This rose should come with a warning label; I became entangled while mowing and was able to escape only with great difficulty. Don't even think about training it; the wood is very heavy and stiff and the thorns are evil.

I planted this in a rather dry area on a six foot panel fence in north Texas (Dallas area) and the first season it covered 25 feet (3 panels). I might go back to visit it but I surely would not admit to any of the 3 neighbors who may have had a close encounter that I was the guilty party.

A rose for a country estate, NOT the suburbs.

Does Countryside Roses still exist as a nursery? It is listed as a source for many roses but its website appears to have been hacked, their number is disconnected and they have had no reviews in Dave's Garden since 2010.

Are there any China or China hybrid roses with yellow blooms still in existence? It almost seems as though they are all extinct.
Yet there are many yellow HT's around today which must still have some of the early yellow China hybrids in their genes.

All existing early yellows (Desprez, Devoniensis, Lamarque, Le Pactole) carry Noisette blood in addition to the Tea. The pure Chinas & Teas have died out. However, Hume's Blush must also have had yellow genes, as Knight's seedling of 1823 shows ('Yellow China Rose').

Yes, even "Smith's Yellow China" was a Noisette/Tea. It seems that a lot of the early yellows with a lot of China and Gigantea influence were prone to balling and very susceptible to disease and cold.

The hypothetical "yellow genes" are actually the lack of a gene that codes for an enzyme that degrades carotene. A 40-carbon carotene is snipped into two pieces - a 13-carbon and a 27-C. The latter is then snipped again into a 13-C and a 14-C. These smaller carotenoids can then be oxidized, producing the most potent perfumes: including β-damascone, β-damascenone, β-ionone. These are known as the rose ketones.

The Musk rose and its allies start with different carotenes than the original Tea rose types. Some of the Tea-Noisettes inherit the Musk rose carotenes along with the Tea rose's lack of carotene degrading enzyme(s). Thus, the more deeply colored Tea-Noisettes are showing carotenes that would be degraded and oxidized into perfume in the Musk rose itself. This can be apparent even in crosses between Noisette and Tea, such as Smith's Yellow, where part of the carotenes are degraded but the remainder provide color.

This also occurs in some of the Luciae hybrids, such as François Foucaud. Here, again, the the richness of color is partly due to the Luciae carotenes remaining intact and visible, while the remainder provide a delicious scent.

Similarly, the yellow Banksiaes are less fragrant than the white forms that smell of violets (β-ionone).

Many of the Pernetianas are richly perfumed, often with a somewhat different scent than HPs and other roses. Rosa foetida produces its own distinctive carotenes, which can be degraded and oxidized into equally distinctive scents.
