Poison Ivy (Woody Vine form)
Toxicodendron radicans • Hardwood (Dicotyledonous Vine)
Grain Pattern
Generally straight to irregular when in small stem form; however, the wood is extremely porous with prominent vessels (ring-porous).
Color Description
Heartwood is typically a pale yellow to light brown. Sapwood is creamy white. The wood lacks significant luster and may darken slightly to a dull tan with age.
Hardness Rating
Approximately 400-600 lbf (Very Soft to Soft). The wood is lightweight and lacks density, typical of fast-growing vines.
Durability Rating
Non-durable. The wood has very low resistance to decay and rot once dead, though the plant itself is highly resilient while living.
Common Uses
Almost never used for woodworking due to extreme toxicity; occasionally used in biological research or historical medicinal studies.
Geographic Origin
Native to Eastern North America, including parts of Canada, the United States, and Mexico.
Market Value & Sustainability
Estimated Market Value
No commercial value ($0.00). It is considered a hazardous pest and is not traded in the timber market.
Wood Age Estimate
The sample in the image appears to be from a young, first or second-year sapling or vine based on the stem diameter and leaf development.
Sustainability Status
Highly abundant and invasive in many regions; not listed by CITES or IUCN. No FSC certification exists for this species.
Workability
Extremely hazardous to work. Cutting or sanding releases urushiol-laden dust which causes severe allergic reactions (dermatitis) and can lead to internal respiratory distress if inhaled.
Notable Features
Contains Urushiol, a potent skin irritant. Burning the wood is extremely dangerous as the toxins become airborne in smoke.
Finish Recommendations
Not applicable. Finishing is not recommended due to the health risks involved in handling any part of the plant structure.
Identification Confidence
High. The identification is based on the 'leaves of three' trifoliate arrangement, the distinctively lobed/notched margins, and the presence of aerial rootlets on the woody stem.
