ??. They do not have to be stratified as they went through a very long cold European winter this year .

Ross Roses have a stock plant - I don't know if they're listing it, as my computer is being uncooperative. I grow Lord Penzance (which has suckered because the mulch extends above the bud union), and I love the waft of sweetbriar through my rose garden. They're good solutions in this state, where R rubiginosa is a common roadside plant but a declared weed, and therefore illegal to grow.

Hi Margaret,
I got Lord Penzance this year, it's only a few months old (from being bare root) so it may be an age thing or climate but does yours bloom and drop it's petals within a day? I'm also not getting a green apple scent it's more spearmintish (toothpastey almost). Wondering if I just smell the alleged green apple smell of sweet briars differently or if Lord Penzance is unlike most.

The flowers don't last long. To me the leaves have the same sweetbriar scent as the roadside weed R rubiginosa.
What I thought was a sucker on my previous plant turned out to be a seedling, once it was beyond salvaging.

Thank you. The fast bloom is a bit disappointing but hopefully that will be improved in the next generation with some of the crosses I've (attempted) made.
I'm very confused where this green apple scent description arose now, might be from the astringent like notes, it's just not green apple to me at all.
