Soft, fine-grained wood of the species Liriodendron tulipifera of North America. The sapwood is usually a creamy off-white color; heartwood is pale green, often with streaks of red, purple, or black. It is cheap, easy-to-work, can take a sharp edge, and is stable, used to seal pipes and valves in organs, for siding clapboards, coffin boxes, pattern timber, and wooden ware.
