This is a super special rose. It's a fertile diploid with rich yellow blooms, which makes it unusual enough already. I suspect it holds very nice potential for breeding. It is also very healthy. I love the work Larry Davis is doing combining R. foetida genetics in new breeding lines with healthier modern roses.

The photos are gorgeous, a lush & rich gold-yellow.
Foetida gets a bit of a bad rap when it comes to disease: while there are plenty of weak ones, there are some hybrid foetidas that are actually pretty clean: Tip-Top & Mevrouw Nathalie Nypels come to mind.

Yes! And there are some remarkable Pernetiana-type HT’s well over 70 years old that have passed the test of time with flying colours. Beautiful, long-lived roses that get better and stronger with age - some very special ones among them.
The subject of this post looks beautiful - a gorgeous colour.

How do you explain it being diploid with known tetraploid ancestors?

Great question Jedmar. I suspect its parents are both triploid. I counted First Impression and it is triploid. Finding 13-1 as a diploid made me question the ploidy of 'Austrian Copper' and if it really is 4x like the literature lists it as. I got an own root plant from High Country Roses last spring and counted it and that plant at least is 3x. Another possibility is that 13-1 developed from an unfertilized egg of the maternal parent and doesn't have First Impression as a real paternal parent. My suspicion is that it is the first idea due to the races of black spot it is resistant to. It is nice how fertile it is. I have a plant in the cooler covered with hips and should take a photo and upload it for the hip shape, etc.

That's quite a fortunate outcome.

Very interesting, roses seem intent on breaking the rules!
