Re: Another virus that infects roses found
What I am particularly interested in include:
A picture of what the infected leaves look like.
A discussion of how the virus is transmitted.

Another virus that infects roses found
"RNA was extracted from ‘Hugh Dickson’ rose leaves displaying virus-like symptoms in Maryland, USA. Using high-throughput sequencing, we identified a new virus, tentatively named “rose virus R”"

Re: Rust
California is a very large state with many climatic variations. There is, like in most states, University based agricultural extension service publications which provide information for their climatic conditions. This is what was last updated 2/2020.

Re: Sweet Spirit
I would suggest one of the red Kordes roses since they were (in general) selected for both hardiness and disease resistance. Illusion is one example.

Re: Germinating in soil vs paper towel?
I prefer sand in baggie. It is easy to see if too wet or not wet enough. The sand can be removed with a strainer without the possibility of damaging the root. Sand does not support mold.

Re: Wasagaming seeds
Rugosa seeds normally float. Personal experience and: https://cdnsciencepub.com/doi/pdf/10.4141/cjps72-177
I did not apply the float test to my rugosa hybrids. I do not remember any extensive studies regarding the float behavior of first generation (or higher) hybrids.
