Artichoke production in Italy Artichoke production in Italy Artichoke production in Italy has a long history. Italy is the world's largest producer of artichokes. With Spain and France, the three countries produce more than 80% of the world's artichokes. There are two theories as to its origin: artichokes may have come from the Levant, derived from the cardoon or thistle through a cross-fertilization process, while others attribute it to the work of Italian horticulturists. The first record of artichoke cultivation in Italy was during the fifteenth century in Naples, where it was considered a new food species. In 1466, Filippo Strozzi brought the first
Algebraic variety a variety to be "separated". (Strictly speaking, there is also a third condition, namely, that one needs only finitely many affine patches in the definition above.) Some modern researchers also remove the restriction on a variety having integral domain affine charts, and when speaking of a variety only require that the affine charts have trivial nilradical. A complete variety is a variety such that any map from an open subset of a nonsingular curve into it can be extended uniquely to the whole curve. Every projective variety is complete, but not vice versa. These varieties have been called "varieties in
