The two varieties known in this country are the English and the
French--distinguished, also, as early and late. The French only is
suitable for cultivation here; especially in the colder regions, as it
is earlier. This is cultivated in every way like cabbage. In several
respects it is preferable to cabbage; it has a more pleasant flavor, and
is more easy of digestion. It is excellent for pickling. Seeds may be
raised in the same way, and with the same precautions, as cabbage; but
it is generally imported.
