The tallest of all South African bush-willows, the leadwood grows some 20m high. These slow growing trees mature as magnificent specimens with a greyish appearance and a spreading canopy. Long-living some have been dated at over 1,000 years old. They occur in the warm dry bushveld along rivers and watercourses.

As a result of carbon dating some leadwoods have been aged at over 1,000 years.
Due to the leadwood being so dense, 1,200 kg per m3, it is actually termite and borer resistant. As a result, even after the tree has died, it will remain standing for hundreds of years to come.
The leadwood is so named because of its extremely heavy heartwood which weighs 1,200 kg per m3, this is so dense it will sink in water.
