General description
The sapwood is creamy white and may be streaked with the heartwood
varying from pale yellowish brown to olive green. The green colour
in the heartwood will tend to darken on exposure to light and turn
brown. The wood has a medium to fine texture and is straight grained.
The size of the sapwood and some physical characteristics will vary
according to growing regions. The wood has many desirable characteristics
and is suitable for a wide variety of important uses. The tulipwood
tree resembles the shape of the European poplar, hence its name
in USA.
Working properties

little tendency to split when nailed. It takes and holds paint,
enamel and stain exceptionally well. For additional information,
