Scientific name: Tabebuia spp

Geographic origin: Central America and south America.


  • Sapwood: yellowish white colour.
  • Heartwood: dark grey with a very characteristic greenish shade.
  • Fiber: straight, usually intertwined or very intertwined.
  • Grain: thin to medium size.

Capacity of being impregnated

  • Sapwood: medium capacity of being impregnated.
  • Heartwood: low capacity of being impregnated.


  • Sawing process: ordinary problems due to hardness. Fast blunting.
  • Drying process: Slow. Little risk of deformation and crack formation.
  • Planing process: Difficult due to its hardness and high risk of repelling. Slow mechanisation is recommended.
  • Gluing process: tannins hamper proper adherence.
  • Nailing and screwing process: pre-drilling is recommended due to hardness.
  • Finish: rubber deposits can locally hamper varnish adherence.

It is currently a very popular sort of wood with much demand and very little supply.
It can be substituted by a large number of other species.
