Ponderosa Pine
Pinus ponderosa
A long-needled western pine with distinctive orange-brown plated bark that smells of vanilla or butterscotch in the sun. Deeply rooted and fire-adapted, it dominates dry interior forests. Drought stress predisposes it to mountain pine and western pine beetle attack.

Common questions
Why does my ponderosa bark smell sweet?
Mature ponderosa pine bark genuinely smells of vanilla or butterscotch, especially when warmed by sun. It is a normal and reliable ID trait for the species.
How do I protect a ponderosa from bark beetles?
Keep it vigorous with deep summer watering during drought, avoid wounding and fresh pruning in beetle flight season, and remove infested neighbors promptly to limit spread.
