Dear HMF, your entry for Rosa spinosissima L. includes a list of synonyms, etc. (highlighted in blue) linking those names to this entry. But at the bottom of that page Rosa tschatyrdagi Chrshan. is mentioned but not included in the “Blue list” so it cannot be found by the Search feature of the HMF website. Could you please include Rosa tschatyrdagi in the “Blue list” too. Thank you!

We have another 21 synonyms listed as "Hidden Names", as they are uncommon synonyms which would be quite confusing if listed in the Synonym section. Rosa tschatyrdagi Chrshan is already included under Hidden Names. If you search for it, you should land on the page of Rosa spinosissima L.

Well, that explains it! A few days ago, I was listening to the song “My Wild Irish Rose”, and while I know it was written about someone’s sweetheart, on a lark, I searched it, and 'Rosa spinosissima L.' popped up. Since I didn’t know there were hidden synonyms, I figured it was an error.

Is there any way for premium members to access those less-common synonyms?

Dear jedmar: I cannot find the link to “Hidden names” . Even using the “Advanced search” feature, entering Tschatyrdagi at “name” does not link with anything. I make this inquiry because an article was recently published by the American HRG [The Rose Letter] where this species (tschatrydagi) is discussed. I posted photos of tschatyrdagi and rupincola at the entry for spinosissima because that seemed the appropriate (and unfortunately only) place since they are considered synonyms but searching for “tschatyrdagi” will not take you to them while a “rupincola” search works. Also I can send a link to the article if you can give me an address. But the article published by the HRG has an error, a whole paragraph was omitted disrupting the continuity.

tschatyrdagi does not work for me with "Best matches", but with "contains"

Searching for 'tschatyrdagi' should work for both search methods. It's likely the partial italicization of the name is causing an issue - we will investigate.

Thank you for taking the time to bring this to our attention.

Does anyone know whether R. Spinosissima is self-sterile? And are the garden hybrid varieties also self-sterile?

I have seen this mentioned in an article I was just reading, and was left curious, especially as my pink garden variety rarely produces hips for me, despite flowering prolifically.

The article in question is "Durham Wild Roses" by J. W. Heslop Harrison, for those that are interested.

Many thanks in advance.

Likely varies to some degree with species from one individual to another, some being better hip parents than others.

I have an unknown white (someone bought an old place and no labels and I got a sucker...I don't recommend sticking a spino sucker in the ground, spreads) spinosissima, assume just straight species given all it's habits and traits.

It doesn't set a huge number of hips (maybe half of flowers) but it sets them. Of those that germinated, many of them seemed like straight spinosissima (no others in the garden at that time except the diploid pimps like hugonis on the other side of the garden), while others were obvious hybrids with things near it.

in the references there's one "Cross- and self-compatibility in various species of the genus Rosa"

which says
"R. spinosissima L. Ploidy, Ploidy 4x
Pollen fertility 97.7%
Selfed Fruit set 75.8%
Selfed Seed set 58.7%"

which isn't too far off what I'm seeing with mine (just less hip set)

Meanwhile at a public garden nearby there is plants of Single Cherry (and something labeled Single Purple) that produce a lot of hips. Seedlings from those show no obvious hybridity but who knows if they are self or just crosses between the two.

Great answer. Very interesting stuff. Thank you.

bloom: once-blooming spring or summer is incorrect.
In Flanders, this rose blooms very early, from May on and can continue for a long period. In September-October, there often is a rebloom.
Prone to rust.

The description says "pink and yellow". But as all the photos show, this rose is white.

White is the typical color of the Scotch rose, but color variants turn up ... or so I've read.

Sabine (1822) gave an account of the origin of the first double Scotch roses in assorted colors.

I am indebted to Mr. ROBERT BROWN, one of the partners of the firm at the above period, for the following account of their origin. In the year 1793, he and his brother transplanted some of the wild Scotch Roses from the Hill of Kinnoul, in the neighbourhood of Perth, into their nursery garden: one of these bore flowers slightly tinged with red, from which a plant was raised, whose flowers exhibited a monstrosity, appearing as if one or two flowers came from one bud, which was a little tinged with red; these produced seed, from whence some semi-double flowering plants were obtained; and by continuing a selection of seed, and thus raising new plants, they in 1802 and 1803, had eight* good double varieties to dispose of; of these they subsequently increased the number, and from the stock in the Perth garden the nurseries both of Scotland and England were first supplied.
