Raphanus raphanistrum, the
wild radish or
jointed charlock, is a
flowering plant in the family
Brassicaceae. It is sometimes claimed to be the ancestor of the edible
radish,
Raphanus sativus. Native to Asia (or, according to some authorities, the
Mediterranean), it has been
introduced into most parts of the world, and is regarded as a damagingly
invasive species in many areas, for example Australia. It spreads rapidly, and is often found growing on roadsides or in other places where the ground has been disturbed.
