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) together with baryon number (which is not a flavour quantum number), completely specify numbers of all 6 quark flavours separately (as , i.e. an antiquark is counted with the minus sign). They are conserved by both the electromagnetic and strong interactions (but not the weak interaction). From them can be built the derived quantum numbers: The terms "strange" and "strangeness" predate the discovery of the quark, but continued to be used after its discovery for the sake of continuity (i.e. the strangeness of each type of hadron remained the same); strangeness of anti-particles being referred to as +1, and particles
