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.

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

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.
