Contains even more sugars in relation to starch than su types, and as such is able to retain sweetness for 2 to 4 days with proper refrigerated handling. Somewhat less hardy than su types, it is known as a "tender" kernel and as such does not lend itself to mechanical handling. Does not require isolation from su pollen, although it is preferred. Some seed catalogs don't distinguish the heterozygous se (one se parent) and homozygous se (two se parent) varieties, but if they do, the homozygous se varieties will be labeled either se+, (se se) or SE.
