heartwood

English

A section of a Yew, showing 27 annual growth rings, pale sapwood and dark heartwood, and pith (centre dark spot). The dark radial lines are small knots.

Etymology

From heart +‎ wood.

Noun

heartwood (countable and uncountable, plural heartwoods)

1. The wood nearer the heart of a stem or branch, different in color from the sapwood.

   Coordinate term: sapwood

   A popular myth is that heartwood is stronger than sapwood.

   • The staves are split from the heartwood. The heartwood is composed of dead cells; it supports the tree, but no longer has any physiological purpose. The staves must follow the grain of the wood to achieve a watertight cask, so they are split rather than sawn. — L'encyclopédie du Cognac: From log to stave
