Rainbow Poplar
Liriodendron tulipifera • Hardwood
Grain Pattern
Straight, fine-textured grain with a flat-sawn cathedral appearance; features mineral stains and streaks caused by soil mineral absorption during growth.
Color Description
Creamy white to light yellow sapwood with distinct heartwood streaks of purple, green, black, and brown. Colors tend to darken and unify into a medium brown/olive with UV exposure.
Hardness Rating
540 lbf - Soft
Durability Rating
Non-durable; susceptible to decay and insect attack if left untreated or exposed to moisture.
Common Uses
Furniture, cabinetry, interior trim, picture frames, pallets, crates, and high-end veneer where color variation is desired.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$3.00 - $6.00 per board foot depending on the intensity of the mineral coloring.
Wood Age Estimate
Fresh-cut to early seasoned lumber; shows minimal oxidation or patina, suggesting it was processed recently (within 1-2 years).
Sustainability Status
Not listed by CITES or IUCN; considered highly sustainable and widely available.
Workability
Excellent workability with both hand and machine tools. It is easy to glue and finish, though its softness makes it prone to denting and fuzzy surfaces if using dull blades.
Notable Features
Often called 'Rainbow' Poplar due to heartwood mineral staining; it is lightweight, relatively odorless, and has very small pores that require little filling.
Finish Recommendations
Clear coat, polyurethane, or lacquer to preserve colors; however, UV-inhibiting finishes are highly recommended to slow the inevitable fading of the vibrant colors to brown.
Identification Confidence
High; the characteristic vertical mineral streaks of purple and green against the pale background are diagnostic for Liriodendron tulipifera heartwood.
