Rainbow Poplar
Liriodendron tulipifera • Hardwood
Grain Pattern
Straight, fine grain with a uniform texture. Features a rift-sawn appearance with vertical mineral staining streaks.
Color Description
Creamy white to yellowish-brown heartwood with dramatic mineral stains ranging from olive green to purple and black. Tends to darken and transition to brown with light exposure.
Hardness Rating
540 lbf (Soft)
Durability Rating
Non-durable; low resistance to rot or insect attack without chemical treatment.
Common Uses
Secondary wood for furniture frames, cabinetry, interior trim, picture frames, and small crafts where the mineral streaks are featured.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$3.50 - $6.50 per board foot depending on the intensity of the coloring.
Wood Age Estimate
Modern lumber, likely processed within the last 1-2 years based on lack of heavy oxidation and sharp, machine-cut edges.
Sustainability Status
Not listed on CITES or IUCN Red List; widely available and considered highly sustainable and fast-growing.
Workability
Excellent; one of the easiest hardwoods to machine, plane, and sand. Takes glue and nails well, though it can be fuzzy if tools are not sharp.
Notable Features
Often called 'Rainbow Poplar' due to mineral staining caused by mineral absorption from the soil. Faint scent when fresh; low toxicity.
Finish Recommendations
A clear UV-inhibiting topcoat or lacquer is recommended to preserve the purple and green hues, as they naturally fade to brown over time.
Identification Confidence
High; the distinct purple and green vertical mineral staining against a pale, fine-grained substrate is a classic diagnostic feature of Tulip Poplar.
