"Varietal denomination: ‘Sproulsun’.
SUMMARY OF THE INVENTION
The new variety of Rosa hybrida miniature rose plant was created during April of 2012 in Bakersfield, Calif., U.S.A., by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was an unnamed seedling (non-patented). The male parent (i.e., the pollen parent) was the ‘Radtko’ variety (U.S. Plant Pat. No. 16,202)."
