Daikon or mooli, Raphanus sativus var. longipinnatus, is a mild-flavored winter radish usually characterized by fast-growing leaves and a long, white, napiform root. Originally native to continental East Asia, daikon is harvested and consumed throughout the region, as well as in South Asia, and is available internationally. In some locations, daikon is planted for its ability to break up compacted soils and recover nutrients but is not harvested.
