Raphanus sativus var. longipinnatus
Daikon is a long-rooted East Asian radish. It is the same species as small red and breakfast radishes, selected into a very different root shape and size, usually with a milder flavor and a much larger, denser taproot.12
Radishes have been cultivated for thousands of years, and older crop references divide them into western small radishes, oriental radishes such as daikon, leaf radishes, and podded radishes.2 Daikon belongs to that oriental group: large, white, relatively mild roots that can be eaten raw, pickled, braised, simmered into soups, or salted and fermented.12 McGee notes that the skin carries a good share of radish pungency, so peeling or cooking can noticeably soften the bite.1
The Northeast growing fit is straightforward. University of Maine’s variety bulletin recommends Minowase Summer Cross #3 and Miyashige among the “Oriental” radishes that perform well in northern New England gardens.3 As a cool-season crop, daikon is happiest in spring or fall conditions rather than summer heat, which is one reason it tends to stay crisper and sweeter in colder parts of the season.4
The root is only one food part. Extension references note that the leaves, flowers, and seed pods are edible too, with the leaves generally better cooked and the flowers and pods useful when you want the same brassica sharpness in a lighter form.4 That wider edibility makes daikon more structurally interesting than it first appears: it is not just a root, but an entire spicy brassica plant with several textures to work from.
