Tetraploid, too. I guess one cultivar can have multiple ploidy depending on where the tissue (root, leaflet, or pollen) was taken, as well as if it mutated and spread by mass industrial production. Sometimes simply unstable, as well.

Or that conventional measurement methods are reliable in almost all cases, but not all.

I wish this study had included Tropicana, Red Tropicana, Super Star Supreme, and/or Climbing Tropicana. Tropicana is a unique case of a triploid behaving as a tetraploid, that readily gives very large flowers and large plants, and small flowers with small plants to its kin.

Some of the ploidy stated in this publication differ from that of other sources. The method used is Flow cytometry to get an estimate. Only a few cultivars have been "confirmed with microscopy". This might be a reason for the deviations.

I'm going to hold off on changing ploidy as currently stated until we get further confirmation.

The article of Harmon, Byrne et al. on Cytogenetics etc. refers to two articles by David Zlesak, from where the chomosome counts came.

I've corresponded with David.

He attempted to clarify the situation but results were posted prematurely.

Until we establish clones were identical results are in doubt.

Given that the study that estimated it to be triploid used flow cytometry to determine the ploidy, a far less accurate method than direct counts I’d be inclined to believe it’s diploid. And considering the parentage tree it’s not really surprising. Both parents are possible triploids and they could have easily produced a diploid seedling when crossed

Breeds like a diploid too.

I came across this rose at a hardware store. I noticed that the foliage is rather small, and could almost be called miniature scale. The canes seem thin and flexible, giving the rose a bit of a tangly, vine-like appearance. The plant was filling a fairly large container, but it looked like it might be nearing the natural limit of its growth. The leaves were overlapping quite thickly at the center of the plant, and I think it could have used a prune to thin it out a bit.

The blooms were rather small, and semi-double to double, but really nice in color, and with a charming overall effect. A lot of blooms and buds were on the plant. The blooms do have a pleasant fragrance. It is a little hard to describe, but I guess I would call it slightly sweet and warm, and mild to moderate in strength.

Taken all together, it seems like a nice plant, especially for container gardens.
