Cultivation

Origin: at Auburn, Ala, by J.D. Norton, Auburn Univ. Introd. in 1988. Parents are siblings of double backcross of Starcher No. 1 (a native selection at least partly Prunus angustifolia) to Methley; cross made in 1965; selected in 1975; tested as Santa Rosa A-S. Tree: vigorous and upright on peach rootstock; moderately resistant to bacterial spot and bacterial canker; tolerant of plum leaf scald and brown rot. Chilling requirement about 750 h. Better adapted to the humid Southeast than is Santa Rosa, which it replaces. Flowers large, self-infertile; blooms with Santa Rosa. Fruit: large; skin red; flesh amber, firm, high quality. Ripens a few days after Santa Rosa.
