In David Elliott's photo from Leiden, it doesn't look like it's thornless. One reference mentions large prickles.

My love affair with the Penzance roses began in the Arnold Arboretum about 30 years ago. They had a grove of several that were 10' tall free standing shrubs. Checking the label, I found they were 'Greenmantle' and Malcolm Lowe in Manchester, NH was the source of the plants. So I decided that for a wild garden the Penzance roses were what I needed. I headed up to NH where I bought 'Greenmantle' and a selection of OGRs.
Over the years I bought all the cultivars I could find, including 'Amy Robsart' which I still have. All of them, given enough time to mature, will make a tall free standing shrub. I have never managed to reach the magnificence of the Arnold Arboretum grove, but even in zone 4, if given enough time and manure, they will make a free standing shrub with canes arching gracefully from about 10' (over three meters).
All the Penzance roses I have seen have typical R. eglanteria canes and thorns.

The reference from 1900 speaks of "rare and strong" prickles. No mention of arming in other sources. One German nursery mentions strongly armed canes. A further case of mislabelling?

Palustris, I see you grow Amy Robsart. Do you think the "Eden Valley-Springton sweetbriar" (photos posted under Amy Robsart) is the same rose? If not, which? Also, I see you have an interest in ramblers. Would you please look at "Hawthorndene Tennis Court", and see if it's one you've grown? I've seen it in two places in the Adelaide Hills (zone 9b) and in northern Tasmania, don't know the zone but possibly 7. We'd also appreciate knowing if you recognise the "Eden Valley-Springton Yolk-Yellow Rambler".

I'm wondering if Madame Alfred Carrièrecan be grown as a large shrub? Thank you.

I have only ever grown it on a strong supporting structure, something it seems to need because it makes such long growth, and I can't recall seeing it grown as a shrub or hedge. I haven't tried to keep it lower or more compact but perhaps others have and will be able to advise how it responded.

Thank you for sharing your experience. It does sound like it needs support.

When I was living in San Diego 25 years ago there was a huge free standing MAC in the Quail botanical garden. The plant must have been many decades old and really impressed me with its size and its attractive overall shape.

Hi, I really enjoy this website, thank you so much for this incredibly useful resource! I would like to ask if there is or could be a way to filter the results in the pictures. I am not trying to be mean but some of the entries are just close-ups of the flower for multiple pages. Some users seem to post dozens and dozens of these close-ups which makes it really tedious to search for a full bush shot, let alone other plant parts. Would it be possible to further implement the current labeling system, so that accurate labeling of pictures (bloom closeup, whole plant, hips, etc) is mandatory? Would it be possible to filter the results to exclude the pictures posted by a specific user? Perhaps it's easier said than done. Either way I really enjoy the website, thanks again!

You are preaching to the choir when it comes to me and the rose photos here, on Flickr, and every other site with rose photos. But what is important to remember is that this site is dependent on user's contributions and we must respect their contributions even if imperfect. Without user photos, this site would be much less useful.
That said, I really don't think that close up photos of the center of a flower contributes in any way to help identify a plant nor are they artistically attractive. I like to give a flower space to "breath" in a photo, that is to say I like to show space around a flower because it adds some sort of context to the photo as well as giving a more complete view. So, I am saying that adding some artistic sense can also contribute to helping identify a plant by the flowers. After all, why does HMF show photos of the flowers? I would argue that rather than being primarily a venue for artistic expression, it is a resource for plant identification.
To that goal, it then becomes important to photograph the entire plant: flowers, stems, prickles, leaves and the entire bush. Some of the roses on this site are extremely rare or the flowers can be very similar to other rose cultivars. In these instances particularly, it is important to show details that help in plant identification. Sometimes it comes down to minor details like the length and shape of a sepal, or the number of glandular bristles on a peduncle.
I don't think you can filter out user's photos, but you can definitely follow a user whose photos you find useful, simply by clicking on the user name and checking out their photos.
I have already said enough, but while I am pontificating about useful photos to help identify a plant, it is important to point out that the provenance of the plant is also very important. That's why HMF asks when the photo was taken and the provenance of the plant. For instance, there is occasionally a vendor who has an incorrectly labeled rose. Those photos eventually end up on HMF mislabeled. If we know the vendor, we can then help them to correctly identify that rose. Even the date of the photo can be useful. If I want to visit a garden in a different region, I would like to know when the roses in that location flower.

I agree with everything you said Palustris. I think the filter could be more effective if it were mandatory to label the pic. When you upload a photo, there are multiple boxes you can tick to categorize your picture as a pic of the whole plant, or blooms or foliage, or hips/seeds, etc. But this is currently optional. As a result, the filter is currently almost useless, since nobody seems to use it when uploading. My comment above was spurred by a search for pictures of a rose, in which I limited the results in the list options to "canes/stems/branches" and got only page after page of bloom closeups. Making labeling mandatory would not fix previous uploads, but hopefully new ones would be more accurate.

Making the category mandatory could be as simple as requiring the tick box to be filled before the upload can be completed.
While I always tick the category of photo type, I didn't know there was a way to search on them. I will have to check that out as it certainly could be useful.

Hello, i'm currently searching a specimen of this real rosa gallica 'léa'. Where did you find it? Is it possible to buy you some cuttings or root-suckers ? Thanks

It is very disappointing when photographers don't provide information about the source of the rose. "in my garden" is not helpful. Purchased from from NNNN or identified by NNNN or photographed in Rosarie de NNNN is very helpful.

I'm really sorry for not having replied immediately. Callimarcio's answer is absolutely correct. My rosebush comes from the Roseraie de Berty, in Ardèche (France)

Thank you very much for your reply and precision. I've ordered the grafting of two plants of this variety at this nursery in France. Best regards
