Description China S-2 is a satsuma mandarin selection originating from survivor trees identified after a severe freeze event in China. These selections were evaluated specifically for cold hardiness, fruit quality, and tree vigor, with S-2 standing out for its later ripening window and dependable performance. By maturing later than many satsumas, China S-2 allows sugars to fully develop while retaining the tender, easy-eating texture satsumas are known for. It is an excellent option for growers looking to stretch the satsuma harvest season without sacrificing resilience. Overview Cold-selected satsuma mandarin with proven resilience.
