Broom (shrub)
All the brooms and their relatives (including Laburnum and Ulex) grow in Europe, north Africa and southwest Asia. The greatest diversity one can find in the Mediterranean region. Many brooms (though not all) are fire-climax species, adapted to regular stand-replacing fires which kill the above-ground parts of the plants, but create conditions for regrowth from the roots and also for germination of stored seeds in the soil.
