I grew "Thomasville Old Gold' in the desert climate of Palm Springs, California for 8 years, after having grown it in Las Vegas, Nevada, for 5 years. The plant does prefer a dry climate as it is susceptible to mildew in cooler, more humid climates. It grew very well for me in a shady spot protected from wind, with only about two hours of sun in the morning (In Palm Springs).
I live in Idaho now and I still grow this rose in a pot. I spray water on the leaves in the morning often, to wash dust off the leaves; also, I make sure to never let the soil dry out completely, for that invites mildew. (I grow all my roses organically). This rose has a wonderful fragrance and color. The texture if the petals is similar to the finest Chinese silk. I wonder what its true name might be? It does bear a resemblance to several historic paintings.
It is a tender rose as far as cold and it hates cloudy, gloomy weather, yet thrives in shade in the dry air of the desert, where it is very healthy.
