The Story
Plant Bio
Pinus ponderosa is a large, long-lived coniferous evergreen tree, iconic in the American West. It is distinguished by its long needles in bundles of three and mature bark that is orange-brown and plated, smelling of vanilla or butterscotch when warmed by the sun. As a keystone species, its primary distinction is its ecological role and majestic stature. Its thick, fire-resistant bark allows it to survive low-intensity ground fires, shaping the forest ecosystems where it dominates.

Planting
How to Grow
- Select a site in full sun with deep, well-drained soil.
- Dig a hole two to three times the width of the root ball.
- Place the tree in the hole, ensuring the root flare is at or slightly above soil level.
- Backfill with the native soil, breaking up any large clumps.
- Water deeply after planting to settle the soil.
- Provide supplemental water for the first 1-2 years until established.
Pro Tip
Give it ample space to grow to its mature size; this is not a tree for a small residential lot. It thrives on neglect once established.
Keep It Thriving
Care Guide
Do
- Allow the soil to dry out between waterings once established.
- Provide plenty of room for both vertical and horizontal growth.
- Allow lower branches to remain on young trees to help trunk development.
- Appreciate its natural, open form; it does not require shearing.
Don't
- Do not plant in shady or poorly drained locations.
- Avoid planting in small, confined spaces or under power lines.
- Do not overwater; this tree is extremely drought tolerant.
- Avoid fertilizing; it is adapted to lean soils.
