Krugiodendron ferreum, commonly known as the Black Ironwood or Leadwood, is a species of tree in the Rhamnaceae family. It is found in southern Florida, throughout the West Indies and from southern Mexico to Honduras. Originally described by Martin Vahl, its specific epithet is the Latin adjective ferreus 'iron-like'.
Krugiodendron ferreum is a small tree 5-10 m (15-35 ft) in height with oppositely arranged, emarginate leaves and small greenish flowers. The fruit is a drupe, 5-7 mm long which goes from green to purplish red as it matures.
It is widely cultivated in gardens or parks as a specimen tree, and is drought tolerant.
