Fennel The inflated leaf bases are eaten as a vegetable, both raw and cooked. Several cultivars of Florence fennel are also known by several other names, notably the Italian name "finocchio". In North American supermarkets, it is often mislabeled as "anise". "Foeniculum vulgare" 'Purpureum' or 'Nigra', "bronze-leaved" fennel, is widely available as a decorative garden plant. Fennel has become naturalized along roadsides, in pastures, and in other open sites in many regions, including northern Europe, the United States, southern Canada, and much of Asia and Australia. It propagates well by seed, and is considered an invasive species and a weed in
Flavour (particle physics) baryon number . They also all carry weak isospin, . The positive- quarks (up, charm, and top quarks) are called "up-type quarks" and negative- quarks (down, strange, and bottom quarks) are called "down-type quarks". Each doublet of up and down type quarks constitutes one generation of quarks. For all the quark flavour quantum numbers listed below, the convention is that the flavour charge and the electric charge of a quark have the same sign. Thus any flavour carried by a charged meson has the same sign as its charge. Quarks have the following flavour quantum numbers: These five quantum numbers,
