I love this rose for its color. It may be a small in size plant but I always see it when it blooms. I might try grafting it onto Fortuniana root stock. I have a no spray garden and it doesn't seem to mildew. We are zone 9B. It is hot and has low humidity for most of the year.

Where does this rose get its hardiness to zone 2b from??

Difficult to imagine from the parentage stated in Modern Roses 10, isn't it? However, if we modify the pollen parent from 'Von Scharnhorst' to 'open-pollinated seedling of Von Scharnhorst' (as stated in the note) then it is quite possible that a very hardy nearby rose in the Experimantal Station played a role.

That would make sense. Thank you Jedmar.

If you check the photos of hips of Rosa virginiana on this page, you will see that some of the pictures show smooth hips, while others prickly hips. In Roessig's 1801 drawing, he differentiates between Rosa lucida (prickly hips) and Rosa virginiana (smooth hips). So, is the synonym incorrect?

Jedmar, I have no time right now to do more than say, I found your question so interesting. We have some rain coming up in the next day or so and I really look forward to hunkering down then to look closer at the references and comments. (I only wish I could read those French references).

Patricia, I have added the translations from French, but mind that I am no botanist!

You are very kind. Thank you for doing that Jedmar.
The complexity of the various references brings home to me that none of us are botanists. Me especially - I am just an old lady gardener.

I recall once, was it Karl? who said that a bush can produce prickles at will, and I have certainly seen this type of behaviour on the odd rose or two in my own garden. Simplifying the names here, I am wondering if R. virginiana / R. lucida also does this from time to time. I didn’t note the hip prickles on my bush for many years until I photographed it, but perhaps I didn’t look closely enough in the early years.

I note that Rossig’s 1801 illustrations show
R. virginiana: a smooth (a little pointed towards the base) hip
R. lucida: a prickly (globular) hip.
Yet in his text he writes of
R. virginiana: “Ovary almost globular, slightly bristly”.
R. lucida: “a Globular, flattened ovary”. (No mention of bristles)

The 1817 reference is a little confusing to me as Thory has written of R. lucida having “Receptacles and pedicels armed with reddish glandular hairs” and “heps depressed globose red”. I can discern the hairs on the top bud in the illustration, but only with a magnifying glass. Knowing that the receptacle is the early stage, from which the hip is formed much later, I can only note that Redoute has drawn a very smooth hip.

In the 1817 reference Thory mentions that the R. lucida blooms do not last for more than several hours. In my 2013 reference I had noted “They seem to have come and gone before I can get the camera out.” I am going to add to my own records the possibility that my rose may be R. Lucida. But I really do not have the knowledge to do more than that. I do notice you pouring in the early references for this rose, and I thank you for your dedication and sharing.

Hi Robert, Can you give a specific example please.

Thank you Robert. We will be investigating.

The parentage by name did not work earlier but is now. We've not made any changes so I have to assume we have a website server utilization issue to address. We will follow up. Thank you for the heads up.

I just tried it again and had no success. It comes up a blank page.
Reply #6 of 12 posted 5 days ago by HMF Admin
Yup, came up blank for us now too - most definitely a resource issue. We'll get on it.

Thank you for your attention to maintaining this wonderful resource!

There is something wrong with the parentage for one of this rose's parents, A parent rose along the line has an error causing our software re-read the parentage database repeatedly (> 35000 times). We'll sort it out.

Sorry for the trouble. Sounds a nightmare to me.

FWIW I found a page with a similar situation the other day. I hope there aren't too many of these glitches in the system.

It could be a single rose but that's just speculation at this point. HMF lineage maintenance software does a good job of ensuring a plant's parentage has been entered correctly but a later change, like an unexpected deletion of a rose, can cause an issue although usually not of this nature.

We'll need to write some software to search out the errant rose(s) parentage so it may be a few days.

Another example would be helpful.

This issue has been corrected. It did turn out to be a single rose with an incorrect, circular parentage. We used the opportunity to update the parentage software so you'll find it is quite a bit faster. The other rose listed is working now too.

Meanwhile, we still need to determine if any other plants have been incorrectly recorded as well as how our maintenance software allowed this is the first place. We will continue to pursue this...

Thank you for taking the time to contact us and for your patience.

As usual, your attention toward maintaining the database is impeccable.

I'm amazed you can keep it running as well as it does.

Thank you! Robert
