- General Details
Northeastern South America
Color or Appearance :
Heartwood tends to be a pale olive green color with darker streaks. Yellowish green sapwood is poorly distinguishable from heartwood.
Grain tends to be straight to interlocked, with a fine to medium grain, and good natural luster.
Diffuse-porous; large pores in no specific arrangement, few; solitary and radial multiples of 2-3; tyloses and other gum deposits occasionally present; growth rings indistinct; rays narrow, normal spacing; parenchyma vasicentric.
Rot Resistance :
Greenheart is rated as very durable, and is also resistant to most insect attacks. It’s also considered to be one of the best-suited woods for use in marine environments, and has good weathering characteristics.
Generally somewhat difficult to work on account of its density, with a moderate to high blunting effect on cutters. Sections with interlocked grain should be machined with care to avoid grain tearout. Gluing can be difficult in some pieces, and precautions for gluing tropical species should be followed. Turns and finishes well. Responds moderately well to steam-bending.
No characteristic odor.
Allergies / Toxicity :
Although severe reactions are quite uncommon, Greenheart has been reported as a sensitizer. Greenheart has also been observed to cause a number of other health effects, such as wheezing, cardiac and intestinal disorders, severe throat irritation, and the tendency for wood splinters to become infected.
Comman Uses :
Boatbuilding, docks, decking, posts, fishing rods, pool cues, and other turned wood items.
