Description and Uses
Pterocarpus angolensis (Sealing-wax tree) is a
tropical
tree from
Southern Africa . It is mainly grown for its
timber crops
, which have a
long shelf life. The crop is harvested by
total removing. It starts flowering after
18 -
22 years. The yield will be

medium. After
45 years the
tree can be totally removed as it reached its commercial and ecological goal.
Pterocarpus angolensis has a lifespan of
85 years.
