Hello Mrs. Routley, the sterilityt betriften only the Scarlet Fire heat as a mother plant. As a pollen donor it is an extremely fertile rose. In terms of content, I was concerned that James Mason is more likely to be the result of a reverse cross, i.e. more likely to be Tuscany superb x Scarlet Fire.
Tuscany superb x Scarlet Glow . One of the James Mason ( Scarlet Glow x Tuacany superb ) very similar rose.
Scarlet Glow (Hybrid gallica Kordes) single and large flowering hybrid. Makes very beautiful pear-shaped rosehips. But the nuts are sterile. Over 300 stratified nuts (from different years) have not produced a single seedling in 4 years. Several attempts to crossbreed Scarlet Glow x Tuscany superb have not produced any rose hips.
