Diamond Willow
Salix spp. (typically Salix bebbiana or Salix rigida) • Hardwood
Grain Pattern
Irregular and contorted; dominated by deep diamond-shaped cankers (indentations) caused by the Valsa sordida fungus. Grain is typically fine-textured but twisted around the diamonds.
Color Description
Heartwood is a rich reddish-brown to dark brown; sapwood is a contrasting creamy white to tan. The high contrast between the recessed 'diamonds' and the sapwood create a striking visual pattern.
Hardness Rating
Approximately 400-600 lbf (Soft to Medium-Soft); Willow is generally soft but Diamond Willow varies due to dense cankers.
Durability Rating
Slightly Durable; the heartwood has modest rot resistance but the wood is primarily used indoors. It is susceptible to insect attack if not seasoned and finished.
Common Uses
Rustic furniture, walking sticks, canes, lamp bases, picture frames, and decorative folk art.
Geographic Origin
Northern North America, specifically Boreal regions of Canada and the Northern United States (Minnesota, Alaska, Montana).
Market Value & Sustainability
Estimated Market Value
$15.00 - $40.00 per individual stick or branch depending on the number and quality of diamonds.
Wood Age Estimate
Estimated 10-25 years old based on the diameter of the saplings and the depth of the fungal cankers, likely seasoned and used in furniture for 1-5 years.
Sustainability Status
Least Concern; not CITES listed. It is a common shrub/tree species and usually harvested from the wild in sustainably small quantities.
Workability
Challenging due to irregular shape; requires extensive hand-peeling of bark and careful sanding around diamonds. Glues and carves easily but lacks structural strength for heavy joinery.
Notable Features
Features unique diamond-shaped depressions caused by a fungal infection. It is prized for its aesthetic deformity rather than its structural properties. Lightweight with a faint, willow-like earthy scent.
Finish Recommendations
High-gloss polyurethane or lacquer is recommended to highlight the contrast between the dark diamonds and light sapwood. Teak oil or Danish oil also works well for a rustic look.
Identification Confidence
High; the distinctive diamond-shaped cankers and the contrast between the dark heartwood and creamy sapwood are unmistakable hallmarks of Diamond Willow.
