Sad, but looks about right.

Trying to get some width on those petals is going to dilute the species component considerably.

Wouldn't that be a case where self/sibling cross could probably be of use? Granted may be difficult if its a difficult breeder like bracteat. Just seems like a path thats often over looked and we see species crosses with flaws not in either parent used in further wide crossing before fixing flaws at the first species cross.

That's likely the most productive way forward. I've produced many bracteata derivatives. Most don't carry forward resistances. There are no guarantees when breeding roses. It takes luck and work and a lot of time to make progress.

I believe the petals are narrow on these photos as Burgundy has been experiencing severe drought since April. Rosa bracteata x chinensis has wider petals (see my pics).

Those narrow petals do vary somewhat with weather conditions.

Here's a case in point wherein the narrow petals carried into the second generation whilst staying diploid.

When integrating into triploid and tetra genomes no doubt the effect would be less pronounced.

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.

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.

Try Honey Bun by Scrivens.

Robert,

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

I'm really enjoying your photo contributions.

Showing growth habit of established specimens is very helpful.

Thank you

My first thought regarding identity was, 'Kitchener of Khartoum'.

Note, photos of specimens in the U.S. do not seem to match older descriptions.

An old nurseryman (OK, he's not much older than me) here thinks "Bishop's Lodge Linton Boy" is K of K, and "Jane Wellingham" is Red-Letter Day.

Ah! Well, he might know better than I. I've never seen either that I can recall in person.

Just thought I would throw out a possibility. Thanks, Robert

It's hard when both have fallen off the market. They had brilliance of colour, and were cheerful and fashionable; but without form or fragrance, they wouldn't sell now. Likewise Hawlmark Crimson and McGredy's Scarlet (which is shapely only as a bud), both of which have been preserved in old gardens in Western Australia.

They are museum pieces to be sure. It's important they survive in collections from a historical perspective but it's hard to justify a spot for them otherwise. My collection here has dwindled greatly over the years.

Thank you Robert for your suggestion. Help like this ensures that we cover all possibilities in our search for the identity of foundlings.
I think that 'Red Letter Day' was said to have no perfume.
K. of K. – (Kitchener of Khartoum) was supposed to have some.

(There are different roses for different folks. I struck another two 'Hawlmark Crimson' in the past couple of years because I think it is so beautiful. Inside our house there are a couple of museum pieces as well - and all the cupboards are full of old junk into the bargain.)

Jocelen's photo from NZ fits the description for Red-Letter Day - "going almost black in autumn"; except that his photos were taken in spring. We've been given two that we thought were incorrect.
We'll need to check "Jane Wellingham" for hips.
