Eastern Red Cedar
Juniperus virginiana • Softwood
Grain Pattern
Straight grain with a fine, even texture. This sample features a large, prominent tight knot with a 'teardrop' or 'plume' heartwood bleed, showing concentric growth rings and a slight radial crack (checking) within the knot itself. Flat-sawn orientation is visible.
Color Description
Heartwood is a distinct reddish to violet-brown, which contrasts sharply against the pale, creamy-white sapwood (seen in the majority of the board). The color tends to age to a silver-grey if left unfinished outdoors, or a more muted brown indoors over time.
Hardness Rating
900 lbf (Medium); though technically a softwood, it is harder than many other conifers and sits at the low end of the medium range.
Durability Rating
Very Durable; excellent resistance to rot and decay. The heartwood is highly resistant to termite attack and other insect damage due to its natural oils.
Common Uses
Fence posts, closet liners, chest linings, outdoor furniture, shingles, small novelty items, and essential oil production.
Geographic Origin
Eastern North America, ranging from southeastern Canada to the Gulf of Mexico.
Market Value & Sustainability
Estimated Market Value
$3.50 to $6.00 per board foot depending on grade and width.
Wood Age Estimate
The sample appears to be freshly milled or recently planed 'new stock,' likely harvested from a tree 30-50 years old based on the growth ring density in the knot area. Lack of significant UV greying suggests it is less than 2 years old post-milling.
Sustainability Status
Least Concern (IUCN); widely available and not considered threatened. Often considered an invasive species in some grassland regions of the US.
Workability
Generally easy to work with both hand and machine tools. It glues and finishes well. The large knots, as seen in this sample, can cause some tear-out or chipping if blades are not sharp.
Notable Features
Distinctive aromatic scent (classic cedar smell) that acts as a natural moth repellent. Highly stable with minimal warping. The sapwood/heartwood contrast is a primary aesthetic feature.
Finish Recommendations
Clear finishes like shellac or lacquer are recommended to preserve the color contrast. Often left unfinished in closets to maintain the aromatic scent. If used outdoors, a UV-inhibiting oil is necessary to prevent greying.
Identification Confidence
High; the vibrant reddish-purple heartwood knot surrounded by stark white sapwood, combined with the specific texture and ring structure, is characteristic of Juniperus virginiana.
