Product Details

It is no wonder that 'Mantanghong' is the most popular of the Chinese "beauty heart" radishes. This summer/fall-sown radish produces large, 3" round, mild radishes that can weigh up to 1 pound each! Slice the greenish white exterior to reveal a vivid, fuchsia interior. Whether you enjoy radishes raw, cooked, or pickled, these beauties are sure to be a star. Winter radishes are best sown in the late summer or fall, as short days trigger root growth.
