The late Frank Hogan, who grew roses in the tropics (Mackay) was experimenting with Carabella as a thornless understock, especially for tall or weeping standards. Has anyone tried this? It would be nice if someone would pick up the baton.

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".

Seems a bit too deep a yellow and double? I had a plant from Thomas for Roses at one point, it was much more a translucent lemony colour and semi-double/almost single. (Unfortunately I lost it, and I've been looking for another one ever since!). Photo reminds me more of hemisphaerica or foetida persiana I guess.

The plant at Renmark came from Thomas for Roses. John Nieuwesteeg took budwood from Renmark - I don't know if that was the source of the rose photographed.

Maybe the petal count varies with the weather?

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.
