Boxthorn

Boxthorn is a member of the Solanaceae family, which includes other plants such as silverleaf nightshade, tobacco and tomatoes. Boxthorn is an aggressive invader of pastures, roadsides, reserves, remnant bushland and waterways.  It forms an impenetrable, spiny thicket that inhibits the movement of stock and provides a haven for feral animals. Many insects, including fruit fly, the common house fly and the tomato fly, breed in the fruit of this weed.
